Explain a formula

Use Copilot in the formula bar to understand what a formula is doing.

1. Select a control and its corresponding property.

2. On the formula bar, select the Copilot functionality menu > Explain This Formula.

   When Copilot provides an explanation of the formula, you can copy and insert it as a code comment or share it with other makers who are working on the same app.

Known Limitations

• There's a 5,000 character limit for formula explanations.
• Copilot in Power Apps is only aware of default properties.
• User defined functions aren't supported.

Copilot comment generated formulas (preview)

[This section is prerelease documentation and is subject to change.]

When you add a comment in the formula bar, Copilot will provide a suggested formula. You have the option to accept the suggestion or manually type the formula. These comments can serve as documentation in the formula bar, just like regular code comments.

1. With your canvas app open for editing, type a code comment using // or /* in the formula bar.

   Wait few seconds for Copilot to generate a formula recommendation or press enter to generate immediately.

2. Use the Tab key on the keyboard to select and use the recommended formula. You can also type through the recommendation.

   The suggested formula remains until you select elsewhere or type a character that doesn't align with the recommendation. You can keep comments used for generating Power Fx formulas in the formula bar as documentation, similar to traditional code comments.

Note

• If Copilot doesn't provide a suggestion, it couldn't generate a formula based on your comment. Try rephrasing or modifying the comment.
• We recommend, enclosing the element you want to incorporate in your formula within quotes such as "Button1.text".

Known Limitations

• Copilot in Power Apps only recognizes the default properties within the app.
• Code comments only work with general Power Fx functions, and not Power Apps specific functions such as Navigate().
• The advanced panel doesn't trigger suggestions.
• Existing formulas for that property aren't included in the recommendation.
• User defined functions aren't supported.
• This feature isn't available in the Canada region.

Enable or disable Copilot comment generated formulas

Copilot comment generated formulas are enabled by default for new apps, and disabled by default for existing apps, but can be enabled or disabled for any app from app settings.

• Go to Settings > Upcoming features. Set the toggle to On or Off for Copilot comment-generated formulas.

Note

When Copilot comment generated formulas is fully integrated into the platform and generally available, it won't be possible to disable it.
