Frequently Asked Questions

Why is the Copilot button missing from my Excel ribbon?

The Copilot button may not appear if you do not have an active Copilot for Microsoft 365 license, your organization has restricted access, or your file is saved locally instead of on OneDrive or SharePoint.

Do I have to format my data as a table to use Copilot?

Yes, Copilot in Excel requires your data to be formatted as an official Excel Table (using Ctrl+T or Insert > Table) to accurately identify headers, analyze the dataset, and generate insights.

Can Copilot group my sales data by month instead of by quarter?

Yes. You can easily adjust your analysis by changing the prompt in the Copilot pane to: "Show sales by month based on the release date." Copilot will update the PivotTable and PivotChart accordingly.
