Repairing a Corrupted File:
Excel offers several repair methods:
- Automatic Repair: Excel attempts to repair the file upon opening, often presenting a message about "repairing a problem."
- Open and Repair: This option is available in the "Open" dialog box and allows you to choose between attempting to repair the file or extract data.
- Third-Party Tools: Specialist software can be used to repair heavily corrupted files, offering advanced recovery options.
Preventing Corruption:
