Run the Microsoft Office Repair Tool
Use the built-in Windows repair tool to automatically detect and fix corrupted Office installation files causing Excel to crash.
Right-click the Windows Start button and select 'Apps and Features' or 'Installed Apps' from the context menu.
Scroll down the list of installed applications to find your Microsoft Office installation. Click the three dots on the right (or right-click the app) and select 'Modify'.
In the pop-up window, select the 'Quick Repair' option and click the 'Repair' button. Wait for the process to complete and test Excel.
If Quick Repair does not fix the crashing issue, repeat these steps but select 'Online Repair' for a more comprehensive reinstallation of the application files.

Reset Office Configuration via Registry Editor
Renaming the Office registry key forces the application to recreate its default configuration, which can resolve deep-rooted initialization errors.
Test Excel with a New Windows User Profile
If your current Windows user profile is corrupted, creating and logging into a new profile can bypass the conflicts causing the Excel crashing issue.
Switch to WPS Office for a Stable, Crash-Free Experience
If Microsoft Excel continues to encounter errors and disrupt your workflow, consider switching to WPS Office. It provides a lightweight, highly stable environment for all your spreadsheet tasks without the hassle of unexpected crashes.

Frequently Asked Questions
Why does Excel suddenly say it has encountered an error?
This error usually occurs due to corrupted Office installation files, incompatible third-party add-ins, outdated software versions, or conflicting registry settings within the Windows user profile.
What is the difference between Quick Repair and Online Repair?
Quick Repair runs fast and fixes most issues by replacing corrupted files using locally cached data. Online Repair takes longer as it performs a complete reinstallation of Office files by downloading fresh, updated copies directly from Microsoft servers.
Will repairing Microsoft Office delete my Excel files?
No, running the Quick Repair or Online Repair tool only fixes the application's underlying program files. Your personal workbooks, documents, macros, and data will remain completely intact and unaffected.
How do I safely back up the registry before fixing Excel errors?
Open the Registry Editor, navigate to the specific folder or key you plan to modify, right-click it, and select 'Export'. Save the resulting .reg file to a safe location like your desktop so you can double-click it to restore the settings easily if needed.
