How to a Repair Corrupt Excel file?
You can try the following workarounds to repair a corrupt or damaged Excel file:
- Revert the Excel Sheet to the last saved version: If an Excel sheet gets corrupted while you’re working on it, but before you save the changes, revert to the last saved version.
- Change the Calculation Setting: Set the calculation option in Excel from automatic to manual. As the workbook won’t be recalculated, it may open.
