forgot password of XLSX file.. please help

[anon]

^^ It was a good trick 20 or 30 years ago, but the problem is that these 'classic' letter-to-number substitutions are now well-known, and dictionary-attack methods have been employing them for a long time

It's better than nothing, though.

Even Google is wise to this; search for "c0mput3r" and Google returns results for "computer"

That doesn't count. They're Google. They know everything.

just out of curiosity xlsx (and docx files etc for that matter) are just Zip containers for the xml files etc (rename any file to a zip extension and load in winrar or similar) and you can see all the files, just a matter how and what is therefore passworded with relation to getting the data

Or you can use a faster online recovery service like password-online.com.
They are super fast. Decryptum and others don't offer to decrypt docx or xlsx passwords only the old format.
