Parameters

Password

Optional Object. A string that specifies a case-sensitive password for the worksheet or workbook. If this argument is omitted, you can unprotect the worksheet or workbook without using a password. Otherwise, you must specify the password to unprotect the worksheet or workbook. If you forget the password, you cannot unprotect the worksheet or workbook. It's a good idea to keep a list of your passwords and their corresponding document names in a safe place.

Structure

Optional Object. True to protect the structure of the workbook (the relative position of the sheets). The default value is False.

Windows

Optional Object. True to protect the workbook windows. If this argument is omitted, the windows aren’t protected.
