Power Query Advanced Reshaping: Merge, Unpivot & M Code 2026

Why Advanced Data Reshaping Matters for Analysts

Are you spending countless hours manually combining data from disparate sources or wrestling with reports structured poorly for analysis? You are not alone. For analysts and finance professionals, transforming raw, messy data into reporting-ready tables is a constant challenge. Mastering advanced Power Query techniques is not just about efficiency; it's about accuracy, repeatability, and gaining deeper insights faster.

Modern data demands more than basic cleaning. You need to confidently merge multiple data sources, restructure 'wide' data into 'tall' formats, and even customize transformations with code. This guide will walk you through essential advanced Power Query strategies, ensuring your data pipelines are robust and your reports are insightful by 2026 and beyond.

Mastering Table Merges: Your Power Query Merge Tables Tutorial

Combining data from different tables is a cornerstone of data analysis. Whether you're integrating sales data with customer demographics or blending financial actuals with budget figures, Power Query's merge capabilities are indispensable. This power query merge tables tutorial will show you how to do it efficiently.

The 'Merge Queries' feature in Power Query's Query Editor allows you to combine two tables based on matching values in one or more columns. It's similar to a VLOOKUP or JOIN operation in SQL, but far more powerful and dynamic.

Step-by-Step: Merging Sales and Customer Data

Imagine you have two data sources: one with sales transactions (SalesData) and another with customer details (CustomerDetails). Both share a 'CustomerID' column.

Load Data: First, ensure both SalesData and CustomerDetails are loaded into the Power Query Editor from their respective data source locations.

Select Primary Table: In the Query Editor, select the SalesData query.

Initiate Merge: Go to the 'Home' tab and click 'Merge Queries' (or 'Merge Queries as New' if you want to preserve the original tables).

Choose Second Table: In the 'Merge' dialog box, select CustomerDetails from the dropdown as the second table.

Select Matching Columns: Click on the 'CustomerID' column in both tables to indicate the matching key. If you have multiple matching columns, hold 'Ctrl' and select them in the same order for both tables.

Choose Join Kind: Select the 'Join Kind'. For instance, 'Left Outer (all from first, matching from second)' is common, bringing all sales data and only matching customer details.

Expand Columns: After the merge, you'll see a new column in SalesData named 'CustomerDetails' containing Table objects. Click the expand icon (▶ ▼) in its header. Uncheck 'Use original column name as prefix' and select the customer fields you need (e.g., 'CustomerName', 'Region').

Review and Refine: Examine the results. The new columns from CustomerDetails are now integrated into SalesData. Adjust data types if necessary.

Each of these operations becomes an applied step in the Query Editor, making your merge repeatable with a single refresh.

Efficiently Reshaping Data with Power Query Unpivot Columns Example

Often, data arrives in a 'wide' format where attributes are spread across columns rather than stacked vertically. For example, monthly sales figures might be in separate columns like 'Jan Sales', 'Feb Sales', 'Mar Sales'. This structure is problematic for reporting tools and many analyses. The 'Unpivot Columns' transformation is a powerful feature of Excel Power Query that solves this.

Unpivoting transforms selected columns into attribute-value pairs, creating a 'tall' dataset that is much easier to analyze, filter, and summarize.

Practical Power Query Unpivot Columns Example: Monthly Sales

Consider a dataset with sales figures for different products across several months:

ProductJanuaryFebruaryMarchAprilWidget A120135140155Gadget B8095100110Tool C200210225230

To unpivot this data into a more usable format:

Load Data: Get this table into the Power Query Editor.

Select Identifier Columns: Identify columns that should remain as identifiers. In this case, 'Product'.

Select Columns to Unpivot: Select the columns you want to unpivot ('January', 'February', 'March', 'April'). You can do this by clicking the first column, then holding 'Shift' and clicking the last, or holding 'Ctrl' to select individual columns.

Apply Unpivot: Go to the 'Transform' tab. Click 'Unpivot Columns'. You have three options:

Unpivot Columns: Unpivots only the selected columns.

Unpivot Other Columns: Unpivots all columns *except* the selected ones (useful if you have many columns to unpivot and few identifiers).

Unpivot Only Selected Columns: Behaves like 'Unpivot Columns'.

In our example, choose 'Unpivot Columns'.

Rename Columns: Power Query will create two new columns, typically named 'Attribute' (for the month names) and 'Value' (for the sales figures). Rename 'Attribute' to 'Month' and 'Value' to 'Sales Amount'.

Adjust Data Types: Ensure the 'Sales Amount' column is set to a numeric data type (e.g., Decimal Number) and 'Month' is Text.

The resulting table will look like this, which is ideal for calculating total sales by month or product:

ProductMonthSales AmountWidget AJanuary120Widget AFebruary135Widget AMarch140Widget AApril155Gadget BJanuary80Gadget BFebruary95Gadget BMarch100Gadget BApril110Tool CJanuary200Tool CFebruary210Tool CMarch225Tool CApril230

This transformation is a game-changer for anyone dealing with cross-tabulated data, simplifying complex analyses and enabling robust reporting.

Diving Deeper with Power Query M Code Examples

While the Query Editor's graphical interface handles most tasks, understanding the underlying M language unlocks Power Query's full potential. M code allows for custom, highly specific transformations that might be difficult or impossible with the point-and-click interface. You can view or edit M code for any applied step by selecting the step and looking at the formula bar, or by clicking 'Advanced Editor' on the 'Home' tab.

Custom Column Creation with M

Creating a custom column is one of the most common applications of M code. Suppose you need to calculate 'Profit Margin' from 'Revenue' and 'Cost' columns.

= Table.AddColumn(#"Renamed Columns", "Profit Margin", each ([Revenue] - [Cost]) / [Revenue], type number)

This M code snippet adds a new column named "Profit Margin" to the previous step (referenced by #"Renamed Columns"), calculating it for each row and explicitly setting its data type as 'number'.

Conditional Logic for Enhanced Data Categorization

You can use M to create powerful conditional logic, similar to Excel's IF statements, but within your data transformation pipeline.

