Are Excel passwords easy to crack? We have a spreadsheet that we forgot the
password for and was wondering if we could get into it.

How secure are Excel passwords?

Yes and not very, to answer both questions.
Google for "Excel password crack" with the quotes.

Depends which type of password.

Internal worksheet and workbook protection passwords are easily cracked
using Excel VBA or third-party crackers.

Passwords to open a file are more difficult but can be done using
third-party crackers which can be found on the 'net.

Thanks for the post. Does this McGimpsey macro work on a workbook that asks
for a password as soon as you open the workbook? If I open the workbook I
have to either click OK with no password or click cancel and if I run the
macro after that it seems like the macro is not running on the password
protected workbook since it is probably not open.
 
McGimpsey's macro is for internal passwords only...........sheet and
workbook protection.

Will not work for File>Open passwords.

You will need a third-party cracker for that.

Do a 'net search for password crackers.

Thank you very much for the info here... I cannot explain how a password
protected workbook's password would change saving it to a 2007 file format.
Any answers would be greatly appreciated.
 
I know of no reason why the password to open would change by saving as a
2007 file format.

I cannot replicate the behaviour when saving 2003 files as 2007 files.
