Mastering Power BI Custom Q&A: A Complete Guide to Natural Language Queries
October 28 2025
Have you ever looked at a Power BI dashboard and thought, “I just want to ask a question and get the answer—no clicks, no filters”? That’s exactly what Power BI’s Q&A feature delivers. But here’s the real game-changer: Custom Q&A in Power BI.
In this blog, we’re not just scratching the surface. You’ll learn how to go beyond default settings and actually train Power BI to understand the way your business talks. Whether it’s syncing jargon with your data model, creating tailored phrasings, or fine-tuning how visuals respond to natural queries, this blog gives you everything you need to turn Q&A into a powerful self-service BI tool.
Let’s dig in.
What Is Power BI Q&A and Why Does It Matter?
Power BI Q&A is a native feature that allows users to ask questions using plain English (or other supported languages). When a user types a query like:
“What are the total sales this quarter by region?”
Power BI uses natural language processing (NLP) to interpret the question, analyze the data model, and instantly generate the most relevant visual—like a bar chart, line graph, or table.
How It Works
Power BI Q&A works by:
- Parsing user intent through NLP
- Mapping keywords to datasets, fields, and measures
- Generating visuals using AI-driven suggestions
It’s built for speed, simplicity, and natural data exploration, but the quality of the response hinges on the strength of your underlying data model—and that’s where customization steps in.
Why Customize the Q&A Feature in Power BI?
While Power BI Q&A is impressive out of the box, its true potential is only unlocked when tailored to your business language and structure.
Key Benefits of Power BI Custom Q&A
- Improved Accuracy: Get better results by guiding the tool with synonyms, phrasing rules, and hidden fields.
- Business Relevance: Align queries to your company’s specific metrics and terminology.
- User Accessibility: Enable business users (not just data analysts) to interact with data intuitively.
- Time Savings: Reduce back-and-forth between report creators and stakeholders.
Common Issues Solved by Custom Q&A
| Problem | Solution |
| Users ask using abbreviations like “YOY” | Add synonyms and define phrases |
| The system returns irrelevant tables | Hide helper/system fields |
| Queries misunderstand industry terms | Train Q&A with domain-specific phrases |
| Stakeholders can’t find the right visual | Use predefined Q&A suggestions |
How to Set Up Custom Q&A in Power BI: Step-by-Step
Ready to teach Power BI your business language? Here’s how to get started.
1. Prepare Your Data Model
Before setting up Q&A, make sure your dataset is:
- Well-organized
- Uses clear and business-friendly field names
- Properly categorized (e.g., Date, Currency, Text)
2. Add a Q&A Visual to Your Report
- Go to the Report View in Power BI Desktop.
- Insert a Q&A visual from the Visualizations pane.
- Power BI will auto-generate a few sample questions to get started.
3. Configure Custom Q&A Settings
Click the ellipsis (…) on the Q&A visual > Choose “Settings” or “Teach Q&A”. You can now:
A. Add Synonyms
Map different terms users might use to your data fields.
- Example: “income”, “revenue”, and “topline” → Sales Amount
B. Define Custom Phrasings
Teach Power BI how to respond to specific questions.
- Example: “Top-performing agents” = “Top 5 agents by total revenue”
C. Hide Irrelevant Fields
- Hide technical fields, calculated columns, or temporary tables that might confuse Q&A.
D. Suggest Sample Questions
Pre-populate sample queries that guide users on what to ask.
- Great for self-service BI onboarding.
Real-World Example: Q&A Customization in Action
Let’s say your marketing team wants quick access to campaign performance but uses different terms than those in your data model.
Scenario:
- User types: “Top 3 performing campaigns last month”
- Dataset field: Campaign_Name, Conversion_Rate, Month
Without Custom Q&A:
The system might return an error or irrelevant chart.
With Custom Q&A:
- You define a phrase: “performing campaigns” = campaigns ranked by conversion rate
- You set synonyms: “last month” → dynamic date filter
- You hide unnecessary tables like lookup lists or staging tables
Now the team gets a perfect bar chart every time—no training needed.
Best Practices for Custom Q&A in Power BI
To make your natural language queries in Power BI more effective:
1. Use Descriptive Field Names
Replace “SalesAmt” with “Sales Amount” for better readability.
2. Maintain a Business Glossary
Keep a list of internal jargon and standard business terms for consistent mapping.
3. Continuously Train the Q&A Model
Use the “Teach Q&A” interface to review, accept, or improve user-asked questions.
4. Gather Real Questions from Stakeholders
Build your Q&A phrasing around how people actually ask questions in meetings.
5. Limit Noise in Your Data Model
Fewer irrelevant fields = better and faster results.
Power BI Q&A vs Other Query Methods
| Method | Skill Needed | Speed | Best For |
| Manual Filtering | Basic | Moderate | Known report structures |
| DAX Measures | Advanced | Fast | Advanced analytics |
| Q&A (Default) | Beginner | Fast | Casual exploration |
| Q&A (Custom) | Beginner | Very Fast | Business-specific insights |
Takeaway: Power BI Custom Q&A Unlocks Natural Self-Service Analytics
By customizing Power BI Q&A, you give users a natural language gateway to data. No need to click through reports, memorize field names, or request help from analysts. With the right setup, Power BI becomes a conversation partner—one that speaks your business’s language.
And that’s the future of self-service BI.