= Table.AddColumn(#"Changed Type", "Sales Tier", each if [Sales Amount] >= 500 then "High Value" else if [Sales Amount] >= 200 then "Medium Value" else "Low Value", type text)

This example categorizes sales into "High Value," "Medium Value," or "Low Value" based on their 'Sales Amount'. This is a practical example of how to use power query m code examples for analytical purposes.

Dynamic Filtering with Parameters

For more advanced scenarios, parameters enable dynamic filtering or data source selection without modifying the query itself. You can define a parameter (e.g., 'Target_Region') and then incorporate it into your M code for filtering:

= Table.SelectRows(#"Changed Type", each [Region] = Target_Region)

This allows you to change the `Target_Region` parameter and instantly refresh your query to show data for a different region, providing incredible flexibility for reporting dashboards.

Beyond the Basics: Power Query Tips and Tricks 2026

To truly optimize your data transformation workflow, consider these advanced tips and tricks:

Leverage 'Group By': The 'Group By' feature (under 'Transform' tab) is incredibly powerful for summarization. You can group by one or more columns and then perform aggregate functions like Sum, Average, Min, Max, Count, etc. This is perfect for generating summary tables from detailed transaction data.

Understanding the 'Applied Steps' Pane: Every transformation you make is recorded here. You can reorder, edit, or delete steps. This is crucial for debugging and optimizing your queries. Renaming steps descriptively will significantly improve readability for future maintenance.

Utilize 'Reference' vs. 'Duplicate': When creating new queries based on existing ones, 'Reference' creates a link, meaning changes to the original query affect the referenced one. 'Duplicate' creates an independent copy. Choose wisely based on whether you need dependencies.

Error Handling: Power Query handles errors gracefully. You can 'Remove Errors' from columns or 'Replace Errors' with specific values. For more control, use `try ... otherwise ...` statements in M code for robust error management in column operations.

Custom Functions: For repetitive tasks, encapsulate common M code patterns into reusable custom functions. This promotes modularity and reduces redundancy, making your power query solutions highly scalable.

By incorporating these power query tips and tricks 2026, you'll build more efficient, resilient, and insightful data models.

Common Pitfalls and How to Avoid Them

Even with advanced knowledge, certain traps can derail your Power Query efforts:

Ignoring Data Types: Always set correct data types early in your query. Incorrect data types can lead to errors, slow performance, and incorrect calculations, especially when performing merges or aggregations.

Over-expanding Merged Columns: When merging tables, only expand the columns you actually need. Expanding all columns can clutter your query, degrade performance, and make it harder to manage.

Hardcoding Values: Avoid embedding static values (like file paths or filter criteria) directly into your M code. Use parameters for dynamic inputs, making your queries more flexible and easier to update.

Complex Steps without Explanations: The 'Applied Steps' pane can become a long list of obscure operations. Rename steps clearly and add comments in the Advanced Editor if you're using complex M code.

Not Saving Your Work: While Power Query automatically saves steps in Excel workbooks, if you're working with standalone Power Query files (PQX), remember to save regularly.

By being mindful of these common issues, you can build more robust and maintainable Power Query solutions for any data transformation challenge.

The Quiet Rise of Companions Who Have a History

Spend an afternoon watching people set up an AI girlfriend on sweetdream.ai and you notice something unexpected. They linger. Before they ever start a conversation, they are deciding whether she grew up by the sea or in some loud city, whether she is the type to text first or wait. The character builder on SweetDream invites that kind of patience, letting users shape looks, voice, temperament and an actual backstory rather than picking from a thin menu of presets.

What stands out, observationally, is how much the backstory changes the chat itself. Because SweetDream's conversations are emotionally intelligent and remember context, a companion with a defined past starts referencing it on her own, the way a real person carries their history into a relationship. The effect is subtle the first day and striking by the second week.

Plenty of platforms promise an AI companion. Tools like candy.ai and ourdream.ai have their followers. But the people I watched kept returning to SweetDream specifically because the personality felt authored, not assembled, and because everything they built stayed entirely private.

Imagine your goal is to understand sales performance across different product categories and regions, including year-over-year comparisons.

Phase 1: Data Preparation & Cleaning with AI

Data rarely arrives perfectly clean. Manual data cleaning is often the most time-consuming part of any analysis. Copilot can dramatically reduce this burden.

Your Action: Load your raw sales data into Excel. It might have missing values, inconsistent formatting, or duplicate entries.

Copilot Prompt: "Analyze this sales data. Identify and flag any incomplete rows in column B and suggest how to handle them. Also, check for and remove any duplicate entries based on the 'Transaction ID' column."

Copilot's Response: Copilot will scan your data, highlight rows with missing information using conditional formatting, and provide options to delete duplicates or fill gaps. It might suggest a specific formula for imputation or simply ask for your preference. This immediate visual feedback and actionable suggestions save hours.

Phase 2: Formula Generation & Complex Calculations

Once your data is cleaner, you need to derive meaningful metrics. This often involves complex formulas that can be daunting to construct manually.

Your Action: You need to calculate the total sales for each product category and then determine the percentage contribution of each category to overall sales. Additionally, you want to see the year-over-year sales growth.

Copilot Prompt: "For the 'Sales Amount' column, create a new column named 'Category Total Sales' that sums sales for each unique 'Product Category'. Then, add another column 'Sales Contribution %' that calculates each category's percentage of overall sales. Finally, generate a formula using dynamic arrays to show the year-over-year growth for total sales, assuming sales data for the prior year is in columns A:C of 'Sheet2'."

Copilot's Response: Copilot will generate the necessary formulas, potentially using SUMIFS for category totals, basic division for percentages, and advanced XLOOKUP or FILTER functions combined with dynamic arrays for the year-over-year calculation. It will display these formulas directly in the formula bar and apply them to your data, explaining its logic. This is an excellent excel ai formula generator tutorial in action.

Phase 3: Dynamic Reporting & Insights

The final step is to synthesize your findings into an easily digestible report, often using PivotTables and charts.

Your Action: You want a summary table of sales performance and a visual representation of the trends.

Copilot Prompt: "Create a PivotTable summarizing total sales by 'Region' and 'Product Category' for the current quarter. Include 'Average Discount' as a value field. Then, suggest a suitable chart to visualize the regional sales performance. Finally, summarize the top 3 performing product categories and regions in natural language."

