Excel WorkSheet Password

Filed under: Microsoft Excel — Tags: , , , , — deshnilesh @ 5:12 pm

I again forgot my password for a excel worksheet and then begin mission to crack it :). Fortunately I cam across this code which will give you a alternate password. There is more detail discussion about how it works on the site, I am copying the code here for my reference so in future if I need it again I won’t have to search again.
