What is Excel File Corruption and Why It Matters

Excel file corruption occurs when the file structure is damaged, making it unreadable by Excel. This can happen due to sudden system crashes, virus attacks, improper shutdowns, or storage issues. For businesses, corrupted files can lead to data loss, missed deadlines, and financial repercussions. Understanding how to fix and prevent these issues is essential for maintaining data integrity.

2. Recover Data from a Backup: Restore the file from a recent backup if available.
3. Try Opening in Safe Mode: Launch Excel in Safe Mode to bypass add-ins that might cause corruption.
4. Import Data into a New Workbook: Use Excel's "Get Data" feature to import sheets from the corrupted file.
5. Use Third-Party Recovery Tools: Tools like Stellar Repair for Excel can recover severely damaged files.