Copilot's Response: Copilot will instantly create a comprehensive PivotTable, pre-configured with the specified fields and aggregations. It will then suggest a bar chart or column chart to visualize regional sales and, importantly, provide a concise text summary of your top performers directly in the chat pane, saving you the effort of manually extracting insights.

These advanced features cement Copilot's role as a powerful AI assistant, transforming how you approach spreadsheet automation and complex data analysis within your workbook.

Crafting Effective Prompts: Best Practices for Excel Copilot

The effectiveness of Copilot largely depends on the clarity and specificity of your prompts. To get the best results from your excel copilot, consider these best practices:

Be Specific: Instead of "Analyze sales," try "Show me the total sales for each product category in Q2 2026."

Provide Context: Refer to specific sheet names, column headers, or ranges (e.g., "Using the 'Sales Data' sheet, filter column C for 'Region North'").

Break Down Complex Tasks: For very involved analyses, break your request into smaller, manageable steps.

Iterate and Refine: If the initial output isn't perfect, don't hesitate to provide follow-up instructions (e.g., "Now, sort that PivotTable by total sales in descending order").

Ask for Explanations: If you don't understand Copilot's output, ask it to explain the formula or the logic it used.

Mastering prompt engineering for Microsoft Copilot Excel is key to unlocking its full potential and truly speeding up your data work.

Step 2: Make Your First API Call

n

Create a new Jupyter Notebook cell and try a simple completion request:

n

from openai import OpenAInnclient = OpenAI()nndef get_completion(prompt, model='gpt-3.5-turbo'):n messages = [{"role": "user", "content": prompt}]n response = client.chat.completions.create(n model=model,n messages=messages,n temperature=0.7 # Controls randomness, lower is more focusedn )n return response.choices[0].message.contentnnprint(get_completion("What is the capital of France?"))n

n

You should see a response like "The capital of France is Paris." This confirms your API connection is working.

nn

Step 3: Build an Interactive Chat Loop

n

To create a chatbot, you need a loop that continuously takes user input and sends it to the model. We'll also maintain a simple history of the conversation to provide context.

n

def chat_bot():n print("Hello! I'm your AI assistant. Type 'quit' to exit.")n messages = [] # Stores conversation historynn while True:n user_input = input("You: ")n if user_input.lower() == 'quit':n breakn n messages.append({"role": "user", "content": user_input})n n # Get AI's responsen response = client.chat.completions.create(n model='gpt-3.5-turbo',n messages=messages,n temperature=0.7n )n n ai_response = response.choices[0].message.contentn print(f"AI: {ai_response}")n messages.append({"role": "assistant", "content": ai_response})nnchat_bot()n

n

This basic python openai api tutorial step by step creates a functional chatbot. Each user input and AI response is added to the messages list, providing the model with conversational context. This simple memory allows for more coherent interactions.

nn

Enhancing Your Chatbot with Python LangChain Tutorial for Beginners

n

While the basic chatbot works, it can quickly become unwieldy for more complex tasks or persistent memory. This is where langchain shines. LangChain provides abstractions that make it easier to build sophisticated applications with LLMs, including managing conversation history and connecting to external tools.

nn

Using LangChain for a Smarter Chatbot

n

Let's refactor our chatbot using LangChain's components. This will introduce concepts like LLM chains and memory.

n

n

Import LangChain Components: Start by importing the necessary classes from langchain and langchain_openai.

n

from langchain_openai import ChatOpenAInfrom langchain.chains import ConversationChainnfrom langchain.memory import ConversationBufferMemoryn

n

n

n

Initialize the LLM and Memory: LangChain allows you to easily plug in different LLMs. We'll use ChatOpenAI. For memory, ConversationBufferMemory stores the full conversation history.

n

llm = ChatOpenAI(temperature=0.7, model_name="gpt-3.5-turbo")nmemory = ConversationBufferMemory()n

n

n

n

Create a Conversation Chain: The ConversationChain links the LLM with memory, handling the input/output formatting automatically.

n

conversation = ConversationChain(n llm=llm,n memory=memory,n verbose=False # Set to True to see LangChain's internal thought processn)n

n

n

n

Run the Chatbot Loop with LangChain: Now, your interaction loop becomes much simpler, as LangChain manages the context.

n

print("LangChain Chatbot: Hello! I'm your advanced AI assistant. Type 'quit' to exit.")nwhile True:n user_input = input("You: ")n if user_input.lower() == 'quit':n breakn n response = conversation.predict(input=user_input)n print(f"LangChain Chatbot: {response}")n

n

n

n

With LangChain, your code is cleaner, and you gain powerful features like different memory types (e.g., summarization memory for longer conversations) or tool integration without rewriting core logic. This python langchain tutorial for beginners demonstrates how to build a robust, conversational AI with minimal effort.

Elevating Dashboard Design with Power BI Copilot Features Tutorial

Power BI Copilot is arguably one of the most transformative AI features for business analysts and BI developers. It acts as an intelligent assistant, streamlining everything from report creation to the generation of dynamic narratives. This comprehensive power bi copilot features tutorial explores how you can leverage its power.

Generating Reports and Summaries

Copilot can generate entire report pages or summaries based on your data and natural language prompts. Imagine simply telling Power BI what you want to see, and it begins to lay out the visuals and key metrics for you. This dramatically accelerates the initial dashboard design phase, allowing you to focus on refinement rather than construction from scratch.

For example, you could ask Copilot:

'Create a report showing sales performance by region and product category, including a KPI for profit margin.' or 'Summarize the key drivers of customer churn from my customer data model.'

Copilot will then analyze your data modeling and suggest appropriate visualizations, creating a foundation that you can further customize.

Crafting Engaging Narratives with Smart Narratives

Beyond visuals, AI helps you tell the story behind your data. Smart Narratives, enhanced by Copilot, automatically generate textual summaries of your reports and dashboards. These narratives update dynamically with your data, explaining key findings, trends, and outliers in plain language.

It shows you the most significant contributors to a selected metric, offering actionable insights for improving KPIs.

Anomaly Detection: Automatically identifies unusual data points in your time-series data. This can be crucial for spotting sudden dips in sales, unexpected spikes in website traffic, or unusual equipment failures, allowing for proactive intervention.

