A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Copilot cannot be manually added as an Excel add-in. It appears automatically when the signed-in account, subscription, and organization settings provide access.
Besides the solutions provided by the Q&A Assist, here are some suggestions you can try:
Open https://www.microsoft365.com/launch/excel and sign in with the account that owns your Microsoft 365 subscription. If Copilot appears there, the license is working and the issue is limited to the desktop installation.
In desktop Excel, select File > Account and confirm the email under User Information is the same account that owns the subscription. Sign out any old, work, school, or personal accounts that may be taking priority, then restart Excel.
On Windows, open the Get Help app, search for Copilot License Troubleshooter, and run it. This checks whether Excel can detect the Copilot entitlement.
If this is a company or school account, ask the Microsoft 365 administrator to confirm Copilot is assigned to your exact user account. After a new assignment, it may take up to 24 hours to appear.
Also note that one-time-purchase versions of Office may not include Copilot. Copilot availability depends on an eligible Microsoft 365 subscription.
