How to Fix a Corrupt XLS File

1. Locate the file that requires repair. For best results, copy the corrupt file to a stable hard drive, if it is located on removable media or on a networked device.
2. Click 'File->Open...,' (Excel 2003), or the 'Office Button,' then 'Open.' (Excel 2007).
3. In the 'Open' window, select the corrupt file.
4. Click the drop-down arrow next to the 'Open' button, and select 'Open and Repair' from the menu. Excel will open the file in 'File Recovery' mode and attempt to repair the corruption.