These features enable a deeper drillthrough into causality, providing explanations for 'why' certain things are happening, not just 'what' is happening.

Automating Insights and Refresh Schedules

Maintaining up-to-date and insightful reports can be time-consuming. Power BI AI helps automate various aspects, ensuring your dashboards always reflect the latest data and provide fresh insights with minimal manual intervention.

Streamlining Data Refresh with AI

While not a direct AI feature, intelligent refresh schedules can be optimized by understanding data usage patterns. Power BI service monitors how and when your reports are accessed, and while you set the refresh schedule, AI-driven monitoring can highlight inefficiencies or suggest optimal times, ensuring your data is always current when your audience needs it most.

Leveraging AI for Proactive KPI Monitoring

You can configure Power BI to use AI-driven alerts for your KPIs. For instance, if a sales target is projected to be missed based on current trends, or if a critical operational metric deviates significantly from its baseline, Power BI can send automated notifications. This proactive monitoring ensures that managers and business analysts are immediately aware of critical developments, enabling timely decision-making.

Real-World Impact: A Mini Case Study

Consider a retail manager struggling to understand regional sales performance and inventory levels across hundreds of stores. Manually creating reports for each region and product line was a monumental task, often leading to outdated information by the time it reached decision-makers.

The Power BI AI Workflow:

Data Ingestion & Cleaning: Sales and inventory data from various POS systems were fed into Power BI. Power Query's AI capabilities helped standardize product names and merge disparate store IDs.

Copilot Report Generation: The manager used Power BI Copilot to generate an initial dashboard layout showing regional sales, top-selling products, and current inventory. Prompts like 'Show me regional sales variance from last quarter and inventory levels for categories with low stock' quickly formed the basis of the report.

AI Visuals for Insights: Key Influencers were applied to sales data to identify factors driving high or low performance in specific regions (e.g., promotional campaigns, local events). Anomaly Detection highlighted unusual stock fluctuations, preventing potential overstocking or stockouts.

Natural Language Interaction: Store managers could then use the Q&A feature to ask specific questions like 'What was the sales trend for product X in the East region last month?' without needing a pre-built report for every query.

Automated Alerts: Alerts were set up to notify the retail manager if a specific product's inventory dropped below a critical threshold in any region, or if daily sales targets were significantly off track.

Result: The retail manager transformed from reactive problem-solving to proactive strategic planning. They could pinpoint issues faster, understand underlying causes, and make data-driven decisions on promotions and inventory allocation, ultimately boosting profitability and customer satisfaction. This comprehensive use of power bi ai made the difference.

Mastering Excel Power Query: Merge vs Append Tables 2026

Are You Drowning in Disparate Data? Master Power Query's Merge & Append!

As a data analyst or reporting professional, you regularly face the challenge of combining data scattered across multiple spreadsheets, databases, or online sources. Inconsistent formats, missing values, and the sheer volume of information can make meaningful analysis feel impossible. Fortunately, excel power query offers powerful tools to tackle these issues, specifically its Merge and Append functions.

This guide will demystify the core differences between these two vital operations, showing you precisely when and how to use them to streamline your data consolidation. We'll also explore how Microsoft Copilot can accelerate your excel etl with power query and copilot workflows, transforming you into a data consolidation master by July 2026.

Understanding Data Consolidation in Excel ETL

Effective data consolidation is the backbone of reliable reporting and insightful analytics. Without a unified, clean dataset, your conclusions can be flawed, and your reports inconsistent. This is where the ETL (Extract, Transform, Load) process becomes critical, and Power Query excels at the 'Transform' stage.

The ETL Process with Power Query

Power Query provides a robust, user-friendly interface for performing complex data transformation tasks. It allows you to connect to various data source types, clean the data, reshape it, and then load it into Excel or the Data Model. This non-destructive approach means your original data remains untouched, providing a safe sandbox for experimentation.

Why Merge and Append are Crucial for Data Analysts

Most real-world scenarios involve data residing in multiple tables or files. Imagine customer information in one table, their purchase history in another, and sales figures broken down by month across several different files. To gain a holistic view, you need to combine these pieces effectively. Merge and Append are Power Query's primary mechanisms for achieving this, allowing you to build comprehensive datasets for analysis.

Power Query Merge vs Append Tables: The Fundamental Difference

While both Merge and Append consolidate data, they do so in fundamentally different ways, addressing distinct analytical needs. Understanding this distinction is key to mastering excel power query for complex data scenarios.

What is 'Merge Queries'? (Joins)

Think of Merge as combining tables horizontally, adding columns from one table to another. You use Merge when you have two or more tables with related information that share a common key or identifier. For example, you might have a 'Sales Orders' table and a 'Customers' table, both containing a 'CustomerID'. Merging these tables allows you to bring customer details (like name, address) into your sales data.

Power Query offers several types of joins, mirroring SQL join functionality:

Left Outer: All rows from the first table, and matching rows from the second.

Right Outer: All rows from the second table, and matching rows from the first.

Full Outer: All rows from both tables, matching where possible.

Inner: Only rows where there's a match in both tables.

Left Anti: Rows in the first table that have no matching rows in the second.

Right Anti: Rows in the second table that have no matching rows in the first.

What is 'Append Queries'? (Unions)

Append combines tables vertically, stacking rows from one table beneath another. You use Append when you have multiple tables with the same structure (i.e., identical column headers and data types) but containing different sets of records. A classic example is monthly sales reports, each in a separate file, which you want to combine into a single, annual sales record.

Feature Merge Queries Append Queries Purpose Combine columns from related tables Combine rows from similarly structured tables Direction Horizontal expansion Vertical stacking Key Requirement Common column(s) for matching Identical column headers & data types Analogy SQL JOIN SQL UNION ALL

When to Use Merge: Combining Related Data from Multiple Sources

You'll predominantly use Merge operations when your data is normalized across multiple tables, and you need to bring related attributes together. This is a core part of many data transformation scenarios.

Common Merge Scenarios

Linking sales transactions to customer demographics.

Attaching product details to inventory records.

Combining employee information with their departmental assignments.

Worked Example: Merging Sales with Product Information

Imagine you have two tables loaded into your Power Query editor:

Sales Data: Contains 'OrderID', 'ProductID', 'Quantity', 'Date'.

