Excel Password Recovery Master by Rixler Software
Windows, shareware, free trial, $29.95 Personal / $59.85 Business License (download, purchase)

This program will crack password-protected documents created in Excel 97/2000/XP/2003/2007/2010 (*.xls, *.xlt, *.xla, *.xlsx files). The program allows you to crack "open" (except for *.xlsx files), "write", workbook, shared workbook, and worksheet passwords.

According to the vendor, the program sends a tiny "technical" portion of the Excel document file to the vendor's server, whereas "all sensitive data remains on the user's computer". The server typically recovers the encryption key (that Excel "derives" from the password) in seconds, thereby enabling the program to decrypt the document. Thus, no matter how long and strong the password is, the program will crack the encryption and provide you with the decrypted and unprotected Excel document.

Many other programs will instead actually search for the password (so the attack success and duration will depend on password strength) or attempt to crack the encryption key on your own computer (which may take days).
