If the password was in your mind at one time, it's probably still there.
If you can remember what you were doing when you first use it, it might 
come back, or you might recall it in a hypnotic trance.

a) How much are you willing to pay for password recovery?
b) How long are you willing to wait for said password to be recovered?

1.  Sadly, your other responders are right: The task is close to 
impossible -- brute-force trial and error is the only way.


2.  For the future, my suggestion is to either NEVER use passworded 
files, or use software like Keypass to create and store strong passwords 
that you won't forget.  Just Google "Keypass" or "Password Managers."

In addition to what Dennis says (below), it may be possible to decrypt your 
file using brute force; that process may tie your computer up for days/weeks 
while it tries every combination. While this is possible, it is hardly 
practicable.

I remind you that passwords are case sensitive, just in case you have forgotten 
that. Check your caps lock key and try again.

RE: spreadsheet password

[Dennis E. Hamilton]

The Save with Password functions of Apache OpenOffice use serious encryption 
techniques that require the original password to be known.

There is no means to recover the password from the files.  There is no means to 
recover the file without discovering the password.

The weakest point in this procedure is the password itself.  There are programs 
that attempt to discover weak passwords by rapid, automated trials of 
commonly-used passwords, short passwords, ones with inadequate variety 
including well-known patterns.

You might find a program that offers to decrypt OpenOffice files (assuming you 
are using .ods for your spreadsheets) although there is usually no promise to 
succeed and the free trial will perhaps not try long enough.  If you pay for 
one of those, there still may not be any solution in a reasonable amount of 
time spent running the program.  The risk is yours.

It is the purpose of Save with Password to be this difficult and keep whatever 
your data is that private.

There is a slight risk that a file is damaged in such a way that the correct 
password is also unsuccessful.  Since you mention several spreadsheets, that is 
likely not the case.