Product Catalog: Contains 'ProductID', 'ProductName', 'Category', 'UnitPrice'.

You want to add 'ProductName' and 'UnitPrice' to your Sales Data.

Select your 'Sales Data' query in the query editor.

Go to the 'Home' tab, then click 'Merge Queries' (or 'Merge Queries as New' if you want to preserve the original).

In the Merge dialog, select 'Product Catalog' as the second table.

Click the 'ProductID' column in both preview tables to establish the matching key.

Choose 'Left Outer' join kind (to keep all sales records and bring in matching product info).

Click 'OK'. A new column will appear in your 'Sales Data' query, containing nested tables from the 'Product Catalog'.

Click the expand icon in the new column's header, uncheck 'Use original column name as prefix', and select 'ProductName' and 'UnitPrice'.

Click 'OK' to see your merged data, now enriched with product details.

When to Use Append: Stacking Similar Data from Disparate Files

Append operations are your go-to when you have consistent data structures spread across various files, sheets, or even database tables, and you need to consolidate them into one master list.

Typical Append Scenarios

Consolidating monthly sales reports into an annual report.

Combining lead generation data from different marketing campaigns.

Aggregating sensor readings from multiple devices, each recording similar metrics.

Worked Example: Appending Quarterly Sales Data

Suppose you have three Excel files: 'Q1_Sales.xlsx', 'Q2_Sales.xlsx', and 'Q3_Sales.xlsx'. Each file has sheets named 'Sales Data' with identical columns: 'Date', 'Region', 'Product', 'Revenue'.

Load each 'Sales Data' sheet from the three files as separate queries in Power Query.

Select your 'Q1_Sales' query.

Go to the 'Home' tab, then click 'Append Queries' (or 'Append Queries as New').

If appending two tables, select 'Two tables' and choose 'Q2_Sales'. If more, select 'Three or more tables' and add 'Q2_Sales' and 'Q3_Sales' to the 'Tables to append' list.

Click 'OK'. The rows from Q2 and Q3 will be stacked beneath Q1's data.

Ensure your data types are consistent across all columns post-append to avoid errors.

Supercharging Your ETL with Microsoft Copilot and Power Query M

Modern data analysts don't just work with tools; they collaborate with AI. Microsoft Copilot can significantly enhance your excel etl with power query and copilot experience, especially when dealing with complex Merge and Append scenarios.

Leveraging Copilot for Merge/Append Efficiency

Copilot, integrated directly into Excel, can act as your intelligent assistant. If you're unsure about the right join type for a merge, or need to quickly consolidate data from several sources, you can ask Copilot. It can suggest the appropriate Power Query steps, generate M code for specific transformations, or even help identify potential schema mismatches before you append tables. This accelerates your learning and execution, allowing you to focus on analysis rather than syntax.

Advanced Transformations with Power Query M Language Examples

While the Query Editor's UI is powerful, the underlying Power Query M language offers unparalleled flexibility. For highly customized merges, conditional appends, or dynamic parameters, M code is your friend. Copilot can even help you generate or refine M code snippets.

For instance, to dynamically merge based on a parameter or perform a fuzzy merge, you might dive into M. Here's a simple M function example that could be used in a custom column or advanced editor:

(SourceTable as table, LookupTable as table, KeyColumn as text) as table => Table.Join(SourceTable, KeyColumn, LookupTable, KeyColumn)

This illustrates how functions in M can generalize common operations, making your queries more robust and reusable. You can also use M for complex conditional logic before merging or appending, or to implement advanced error handling.

Best Practices for Robust Data Consolidation

To ensure your merged and appended data is accurate and reliable, follow these best practices:

Pre-clean Your Data: Before attempting any merge or append, ensure your source tables are clean. Use Power Query to remove duplicates, handle nulls, and rectify inconsistent spellings. This addresses the challenge of how to clean messy data in excel power query proactively, preventing issues downstream.

Standardize Column Names and Data Types: Especially for append operations, identical column headers and consistent data types are non-negotiable. For merges, ensure your key columns are of the same data type.

Validate Your Joins/Unions: Always check the results of your merge or append. Do you have the expected number of rows? Are the new columns populating correctly? Use Power Query's profiling tools to quickly assess data quality after a transformation.

Consider Performance: For very large datasets, be mindful of the order of operations. Pushing down transformations to the source database where possible can significantly improve performance. Be aware of transformations like pivot unpivot, which can drastically reshape your data and impact subsequent consolidations.

Use Query Parameters: For dynamic data sources or recurring reports, define parameters for file paths or table names. This makes your ETL workflows more flexible and easier to update.

Many professionals struggle with inefficient data preparation, but there's a powerful solution built right into Excel that can transform your workflow: Power Query.

This comprehensive guide offers a step-by-step power query tutorial for beginners step by step, showing you exactly how to use Power Query in Excel to automate your data transformation process. We'll demystify the core functionalities, walk through practical examples, and equip you with the foundational skills to become a data transformation wizard. By the end of this tutorial, you'll be well on your way to mastering the essential techniques for clean, reporting-ready data, every time.

Getting Started: Accessing the Power Query Editor in Excel

Before you can unleash the full potential of data transformation, you need to know where to find Power Query. Fortunately, it's integrated seamlessly into modern versions of Excel (Excel 2016 and later, including Excel 2026). You don't need to install any separate add-ins.

Locating the 'Get & Transform Data' Group

The entry point for Power Query is usually located on the 'Data' tab of the Excel ribbon. Look for the 'Get & Transform Data' group. This is your gateway to connecting with various `data source` types and launching the `query editor`.

Open your Excel workbook.

Navigate to the 'Data' tab on the ribbon.

In the 'Get & Transform Data' group, click 'Get Data' to start a new query, or 'Launch Power Query Editor' if you've already created queries in the workbook.

Once you select a data source and begin importing, the Power Query Editor window will open. This dedicated environment is where all your data transformation magic happens.

Connecting Your Data: The First Step in Power Query

The first crucial step in any data transformation journey is connecting to your raw data. Power Query boasts an impressive array of connectors, allowing you to pull data from almost anywhere.

