How to break an Excel Password

 

There are many ways to protect an Excel spreadsheet from viewing and editing. One of them is to protect cells of selected ranges of the sheet against editing, changing the formatting, etc. There are situations, for example, that we forget our password to the sheet that we would like to unlock. We may also remember a password that, in fact, is incorrect.

The first thing to do is to check if CapsLock is on or off. The most common mistake in typing an incorrect password is CapsLock turned on. Before trying to crack a password in Excel, I suggest checking the password in both uppercase and lowercase.

  • Right Click on the name of the sheet
  • Click Unprotect Sheet…
  • Enter password what you remember
  • Click CapsLock
  • Enter again the same password

In addition, it may be worth trying to check frequently used passwords, such as 123456 or 654321. If these attempts do not help, you can try to crack the password in the sheet by using one of the three methods I have listed below.

Method 1. Using Macro VBA
Method 2. Unzip file and remove relevant code
Method 3. Using Google Sheet

Method 1. Break password using macro (VBA).
File with extension (.xls) version 2003 or before

    • Open a visual basic editor. Alt + F11
    • Right click on Sheet
    • Select Insert > Module
    • Paste code below  in the General Declaration page
Sub BreakPassword()

   Dim i As Integer, j As Integer, k As Integer 
   Dim l As Integer, m As Integer, n As Integer
   Dim i1 As Integer, i2 As Integer, i3 As Integer
   Dim i4 As Integer, i5 As Integer, i6 As Integer

   On Error Resume Next

   For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
   For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
   For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
   For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126

   ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) & _
   Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
   Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)

   If ActiveSheet.ProtectContents = False Then
      Exit Sub
   End If

   Next: Next: Next: Next: Next: Next
   Next: Next: Next: Next: Next: Next

End Sub
  • Run the macro, press F5
