Excel related problem

Try these steps in order until Excel works again:

1. Start Excel in Safe Mode
   • On Windows 11/10: select Start > All apps > Windows System > Run.
   • Type Excel /safe and select OK.
   • If Excel opens in safe mode, the problem is likely an add-in.
2. Disable COM Add-ins
   • In Excel, select File > Options > Add-ins.
   • At the bottom, choose COM Add-ins and select Go.
   • Clear all check boxes, select OK, then close Excel.
   • Open Excel normally (not in safe mode) and test.
   • If Excel works, re-enable add-ins one by one, restarting Excel each time, to find the problematic add-in.
3. Check Excel add-ins via the registry (advanced)
   • This is advanced and can cause serious problems if done incorrectly. Back up the registry first. For details, see How to back up and restore the registry in Windows.
   • Press Windows key + R, type regedit.exe, select OK.
   • Go to: HKEY_CURRENT_USER\Software\Microsoft\Office\<1x.0>\Excel\Options (for Excel 2016 or newer, <1x.0> is 16.0).
   • In the Name column, look for any REG_SZ values named OPEN (or OPEN1, etc.).
   • Right-click OPEN, select Rename, change it to RenamedOPEN and press Enter.
   • For any other OPEN* values, rename them to start with Renamed (for example, OPEN1 → RenamedOPEN1).
   • Start Excel in normal mode and test.
   • If Excel works, re-enable add-ins one by one by removing Renamed from each name, restarting Excel after each change, to identify the problematic add-in.
4. Investigate startup folders
   • Excel automatically opens workbooks in the XLStart folder and any alternate startup folder.
   • Move files out of these startup folders temporarily and then start Excel to see if one of those files is causing the problem.
5. Perform a selective startup (clean boot)
   • Other programs or services may conflict with Excel.
   • Follow the steps for the version of Windows in Run Selective Startup using System Configuration to perform a selective startup.
   • Test Excel in this clean environment to see if the issue is caused by another application or service.
6. Repair Microsoft 365/Office
   • Repairing Office can fix corrupted components that stop Excel from working.
   • Follow the steps in Repair a Microsoft 365 application to run an Online Repair, which reinstalls Office components.
7. Check environmental factors if Excel still hangs or crashes
   • Save the Excel file locally instead of on a network, SharePoint, or remote location to see if storage location is causing issues.
   • Ensure the PC has enough RAM for large, heavily formatted workbooks. See System requirements for Office 2016.
   • Test with a different default printer (for example, Microsoft XPS Document Writer) and/or a basic video driver, because printer or video drivers can affect Excel performance.

If Excel continues to hang or crash after these steps, contact Microsoft Support for guided troubleshooting.
