Meet Copilot in Power BI

Copilot is Microsoft's AI assistant built directly into Power BI. Instead of clicking through menus and writing formulas, you type what you want in a chat box and Copilot does it: it builds report pages, writes DAX measures, cleans data, and summarizes what your report is telling you. Think of it as a knowledgeable analyst sitting next to you who never gets tired of your questions.

In this lesson you will learn what Copilot can actually do, where the chat box lives, how to write requests it understands, and, importantly, what to do if you do not have access to Copilot yet. Spoiler: you can complete this entire course without it by using free assistants, so no one gets left behind.

What You'll Learn

• The specific things Copilot in Power BI can do for you
• Where Copilot appears and how you talk to it
• How to write a Copilot request that gets a good result
• What to do if you do not have paid Copilot access yet

What Copilot Can Do Inside Power BI

Because Copilot can see your loaded data model, table names, and columns, it can do things a browser assistant cannot:

Build report pages. Type "Create a page summarizing sales by region and product category with a trend over time" and Copilot assembles the visuals for you to refine.

Write DAX measures. Ask "Create a measure for year-over-year revenue growth as a percentage" and it writes the DAX referencing your actual tables.

Clean and prepare data. In Power Query, Copilot can suggest transformation steps, describe what a query does, and even generate steps from a description.

Summarize your report. Copilot can write a plain-language narrative of what a page shows: "Revenue grew 12% quarter over quarter, driven by the West region."

Answer questions about your data. Ask "Which month had the highest returns?" and it responds using your model.

The theme is speed. Copilot does not replace your judgment; it removes the slow, fiddly typing so you can spend time thinking about the answer instead of the syntax.

Where Copilot Lives

In Power BI Desktop and the Power BI web service, Copilot appears as a button (often on the Home ribbon) that opens a chat pane on the right side of the screen. You type a request, Copilot proposes an action or result, and you accept, edit, or reject it. In Power Query, Copilot appears as a similar assistant for data-cleaning steps.

Copilot requires your organization to have a Fabric capacity or Power BI Premium, and an admin usually has to switch it on. That is why many students, especially those on a personal or student account, will not see the button yet. This is completely normal and not a problem for this course.

How to Talk to Copilot

Copilot is only as good as your request. A vague prompt gives a vague result. Use this simple recipe: say what you want, name the fields, and give the context.

Weak request:

"Make a sales page."

Strong request:

"Create a report page titled 'Sales Overview' with: a card showing total Revenue, a line chart of Revenue by Month, a bar chart of Revenue by Region, and a table of the top 10 Products by Revenue. Use the Sales and Products tables."

The strong version names the visuals, the fields, and the tables, so Copilot has no guesswork to do. You will get a page that is 90% of the way there, and you finish it in minutes.

The same principle applies to measures:

"Write a DAX measure named 'Revenue YoY %' that calculates the percentage change in total Revenue versus the same period last year, using the Date table for time intelligence."

No Copilot Access? Here Is Your Plan

If you do not have Copilot, you will use free browser assistants for the same jobs. The trick is that you feed the assistant the context Copilot would have seen automatically. Open ChatGPT, Claude, or Gemini in a tab and paste your table and column names first. For example:

"I'm building a Power BI report. My data model has these tables and columns:

• Sales: OrderDate, Region, ProductID, Quantity, Revenue
• Products: ProductID, ProductName, Category
• Date: Date, Month, Year

Write a DAX measure named 'Revenue YoY %' for the percentage change in total Revenue versus the same period last year. Explain where to paste it."

You will get the exact same DAX, plus a short explanation, and you paste it into Power BI's measure editor yourself. Throughout this course, every Copilot task has a free-tool equivalent like this. You lose a little automation and gain a habit that makes you a stronger analyst, because you learn to describe your model clearly.

Try It Now

Even without Power BI open, practice the request-writing skill. Pick any free assistant and paste this:

"I have a Power BI table called Orders with columns OrderDate, CustomerID, Region, and Amount. In plain English, list five useful measures a beginner should create for a sales dashboard, and for each one write the DAX. Keep explanations to one sentence each."

Read the five measures. Notice how the AI turned a fuzzy goal ("useful measures") into concrete, pasteable formulas. That translation, from goal to formula, is the core skill this course builds.

A Word on Trust

Copilot and free assistants both make mistakes. Copilot might build a chart with the wrong aggregation; ChatGPT might invent a column name you never gave it. Always check that:

• Measure names and column names match your real model
• The numbers look reasonable (does total revenue match what you expect?)
• The chart answers the question you actually asked

If something looks off, tell the AI what is wrong and ask it to fix it. AI is happy to iterate, and iterating with it is often faster than starting over.

Key Takeaways

• Copilot is an AI assistant built into Power BI that builds pages, writes DAX, cleans data, and summarizes reports using your real model.
• You talk to Copilot in a chat pane; the quality of your result depends on how clearly you state the fields, visuals, and context.
• Copilot needs a paid Fabric or Premium capacity, so many beginners will not have it, and that is fine.
• Without Copilot, paste your table and column names into a free assistant and get the same DAX and cleaning help.
• Always verify names and numbers; both Copilot and free assistants can be confidently wrong.
