Excel Error

That built-in Repair Now prompt may not complete the full Office repair. The supported next step is to run an Online Repair for Office manually.

1. Close Excel and all other Office apps.
2. In Windows, right-click Start and open:
   • Installed apps on Windows 11, or
   • Apps and Features on Windows 10.
3. Find Microsoft 365 or Microsoft Office in the list.
4. Select it, then choose Modify.
5. In the repair window, select Online Repair > Repair.
   • Online Repair is the more complete option.
   • Quick Repair is faster, but it only detects and replaces corrupted files.
6. Follow the on-screen steps and let the repair finish.
7. Restart the PC.
8. Open Excel again and test the file.

If Excel still opens to a blank screen after the repair, the recommended action remains an Online Repair.

If Excel opens but a specific workbook fails, try recovering that file with Open and Repair:

1. Open Excel.
2. Select File > Open > Browse.
3. Select the workbook.
4. Select the arrow next to Open.
5. Choose Open and Repair.

If Excel hangs or freezes during startup, test it in safe mode by running excel /safe. If it opens there, an add-in may be causing the problem.

Also make sure Office is fully updated. A known Excel file-access hang issue was fixed in version 16.34 and later.
