I use passware myself, although it has a different way of doing things it seems. I ran a quick test to see if it would grab the passwords for a protected worksheet, so I protected worksheet 2 with a password of "test" and then ran the passware program on it. The program came back with worksheet 2 protected by password "BWQMPQHPZCXUXAU", so I plugged this into the worksheet and sure enough it unprotected the sheet. Just FYI
