Password protection is the easiest way to keep the contents of any document private and this method is often used in many documents with highly sensitive information. As you can expect, password protection can be a very valuable asset, particularly for businesses that handle or deal with sensitive information, not meant for the public. They serve to keep the information in the document only available to the few ones who need the information.
But on the flipside, a password-protected Excel worksheet can be very problematic to handle especially when you don't know the password or if you somehow lose a complex password and can't remember it. It can be even worse if only sections of the document have been protected, meaning that you can't edit or format any part of the Excel sheet.

Dictionary attack can be used for various file types. It works by allowing you to try all password combinations although you can also provide one of your own from the settings menu.
Combination Attack identifies the password by combining all the letters, numbers and symbols you provide even if they are sensitive information.
Mask Attack is the attack mode to choose when you have a clue as to the possible password. It works by considering all aspects of a password including the characters, suffixes, prefixes and even the length of the password. You provide Passer for Excel with any information you may have about the password and the program works out what the password could be.
Brute force attack is the best solution if you don't know the password and have no clues as to what it may be. Because there is very little information to recover the password, a Brute force Attack may take longer than the others.