Common Data Sources for Analysts

From File: Excel Workbooks, CSVs, Text files, XML, JSON, Folders (combining multiple files).

From Database: SQL Server, Access, Oracle, IBM Db2, MySQL, PostgreSQL, etc.

From Azure: Azure SQL Database, Azure Synapse Analytics, etc.

From Online Services: SharePoint Online List, Microsoft Exchange Online, Dynamics 365, Salesforce objects, Google Analytics, Facebook, OData Feed, etc.

From Other Sources: Web (importing data from a webpage), OLE DB, ODBC, Blank Query.

For most finance professionals and analysts, starting with data 'From File' (especially Excel workbooks or CSVs) is the most common scenario. Let's assume you have an Excel file named 'RawSalesData.xlsx' with sales figures that need cleaning.

Step-by-Step: Connecting to an Excel Workbook

From the 'Data' tab, click 'Get Data' > 'From File' > 'From Excel Workbook'.

Browse to your 'RawSalesData.xlsx' file and click 'Import'.

The Navigator pane will appear, showing you the sheets or tables within your workbook. Select the specific sheet or table you want to import.

Click 'Transform Data'. This will open the Power Query Editor, bringing your selected data in for manipulation.

Essential Data Transformations for Analysts

Once your data is loaded into the Power Query Editor, you'll see your data preview. On the right-hand side, you'll notice the 'Applied Steps' pane. This is a critical feature, recording every transformation you make. You can review, reorder, or delete `applied steps` at any time, making your process transparent and editable.

Standardizing Data Types and Column Operations

One of the most frequent tasks is ensuring your `data types` are correct. Incorrect data types can lead to errors in calculations or filtering. Power Query often attempts to detect data types automatically, but it's essential to verify.

Here are some fundamental `column operations` you'll perform regularly:

Changing Data Types: Click the icon in the column header (e.g., '123' for number, 'ABC' for text) and select the correct type (e.g., Whole Number, Decimal Number, Date, Text).

Removing Columns: Select the column(s) and press 'Delete' or right-click > 'Remove Columns'.

Renaming Columns: Double-click the column header and type a new name.

Splitting Columns: Useful for separating combined data (e.g., 'First Name Last Name' into two columns). Right-click > 'Split Column' by Delimiter, Number of Characters, etc.

Filling Down/Up: Essential for cleaning hierarchical data where values are only present in the first row of a group. Right-click > 'Fill' > 'Down' or 'Up'.

Removing Duplicates: Select the column(s) that define uniqueness, right-click > 'Remove Duplicates'.

Filtering Rows: Use the filter icon in the column header, just like in Excel, to keep or remove specific rows.

Grouping Data: The `group by` feature allows you to aggregate data based on one or more columns (e.g., sum sales by region).

Worked Example: Cleaning and Standardizing Sales Data

Imagine your 'RawSalesData' has a 'Product_ID' column that's currently text, a 'Sales_Amount' that's sometimes text with currency symbols, and a 'Region' column with some blank cells you need to fill down.

Load Data: Connect to 'RawSalesData.xlsx' as described above.

Rename Columns: Double-click on 'Prod ID' and rename it to 'Product ID'.

Change Data Type (Sales_Amount): Select the 'Sales_Amount' column. Click the 'ABC 123' icon in its header, then choose 'Decimal Number'. If there are errors (e.g., currency symbols), Power Query will prompt you to replace values or remove errors. Often, 'Replace Values' (e.g., replace '$' with nothing) is the first step before changing the type.

Fill Down (Region): Select the 'Region' column. Right-click on the column header, go to 'Fill' > 'Down'. This will fill nulls with the value from the previous non-null cell.

Remove Duplicates: Select both 'Product ID' and 'Sales_Date' columns (assuming their combination defines a unique transaction). Right-click > 'Remove Duplicates'.

With just a few clicks, your data is significantly cleaner and ready for more complex analysis. Each action is recorded in the 'Applied Steps' pane, creating a repeatable process.

Powerful Shaping: Unpivoting and Merging Tables

Beyond basic cleaning, Power Query excels at reshaping data for analytical purposes. Two powerful transformations are unpivoting and merging.

Understanding Unpivot: The `Power Query Unpivot Columns Example`

Unpivoting is a game-changer for converting cross-tabulated data (where categories are spread across columns) into a tall, tabular format suitable for analysis in PivotTables or other reporting tools. This is a common `pivot unpivot` scenario.

Consider sales data where months (Jan, Feb, Mar) are separate columns, and you want them as a single 'Month' column with corresponding 'Sales' values:

Product | Jan | Feb | Mar --------|-----|-----|----- A | 100 | 120 | 110 B | 150 | 130 | 160

Here's how to perform a `power query unpivot columns example`:

Select the 'Product' column (the identifier column you want to keep).

Go to the 'Transform' tab in the Power Query Editor.

Click 'Unpivot Columns' dropdown, then choose 'Unpivot Other Columns' (this means unpivot all *other* columns besides the selected 'Product' column).

Your data will transform into:

Product | Attribute | Value --------|-----------|------ A | Jan | 100 A | Feb | 120 A | Mar | 110 B | Jan | 150 B | Feb | 130 B | Mar | 160

You can then easily rename 'Attribute' to 'Month' and 'Value' to 'Sales'. This transformation is incredibly valuable for analysts dealing with survey results, financial statements, or any data presented in a wide format.

Briefly on Merging Queries: A `Power Query Merge Tables Tutorial` Concept

Merging queries in Power Query is similar to performing lookups or joins in a database. It allows you to combine two tables (queries) based on matching columns (keys).

For instance, you might have a 'SalesData' table with 'Product ID' and a 'ProductDetails' table with 'Product ID' and 'Product Category'. You could merge these to add the 'Product Category' to your 'SalesData' table.

Ensure both queries (tables) are loaded into Power Query Editor.

Select one query from the 'Queries' pane on the left.

Go to the 'Home' tab and click 'Merge Queries' (or 'Merge Queries as New' to create a new, merged table).

Select the second table and the matching column(s) from both tables.

Choose a Join Kind (e.g., Left Outer, Inner, Full Outer).

Click 'OK', then expand the new column to select which fields from the second table you want to add.

