If you’ve been using Power BI for your business dashboards, you already know it’s one of the most powerful reporting tools available. But what if you could supercharge your Power BI workflow with ChatGPT? The combination of these two tools can save you hours every week — from writing DAX formulas to building entire report layouts faster than ever.

Whether you’re a seasoned Power BI developer or just getting started, here are five practical ways ChatGPT can transform how you work with Power BI in 2026.

1. Let ChatGPT Write Your DAX Formulas

DAX (Data Analysis Expressions) is the formula language behind Power BI’s calculations. It’s powerful, but the syntax can be tricky — especially for complex measures involving time intelligence, filtering, or iterators.

Instead of spending 20 minutes debugging a CALCULATE function, try describing what you need in plain English to ChatGPT. For example, you might say: “Write a DAX measure that calculates year-over-year revenue growth as a percentage, comparing the current month to the same month last year.”

ChatGPT will generate the formula, explain how it works, and even suggest variations. You can then paste it directly into Power BI Desktop. This alone can cut your development time in half for complex reports.

2. Generate Sample Data for Prototyping Dashboards

Need to build a demo dashboard but don’t have real data yet? ChatGPT can create realistic sample datasets in seconds. Ask it to generate a CSV with columns like sales date, region, product category, revenue, and quantity — and it will produce structured data that’s ready to import into Power BI.

This is especially useful when you’re pitching a dashboard design to stakeholders or teaching Power BI concepts in a training session. You get a working prototype without waiting for actual data extracts.

3. Build Power Query M Code with Natural Language

Power Query is where you clean and transform data before it reaches your report. The M language that powers it can feel intimidating, particularly when you need custom transformations like conditional column logic, date parsing, or merging tables with complex join conditions.

ChatGPT handles M code generation extremely well. Describe your transformation step — “Remove duplicate rows based on the CustomerID column, keeping only the most recent order date” — and get clean, working M code in return. This makes data preparation significantly faster and reduces errors from manual coding.

4. Create Report Documentation Automatically

One of the most overlooked parts of any BI project is documentation. When your reports grow complex with dozens of measures, calculated columns, and data sources, it becomes critical to have clear documentation — both for your own reference and for anyone who inherits the project.

Copy your DAX measures or data model details into ChatGPT and ask it to generate documentation. It can produce a structured summary that includes each measure’s purpose, the tables and columns it references, and any dependencies. You can even ask it to format the output as a table for easy pasting into a Word document or wiki page.

This turns a task that normally takes hours into a 10-minute process.

5. Troubleshoot Performance Issues with AI-Assisted Analysis

Slow Power BI reports are a common frustration. The causes can range from inefficient DAX queries to oversized data models to poorly optimized visuals. Diagnosing these issues typically requires deep expertise in the Performance Analyzer and DAX Studio.

ChatGPT can help you interpret performance data. Paste the results from Power BI’s Performance Analyzer into a chat, and ask ChatGPT to identify bottlenecks. It can suggest specific optimizations like replacing calculated columns with measures, simplifying FILTER contexts, or restructuring your data model for better performance.

While it won’t replace a dedicated BI consultant for enterprise-level optimization, it’s an excellent first line of defense for everyday performance tuning.

Bonus: Use ChatGPT to Prepare for Power BI Certification

If you’re studying for the PL-300 (Microsoft Power BI Data Analyst) certification, ChatGPT makes an excellent study partner. It can quiz you on DAX concepts, explain the differences between import and DirectQuery modes, and walk you through practice scenarios. Pair it with official Microsoft Learn modules and you’ll be well-prepared for the exam.

Getting Started Today

The best part about combining ChatGPT with Power BI is that there’s no setup required — no plugins to install, no API keys to configure. Just open ChatGPT in one browser tab and Power BI Desktop on your screen, and start asking questions as you build.

Start with one of the tips above and see how much time it saves you this week. Once you experience the productivity boost firsthand, you’ll never want to work without it.
