Tell me abt ur version of MSExcel.
R u forgot ur password ??

try below link[^]

i Tried in 2003 XLS file, using Excel 2007

1. Backup the xls file
2. Using a HEX editor, locate the DPB=... part
3. Change the DPB=... string to DPx=...
4. Open the xls file in Excel
5. Open the VBA editor (ALT+F11)
6. the magic: Excel discovers an invalid key (DPx) and asks whether you want to continue loading the project (basically ignoring the protection)
7. You will be able to overwrite the password, so change it.
8. Save the xls file
9. Close and reopen the document and work.
