A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Try these steps on the Mac, in order:
- Check whether Excel is in reduced functionality mode.
- Starting July 13, 2026, Office apps on macOS can open and print files but cannot edit, save, or create new files if the app is in reduced functionality mode.
- If that applies, update Microsoft 365 or Office on the device.
- Refresh Excel file and folder permissions in macOS.
- Quit Excel completely with Excel > Quit Excel or Command + Q.
- Open Apple menu > System Settings > Privacy & Security > Files and Folders.
- Find Microsoft Excel and turn on access to available locations, especially Documents, Desktop, and Downloads.
- If access is already on, turn one permission off and back on.
- Restart the Mac and test in a blank workbook.
- If Excel is not listed there, open an existing workbook from Documents or Desktop and allow the macOS permission prompt.
- Remove Excel preference files.
- Quit all Office for Mac apps.
- In Finder, select Go > Home > Library > Preferences.
- If Library is hidden, hold Option while opening the Go menu.
- Drag com.microsoft.Excel.plist to the desktop.
- Open Excel and test.
- If the issue remains, restore that file, then go back to Home > Library > Preferences > Microsoft and drag com.microsoft.Excel.prefs.plist to the desktop.
- Open Excel and test again.
- If one of these fixes the issue, move the affected preference file to Trash.
- Test with a new macOS user account.
- Open Apple menu > System Preferences > Accounts.
- Select + to create a new account.
- Create a test account, sign out, then sign in with that new account.
- Open Excel and test typing in a blank workbook.
- If Excel works there, the original macOS user profile is likely corrupted.
- Reinstall Office if the problem continues.
- Corrupted application files can prevent Excel from working correctly.
- Remove Office, then reinstall it.
If Excel opens but still will not let anything be entered, the most likely causes in the available guidance are macOS permission issues, corrupted Excel preferences, a corrupted user profile, or reduced functionality mode.
