A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Try these steps in order:
- Restart Windows, then try Excel again.
- Start Excel in Safe Mode to check whether an add-in or startup item is blocking it:
- Press Windows + R
- Type
excel /safe - Press Enter
- If Excel opens in Safe Mode, the issue is likely caused by something Excel loads at startup.
- Check Excel startup folders, because a workbook in one of these folders can stop Excel from opening correctly.
- For the XLStart folder:
- Open File > Options > Trust Center > Trust Center Settings > Trusted Locations
- Note the XLStart path
- Move any files from that folder to another folder
- Start Excel normally
- For an alternate startup folder:
- Open File > Options > Advanced
- Under General, check At Startup, open all files in
- Move any files from that folder to another folder
- Start Excel normally
- If Excel works after that, move the files back one at a time to find the file causing the problem.
- For the XLStart folder:
- Repair Office.
- In Windows 10/11: right-click Start and open Installed apps or Apps and Features
- Select Microsoft Office or Microsoft 365
- Choose Modify
- First try Quick Repair
- If that does not fix it, run Online Repair
- If Excel opens only in Safe Mode, disable add-ins:
- In Excel, go to File > Options > Add-ins
- At the bottom, choose COM Add-ins in Manage
- Select Go
- Clear the add-ins, then restart Excel normally
Note: Online Repair repairs the full Office suite and can take longer, but it is more thorough than Quick Repair.
