Behind the Errors: What Breaks an Excel Spreadsheet?
Often, corruption happens due to something external to the workbook itself. This could be a crash that happened in the middle of saving it, a bad sector on the hard drive where it is located, a broken transfer, or a virus scan that finds and quarantines a segment of the file. You can use the "Open and Repair" option of Excel, but it usually gives up if the corruption is too severe, leaving the file in an unreadable format or just recovering an empty copy of the original file.
SysInfo Excel Recovery doesn't work like this. It scans the file at the structural level, taking all of the useful data stored in the corrupted file without modifying it during the repair.