A Glimpse into Power Query M Code

Every click, every transformation you perform in the Power Query Editor is translated into a powerful scripting language known as `m language`. While you don't need to learn M to use Power Query effectively, understanding its existence is beneficial.

Viewing the M Code

You can view the `m language` code generated by your transformations by going to the 'Home' tab and clicking 'Advanced Editor'. This window shows you the exact script that defines your query. For beginners, it's a great place to appreciate the power under the hood.

While this tutorial focuses on the visual interface, exploring `power query m code examples` can open doors to more complex scenarios, such as creating `custom columns` with intricate logic, defining `parameters` for flexible reporting, or even writing custom functions.

Finalizing Your Query and Loading Data

Once you've performed all necessary transformations, the final step is to load your clean, shaped data back into Excel or the Data Model.

Close & Load Options

On the 'Home' tab of the Power Query Editor, click 'Close & Load'.

Close & Load: This is the most common option. It loads your data into a new Excel worksheet as a table.

Close & Load To...: This option gives you more control. You can choose to load the data as:

A Table in a new or existing worksheet.

Only Create Connection (useful if you're building a Data Model for Power Pivot without showing the data in a sheet).

Add this data to the Data Model (for use with Power Pivot).

Your data is now in Excel, ready for analysis, pivot tables, charts, or further reporting. The best part? Whenever your original `data source` updates, simply go to 'Data' > 'Refresh All' in Excel, and Power Query will re-run all your `applied steps`, updating your report in seconds.

Unlock Your Data's Potential with Power Query

You've just completed a foundational power query tutorial, covering how to get started, connect to data, perform essential transformations, and even tackle advanced shaping techniques like unpivoting. This powerful tool is no longer a secret weapon for data experts; it's an indispensable skill for any analyst or finance professional in 2026.

Mastering Excel Power Query M & Copilot: Clean Data & ETL 2026

Are you drowning in a sea of inconsistent spreadsheets, disparate databases, and unstructured text files? For data analysts and reporting professionals, the daily battle against messy, multi-source datasets is a persistent pain point. Manually cleaning and transforming this data is not only tedious but also highly prone to errors, undermining the reliability of your reports. But what if you could automate and optimize this entire process, ensuring pristine data quality with remarkable efficiency?

Enter Excel Power Query. This indispensable tool, combined with the power of the M language and the intelligent assistance of Microsoft Copilot, has become the ultimate solution for sophisticated data preparation. Today, we'll explore how to clean messy data in Excel Power Query, focusing on advanced techniques and best practices to transform your `excel etl with power query and copilot` workflows for 2026 and beyond.

How to Clean Messy Data in Excel Power Query: A Workflow for Analysts

Effective data cleaning is the cornerstone of accurate analysis. Without it, your insights are built on shaky ground. Power Query provides a robust environment – the Query Editor – to systematically tackle common data quality issues. Let's outline a streamlined workflow.

1. Connecting Your Data Source(s)

The first step in any `data transformation` journey is to connect to your raw `data source`. Power Query supports hundreds of sources, from Excel workbooks and CSV files to SQL Server databases, web APIs, and cloud services.

Go to the 'Data' tab in Excel.

Select 'Get Data' and choose your source (e.g., 'From File' > 'From Workbook').

Navigate to your file or provide connection details.

Load the data into the Power Query Editor.

For multi-source datasets, you'll repeat this step, bringing all necessary information into separate queries within the same Power Query instance. This lays the groundwork for later integration using `merge queries` or `append queries`.

2. Initial Data Transformation in the Query Editor

Once your data is loaded, the Power Query Editor becomes your workbench. Here, you'll perform initial cleaning steps.

Remove Rows: Eliminate blank rows, duplicate entries, or error rows.

Remove Columns: Discard irrelevant columns to simplify your dataset.

Split Columns: Break down combined data (e.g., 'First Name Last Name' into two separate columns) using delimiters or specific character counts.

Fill Down/Up: Propagate values to fill nulls, common in poorly structured reports.

Rename Columns: Ensure clear, consistent column headers.

Each action you perform is recorded as an 'Applied Step,' forming a repeatable script that can be refreshed with new data, making `excel etl` processes incredibly efficient.

3. Standardizing Data Types

Incorrect `data types` are a frequent cause of errors in analysis. Power Query automatically detects types, but it's crucial to verify and adjust them. For instance, a column containing numbers might be imported as 'Text' if it has even one non-numeric entry.

Right-click a column header and select 'Change Type' to choose the appropriate type (e.g., Whole Number, Decimal Number, Date, Text). This ensures calculations and filtering work as expected.

Power Query M Language Examples for Advanced Transformations

While the graphical user interface of the Query Editor is powerful, some complex transformations demand the precision and flexibility of the Power Query M language. M is a functional language that underpins every action you perform in Power Query. Learning even a little M can dramatically expand your capabilities.

1. Custom Columns with M

M allows you to create highly dynamic custom columns that go beyond simple arithmetic.

if [Sales] > 1000 then "High" else "Low"

This simple `Power Query M language examples` demonstrates conditional logic to categorize sales figures. You can also combine text, extract parts of dates, or perform complex lookups.

2. Conditional Logic and Error Handling

M's try...otherwise structure is invaluable for robust `data transformation` workflows, preventing query breaks due to dirty data.

try Number.FromText([AmountText]) otherwise null

This code attempts to convert a text column to a number. If it fails (e.g., due to non-numeric characters), it returns null instead of an error, allowing your query to proceed.

3. Leveraging Functions for Reusability

M `functions` allow you to encapsulate complex logic into reusable blocks. If you have a custom cleaning step you apply to multiple tables or columns, creating a function saves time and ensures consistency. For example, a function to clean specific text patterns can be called across various columns.

Leveraging Microsoft Copilot for Enhanced Excel ETL

As of 2026, Microsoft Copilot has integrated deeply with Excel, bringing AI assistance directly into your `excel power query` workflows. This is a game-changer for speeding up data preparation, especially for those less familiar with intricate M code.

1. Generating M Code with Copilot

Instead of manually clicking through transformations or writing M from scratch, you can simply describe what you want to achieve using natural language. For instance, you could prompt Copilot:

'Generate Power Query M code to unpivot all columns except 'Date' and 'Region', then rename the 'Attribute' column to 'Metric' and 'Value' column to 'Amount'.'

