Solution 1Recommended

Repair Microsoft Office via Windows Installed Apps

Use the Windows system settings to run a Quick Repair or Online Repair for the entire Microsoft Office suite, bypassing the broken in-app repair prompt.

Since the internal repair prompt within Excel is crashing before it can execute, you must trigger the repair tool directly from the Windows operating system settings.

1
Open Windows Settings

Press the Windows key on your keyboard, type 'Settings', and press Enter. Navigate to 'Apps' and select 'Apps & features' or 'Installed apps' depending on your Windows version.

2
Locate Microsoft 365 or Office

Scroll through your list of installed applications or use the search bar to find 'Microsoft 365' or your specific version of Microsoft Office.

3
Select the Modify Option

Click the three vertical dots (or click directly on the app name) next to the Microsoft Office entry and choose 'Modify'. If Windows prompts you for administrative permission, click 'Yes'.

4
Run a Quick Repair

In the Office repair dialog box, select 'Quick Repair' and click the 'Repair' button. This process runs locally and fixes most corrupted files quickly without an internet connection.

5
Run an Online Repair (If Needed)

If Excel still crashes after the Quick Repair finishes, repeat these steps but select 'Online Repair' instead. This performs a comprehensive fix by reinstalling corrupted components.

Restart Required: Always remember to restart your computer completely after the repair process finishes before attempting to open Excel again.

Frequently Asked Questions

What is the difference between Quick Repair and Online Repair for Microsoft Office?

Quick Repair runs faster and fixes most corrupted files locally without needing an internet connection. Online Repair uninstalls and completely downloads fresh Office components, which takes longer and requires a stable internet connection but fixes much deeper software issues.

Why does Excel show a repair prompt and immediately close?

This usually happens when core application files, registry keys, or essential dependencies are heavily corrupted. The app recognizes the corruption and triggers the prompt, but the corruption is too severe to sustain the application instance, causing it to crash before the repair initiates.

Will repairing Microsoft Office delete my personal Excel files?

No, running either a Quick Repair or an Online Repair on Microsoft Office only affects the application's installation files and software registry settings. Your personal workbooks, spreadsheets, and saved data remain entirely untouched and safe on your hard drive.

What should I do if Online Repair fails to fix the crashing issue?

If both Quick and Online repairs fail, you should completely uninstall Microsoft Office using the official Microsoft Support and Recovery Assistant (SaRA) tool to remove leftover corrupted files. Afterward, log into your Microsoft account online and download a fresh installer for Office.
