How to Fix Microsoft Excel Crashing on Windows 11: Step-by-Step Solutions

Microsoft Excel is one of the most widely used spreadsheet applications worldwide. However, it can sometimes crash unexpectedly on Windows 11, causing frustration and loss of work. This article will guide you through simple and effective steps to fix Excel crashing issues.

Whether Excel crashes on startup, while opening files, or during regular use, these solutions will help you identify and resolve the problem. The instructions are designed to be easy to follow, even for users with minimal technical experience.

By following these steps carefully, you can restore Excel’s stability and improve your overall productivity. Let’s begin with some quick checks before diving into troubleshooting.

These methods range from basic fixes to more advanced options, so you can try them one by one until the issue is resolved.

Quick Note: Before You Begin

Save your work regularly: Crashes can cause data loss, so keep backups of important Excel files.
Check for Windows updates: Updating Windows ensures compatibility and may fix system bugs affecting Excel.
Ensure Excel is updated: Microsoft frequently releases updates that improve stability and security.
Close other applications: Running many programs at once can overload your system and cause Excel to crash.

Step 1: Restart Your Computer

Sometimes, the simplest step is the most effective. Restarting your computer clears temporary files and frees up system resources. This can resolve conflicts causing Excel to crash.

Click the Start menu.
Select the power icon.
Choose “Restart” and wait for your PC to reboot.
Open Excel again to check if the issue persists.

Step 2: Start Excel in Safe Mode

Safe Mode starts Excel without add-ins or customizations, which are common causes of crashes. This helps determine if the problem is with Excel itself or external add-ins.

Press Windows + R to open the Run dialog box.
Type excel /safe and press Enter.
Excel will open in Safe Mode.
Try using Excel normally to see if it crashes.

If Excel works fine in Safe Mode, the issue is likely caused by add-ins. You can disable add-ins to fix this.

Step 3: Disable Problematic Add-ins

Add-ins extend Excel’s features but can sometimes cause instability. Disabling them one by one helps identify the culprit.

Open Excel normally (not in Safe Mode).
Click File > Options.
Select Add-ins on the left menu.
At the bottom, next to “Manage,” select COM Add-ins and click Go.
Uncheck all add-ins to disable them, then click OK.
Restart Excel and check if it still crashes.
If Excel works fine, enable add-ins one at a time, restarting Excel each time, to find the problematic one.

Step 4: Repair Microsoft Office

Damaged or missing Office files can cause Excel to crash. Repairing Office can fix these issues by replacing corrupted files.

Press Windows + R, type appwiz.cpl, and press Enter to open Programs and Features.
Find Microsoft Office in the list.
Right-click it and select Change.
Choose Quick Repair first and follow the prompts.
If the problem persists, repeat and choose Online Repair (this requires internet and takes longer).
After repair, restart your computer and test Excel again.

Step 5: Update or Reinstall Microsoft Excel

Running the latest version of Excel ensures you have bug fixes and security patches. If updating doesn’t help, reinstalling Excel can fix deeper issues.

Open any Office app and go to File > Account.
Under Product Information, click Update Options > Update Now.
Wait for updates to install, then restart Excel.
If crashes continue, uninstall Office via Settings > Apps > Apps & Features, then reinstall it from the official Microsoft website or your Office account.

Step 6: Check for Conflicting Software

Some third-party programs, such as antivirus or system utilities, can interfere with Excel. Temporarily disabling these can help identify conflicts.

Temporarily disable your antivirus software and see if Excel stops crashing.
If Excel works well, add Excel to the antivirus’s whitelist or consider switching software.
Be cautious when disabling security software and re-enable it after testing.

Step 7: Clear Excel Cache and Temporary Files

Corrupted cache or temporary files can cause Excel instability. Cleaning them can improve performance.

Press Windows + R, type %temp%, and press Enter.
Delete all files in the Temp folder (skip files that can’t be deleted).
Open Excel and test again.
