Excel has run into an error that is preventing it from working correctly. excel will need to be closed as a result

Hi, Shankar Giri

This error usually means Excel is starting with something it doesn’t like, most often an add-in, a startup file, or another program in Windows getting in the way. If it opens in Safe Mode, that’s a strong sign the core app is fine and the problem is around it, not the workbook itself.

Besides the solutions provided by the Q&A Assist, here are some suggestions you can try:

Open Excel in Safe Mode first, press Windows + R, type excel /safe, and see if it opens. If it does, go to File > Options > Add-ins, disable the COM Add-ins, then re-enable them one by one until you find the one causing the crash.

Check Excel’s startup folders too. Files in XLSTART or an alternate startup folder can make Excel crash on launch, so move those files out temporarily and test again.

Make sure both Office and Windows are fully updated. There are crash and add-in related fixes in newer Excel builds.

If it still happens, try a clean boot and temporarily turn off any antivirus integration with Excel. It is suggested that background services, antivirus plug-ins, printer drivers, or video drivers can also trigger this kind of crash.

Thank you for your patience in reading, I hope this information has been helpful to you.

Use the following steps to fix the error “Excel has run into an error that is preventing it from working correctly. Excel will need to be closed as a result” on Windows and Microsoft 365/Office:

1. Close all Office apps

• Make sure Excel, Word, Outlook, and any other Office apps are closed before starting.

2. Run an Online Repair of Office
3. Open Settings in Windows.
4. Go to Apps → Installed apps.
5. Find Microsoft 365 (or Office) in the list.
6. Select the three dots (…) → Modify.
7. Choose Online Repair and confirm.
8. Let the repair complete (this can take 15–30 minutes). Do not cancel it.
9. Restart the PC after the repair finishes.
10. Open Excel first and check if it now works normally.

This process reinstalls Office components and fixes corrupted files that commonly cause this error across all Office apps.

If the error persists even after Online Repair, a full uninstall of Office, removal of leftover Office folders and registry entries, and then reinstalling Office has been reported to resolve similar persistent errors.
