Fixing an error in Excel can be super straightforward. Usually, you just need to follow a few simple steps to get your workbook back up and running. By the end of this guide, you’ll know how to identify and resolve common Excel issues, ensuring your spreadsheets work perfectly again.

How to Repair Excel

Let’s walk through the process step-by-step to repair your Excel files. This will help you address common issues like corrupted files, application crashes, or formula errors.

Step 1: Open Excel in Safe Mode

To start, open Excel in Safe Mode by holding down the ‘Ctrl’ key while launching the program.

Safe Mode helps you troubleshoot problems by disabling add-ins and extensions that might be causing the issue.

Step 2: Check for Updates

Next, go to ‘File’ > ‘Account’ > ‘Update Options’ and select ‘Update Now’ to ensure Excel is up-to-date.

Keeping Excel updated can prevent many issues as updates often include bug fixes and performance improvements.

Go to ‘Control Panel’ > ‘Programs and Features,’ find Microsoft Office, and select ‘Change.’ Choose ‘Quick Repair’ or ‘Online Repair.’

Quick Repair fixes common issues quickly, while Online Repair takes longer but can resolve more complex problems.

Add-ins can sometimes conflict with Excel, causing it to crash or behave unexpectedly. Disabling them can help identify the culprit.

This step allows you to retrieve any workbooks that may have been lost due to a crash or unexpected shutdown.
