Power BI DAX with AI is transforming the way analysts and business users write formulas. Instead of memorizing syntax, you can now describe your logic in plain English—and Copilot will do the rest.
What Is Power BI DAX with AI?
DAX (Data Analysis Expressions) is the formula language behind advanced reporting and calculations in Power BI. It powers custom measures, KPIs, calculated columns, and more. But mastering DAX isn’t easy—especially for non-developers.
Microsoft introduced Copilot to help bridge this gap. Using artificial intelligence, you can now instruct Power BI to create DAX measures using intuitive language and let Copilot generate, explain, and even refine those formulas instantly.
Why Use AI for Writing DAX?
- Accessibility: Even users without DAX experience can build powerful logic.
- Speed: Generate complete formulas in seconds instead of hours.
- Error Reduction: Copilot helps eliminate common syntax problems or logic errors.
- Learning: Ask Copilot to explain code, improving your personal understanding of DAX functions.
Step-by-Step: How to Use Power BI DAX with AI
- Enable Copilot:
- Go to File > Options > Preview Features
- Enable “DAX query view with Copilot”
- Restart Power BI Desktop
- Open DAX Query View (the fourth icon on the left sidebar)
- Launch Copilot by pressing
Ctrl + Ior clicking the Copilot icon - Type your prompt:
“Create a DAX measure for total sales this year by store and category.” - Review and apply the code: Click Run and then Keep query to save it
Real Example: Rolling Average in Just One Prompt
Prompt Copilot with:
“Show 3-month rolling average of SalesAmount by month.”Copilot returns DAX like this:
DEFINE
MEASURE 'Sales'[3M Rolling Avg] =
AVERAGEX(
DATESINPERIOD('Date'[Date], LASTDATE('Date'[Date]), -3, MONTH),
[Total Sales]
)
EVALUATE
SUMMARIZECOLUMNS(
'Date'[Month],
"3M Rolling Avg", [3M Rolling Avg]
