I created a document on 2002, and I today I was checking old Floppy Disk and I found that document. I realize that with my mom's job as a teacher, I can modify the document for her, but I protect it and it's been so long since I used it that I forgot the password.

Does anyone know a way to crack the password? I used "Excel 2003" to create this document.

Note: I hope this is the right forum to ask this.
