Encountering the "Excel couldn't start last time" error can be a frustrating experience, especially when you're eager to dive into your spreadsheets. This error often indicates that Excel is struggling to open due to some underlying issues, ranging from corrupted files to problematic add-ins. But don't worry! With the right steps, you can effectively troubleshoot and resolve this issue. In this guide, we’ll explore seven helpful tips to get your Excel back on track and ready for action. 💪

1. Open Excel in Safe Mode

When facing issues with Excel, one of the simplest and most effective ways to diagnose the problem is to start it in Safe Mode. Safe Mode launches Excel without any add-ins, which might be causing the error.

2. Type excel /safe and hit Enter.
3. If Excel opens without any errors, then it's likely an add-in causing the problem.

3. Uncheck the problematic add-ins and restart Excel.

2. Temporarily disable any antivirus or firewall software.