Copilot will then suggest the appropriate M code, which you can review and apply, significantly accelerating development and helping you learn `power query m` in context.

2. Explaining Complex Queries and Troubleshooting

Have you inherited a complex Power Query with dozens of applied steps and custom M code? Copilot can analyze the query and provide plain-language explanations of what each step does. It can also help identify potential errors or inefficiencies in your existing `power query copilot` solutions, making troubleshooting much faster.

3. Automating Repetitive Tasks

Copilot can learn from your typical `data transformation` patterns. If you frequently perform a sequence of cleaning steps, Copilot can suggest automating these steps in future queries or even help build `parameters` to make your queries more flexible and dynamic.

Reshaping Data with Pivot/Unpivot and Other Techniques

Beyond basic cleaning, `excel power query` excels at reshaping data to fit analytical requirements. Two powerful features for this are Pivot and Unpivot.

1. `Pivot Unpivot` in Practice (`power query pivot and unpivot examples`)

Unpivot: Transforms columns into rows. This is essential when your data has metrics spread across multiple columns (e.g., 'Sales Q1', 'Sales Q2', 'Sales Q3'). Unpivoting converts these into two columns: 'Quarter' and 'Sales Value', making the data 'tall' and suitable for aggregation.

Pivot: Does the opposite, transforming rows into columns. Useful for summarizing data, like showing total sales for each product as columns with regions as rows.

These operations are easily accessible from the 'Transform' tab in the `Query Editor` and are critical for preparing data for reporting tools or pivot tables.

2. Combining Datasets: `Merge Queries` and `Append Queries`

When working with `multi-source datasets`, you often need to combine information. Power Query provides two primary methods:

Merge Queries: Joins two tables based on a common key (like a customer ID or product code), adding new columns from one table to another. Think of it like a VLOOKUP or a SQL JOIN.

Append Queries: Stacks one table on top of another. This is used when you have identical data structures from different periods or regions that you want to consolidate into a single list.

Understanding when to use each is fundamental for effective `excel etl` with multiple `data source` connections.

Best Practices for Robust Power Query Workflows

To ensure your `excel power query` solutions are maintainable, efficient, and reliable, adopt these best practices:

1. Structure Your Queries Logically

Group related queries into folders. Use descriptive names for queries and applied steps. A well-organized `Query Editor` is easier to understand and debug.

2. Use `Parameters` for Flexibility

Instead of hardcoding values (like file paths or filter dates), use `parameters`. This allows you to change inputs without modifying the core query logic, making your solutions more adaptable for different reporting periods or scenarios.

3. Document Your Work

Add comments to complex M code or particularly tricky applied steps. A simple `// This step cleans XYZ` can save hours of confusion later, especially when collaborating or reviewing older queries.

4. Test Incrementally

After each major transformation, inspect your data to ensure the step worked as intended. Don't wait until the very end to check for errors; catch them early.

Mastering `excel power query` combined with the depth of the M language and the intelligence of Microsoft Copilot isn't just about cleaning data; it's about building scalable, reliable, and intelligent data pipelines. For data analysts and reporting professionals grappling with the complexities of modern datasets, these skills are no longer optional—they are essential for driving accurate insights and efficient workflows.

'Explain what this formula does: =INDEX(MATCH()).'

'Suggest improvements to the data structure in 'Raw_Data' for better analysis.'

Real-World Workflow: Streamlining a Monthly Report

Let's illustrate how excel copilot can dramatically streamline a common, advanced workflow: preparing a monthly sales performance report. This mini case study shows the practical application of Copilot.

Step 1: Data Import and Cleaning

You begin with raw sales data from various sources. Instead of manual cleanup, you can prompt Copilot: 'Clean this data by removing duplicate entries and standardizing text in the 'Product Name' column.' Copilot will suggest and apply the necessary Power Query transformations or formulas.

Step 2: Formula Generation and Data Analysis

Next, you need to calculate key metrics. You use Copilot to generate complex formulas:

'Calculate the Gross Profit Margin for each transaction (Sales Price - Cost / Sales Price).'

'Use XLOOKUP to pull customer segment data from the 'Customer_CRM' sheet into the main sales data.'

'Create a Dynamic Array formula to list all products that saw a sales increase greater than 10% month-over-month.'

Copilot handles the syntax, populating your spreadsheet with accurate calculations quickly.

Step 3: Creating Interactive Reports

Now, to visualize the data, you engage Copilot:

'Generate a PivotTable showing total sales by region and product line, with a filter for the current month.'

'Create a clustered column chart comparing monthly sales targets against actuals.'

'Apply conditional formatting to highlight any region that did not meet its sales target in red.'

Within minutes, Copilot builds the interactive report elements, ready for presentation.

Step 4: Iteration and Refinement

Your manager asks for a specific drill-down. Instead of rebuilding, you use Copilot: 'Show me the top 5 customers by revenue in the 'East' region for last month.' Copilot quickly refines the existing PivotTable or generates a new summary, enabling rapid iteration and deeper insights without starting from scratch. This entire process, which might have taken hours or even days, is compressed into a fraction of the time, demonstrating true spreadsheet automation.

Beyond Formulas: Spreadsheet Automation and Deeper Insights

The capabilities of excel copilot extend beyond mere formula generation and PivotTable creation. It's a powerful tool for broader spreadsheet automation and unlocking deeper insights from your data using natural language.

Automating Repetitive Tasks

Think about repetitive data manipulation tasks you perform every month. Copilot can learn from your actions or respond to specific instructions to automate these. For instance, you could instruct Copilot to 'Sort this entire workbook by 'Date' column in ascending order, then filter for 'Completed' status' across multiple sheets. This level of automation significantly boosts efficiency and reduces the chance of human error in your data analysis.

Uncovering Deeper Insights with Natural Language

One of Copilot's most compelling features is its ability to understand complex questions posed in natural language and provide insightful answers directly from your data. You can ask, 'What factors contributed most to the sales decline in Q1?' or 'Identify any correlations between customer age and product preference.' Copilot will analyze your data, identify patterns, and present its findings, often suggesting further explorations or visualizations.
