A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Start Excel in Safe Mode; if it opens, disable its add-ins, and if it still does not open, run an Online Repair of Microsoft 365 or Office.
1. Test Excel in Safe Mode
- Press Windows key + R.
- Type the following command, including the space before
/safe:
excel /safe
- Select OK.
- Check whether the title bar shows Microsoft Excel (Safe Mode). Safe Mode starts Excel without most add-ins and startup customizations, helping identify whether one is preventing startup.^1^
2. If Excel opens in Safe Mode
Disable the add-ins:
- In Excel, select File → Options → Add-ins.
- At the bottom, set Manage to COM Add-ins, then select Go.
- Clear all checkboxes and select OK.
- Close Excel and open it normally.
- If Excel now opens, re-enable the add-ins one at a time, restarting Excel after each one, to identify the problematic add-in.^2^
3. If Excel does not open in Safe Mode
Repair the Office installation. This repairs the entire Office suite, even when only Excel is affected.^3^
Windows 11
- Right-click Start → Installed apps.
- Find Microsoft 365 or Microsoft Office.
- Select the three dots → Modify.
- Choose Online Repair → Repair.
- Complete the repair, restart the laptop, and try Excel again.
Windows 10
- Right-click Start → Apps and Features.
- Select Microsoft 365 or Microsoft Office → Modify.
- Choose Online Repair → Repair.
- Complete the repair, restart the laptop, and try Excel again.
Online Repair is more thorough than Quick Repair. If your installation only displays an MSI repair option, select Repair → Continue instead.^3^
If Excel remains completely unresponsive after Online Repair, provide the Windows version, Office version, and whether excel /safe displayed an error such as “Windows cannot find Excel.” Those details determine the next appropriate installation or startup troubleshooting step.
