Hi, I'm Bernard. I'm happy to help!

Kindly follow the steps provided by Q&A Assist. If the issue persists, I recommend reinstalling the Office app by following the steps below:

Step 1. Uninstall Office app:

Press the Windows key + R, then type in:

 

appwiz.cpl

 

Then hit OK> Look for the Microsoft Office or Microsoft 365 app > Right-click, then select Uninstall and follow the prompts to uninstall.

Step 2. Reinstall the Office app:

Download and install your Office app by following the steps from the link below:

Use the full Office repair tools and Excel-specific troubleshooting to fix this.

1. Try a full Online Repair of Office (Windows 11)
   1. Close all Office apps (Excel, Word, Outlook, etc.).
   2. Right-click the Start button and select Installed apps.
   3. Find Microsoft 365 or Office in the list.
   4. Click the … (ellipses) next to it and choose Modify.
   5. In the repair window, select Online Repair > Repair and confirm.
      • This fully reinstalls Office and replaces corrupted components.
   6. Wait for the repair to complete, then restart Windows.
   7. Open Excel again and test.
2. If Excel still will not open, start Excel in Safe Mode
   1. Press Windows key + R.
   2. Type Excel /safe and select OK.
   3. If Excel opens in Safe Mode, the issue is likely add-ins:
      1. Select File > Options > Add-ins.
      2. At the bottom, set Manage to COM Add-ins and select Go.
      3. Clear all check boxes, select OK, then close Excel.
      4. Open Excel normally (not in Safe Mode).
      5. If Excel now works, re-enable add-ins one by one, restarting Excel each time, until the problem add-in is found.
3. If Excel does not start even in Safe Mode
   • After confirming Safe Mode also fails, repeat the Online Repair step above to ensure all Office files are repaired.

If the problem persists after Online Repair and Safe Mode/add-in checks, contact Microsoft Support, as a deeper removal and reinstall (using the Office uninstall tool) may be required.
