Excel issues

Use a full Office repair from Windows, not only the small Repair Now button in the Excel pop-up.

1. Close Excel.
2. Right-click Start.
3. In Windows 11, select Installed apps. In Windows 10, select Apps and Features.
4. Find Microsoft Office or Microsoft 365 in the app list.
5. Select it, then choose Modify.
   • If needed, select the three dots first.
6. In How would you like to repair your Office Programs, select Online Repair.
7. Select Repair and complete the on-screen steps.

Notes:

• This repairs the entire Office suite, not only Excel.
• Online Repair is more complete than Quick Repair.
• A restart may be needed after the repair.

If Excel still does not open after the repair, the next likely cause is an add-in conflict. Test by disabling add-ins one at a time:

1. Open Excel.
2. Go to File > Options > Add-Ins.
3. At the bottom, in Manage, select COM Add-Ins > Go.
4. Clear one add-in, then select OK.
5. Restart Excel and test again.
6. If the issue continues, repeat with the next add-in.
7. If needed, repeat the same process with Excel Add-Ins.

If Excel opens after one add-in is disabled, that add-in is the cause.

If the problem started when opening a specific workbook, try repairing that file:

1. In Excel, select File > Open > Browse.
2. Select the workbook.
3. Select the arrow next to Open.
4. Select Open and Repair.
