A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Use an Online Repair of Office to fix this error, as it indicates corrupted Office/Excel components.
Follow these steps:
- Close all Office apps (Excel, Word, Outlook, etc.).
- Open Settings in Windows.
- Go to Apps → Installed apps.
- Find Microsoft 365 (or Office) in the list.
- Select the three dots (…) → Modify.
- Choose Online Repair and confirm.
- Let the repair run to completion; it can take 15–30 minutes.
- Restart the PC after the repair finishes.
- Open Excel and verify that it starts and works normally.
If the problem persists across all Office apps even after Online Repair, completely uninstall Office from Apps & Features/Installed apps, remove any remaining Office folders and related registry keys as described in the referenced guidance, restart the computer, and then reinstall Microsoft 365.
