A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
The spreadsheet opening as view-only usually means Excel is not properly activated or signed in with the account that owns the license.
Try these steps on the Mac:
- Confirm Excel/Office activation
- Open another Office app (for example, Word or PowerPoint) that currently works.
- Check if it shows as activated and which account is signed in.
- If Excel alone is failing activation or licensing, this can indicate a Mac-specific licensing issue.
- Check for known Excel for Mac issues
- Review the “Fix and workarounds for recent Excel issues for Mac” article to see if there is a known issue affecting activation or file editing on Mac and apply any listed workaround.
- If Excel licensing looks broken only for Excel
- Follow the general Excel troubleshooting guidance (for example, repairing or reinstalling Office for Mac) as suggested in the Excel troubleshooting and support content.
- If reinstalling is needed, use the official Office for Mac install/uninstall guidance referenced from the Excel for Mac troubleshooting article.
- If still stuck and support is hard to reach
- Use the guided support for Excel issues, which can walk through activation and file-editing problems and provide a direct path to support.
- If Outlook for Mac is installed and working, the in-app Help > Contact Support option (described for Outlook) can be used as a model for contacting Microsoft support from within Office apps on Mac.
If none of these steps resolve the view-only state, contacting Microsoft Support directly (for example, via the Excel guided support or general Microsoft 365 support entry points) is required so they can check the account and subscription status behind the scenes.
