- Product

- Device & OS
- Windows 11
- Scenario
- Opening existing spreadsheets or creating new workbooks for data entry.
- Observed behavior

Ensure you have administrative access to your Windows 11 computer and have your Microsoft Office account login details ready, as you may need to reinstall the software.
Reinstall Office Over the Existing Installation
If standard repair tools fail, installing Office directly over your current corrupted installation can replace missing or damaged files without removing your personal settings.
In cases of severe file corruption where the Online Repair tool fails, overwriting the existing installation forces Windows to replace core program files without wiping user data.
Go to the official Microsoft website and log in with the account associated with your Office subscription to download the installation file (setup.exe).
Locate the downloaded setup file on your Windows 11 computer and double-click to run it. Do not uninstall your current Microsoft Office suite beforehand.
Follow the on-screen prompts to complete the installation process over your existing software.
Once the setup finishes, restart your Windows 11 computer. Open Microsoft Excel and try loading an XLSX file to verify the issue is resolved.

Start Excel in Safe Mode and Disable Add-ins
Safe mode bypasses third-party add-ins, helping you identify if a recently installed extension or macro is causing Excel to crash.
Run the Microsoft Office Online Repair Tool
Windows includes a built-in utility specifically designed to detect and repair broken Office application components over the internet.
Try WPS Office to Open Your XLSX Files Without Crashing
If Microsoft Excel continues to crash on your Windows 11 PC, consider switching to WPS Office. It is a highly stable, lightweight office suite that handles spreadsheets effortlessly and prevents productivity loss.
- 1. Download and Install WPS Office: Click the download button to get the free WPS Office installer, then run it on your Windows 11 PC.
- 2. Open WPS Spreadsheet: Launch the WPS Office application and click on 'Spreadsheet' from the main dashboard.
