Excel Password Hash Extraction
#1
Question 
I have an xlsx file that is not encrypted but still requires a password to enable editing.

Using office2hashcat gives me an error:
Quote:holiday.xlsx : zip container found, file is unencrypted?, invalid OLE file!

Is there any other way I can extract the hash?

Do you know how old the file is? It's possible this file is simply using the older VBA script password prompt, which is easily removable and doesn't require cracking.

Yes, the write protection password can simply be stripped out of the document.

Renam your .xlsx into .zip, open it, and edit the settings file.
