Unprotecting All Sheets in Excel Workbook

I had an Excel Workbook that had password protected sheets but I didn't know the password. Having a look online, I was able to find a password breaking / unprotecting VBA script which worked fine. The only issue I had now was that there was a total of 40 sheets that needed unprotecting. Running this script individually on each sheet would have been possible but seemed like a daunting task. Therefore, with my limited VBA skills I modified the script to cycle through all the sheets in the workbook and unprotects any sheets that were protected. It’s not the prettiest but it did the job beautifully and will hopefully prove useful to someone else.

Please note that this script will only work against the older .xls file type and not the newer .xlsx. One way to get around this is saving the workbook as the older type, run the script and then save the now unprotected workbook as the newer type. Though bear in mind that this may cause issues with formatting etc. due to the conversion process.

This is the modified VBA script that I came up with:

Sub Main()
    Dim WS_Count As Integer
    Dim WS_I As Integer
    WS_Count = ActiveWorkbook.Worksheets.Count

    'Loop through all the sheets
    MsgBox "Starting..."
    For WS_I = 1 To WS_Count
        Call PasswordBreaker(WS_I)
    Next WS_I
    MsgBox "Done!"
End Sub

Sub PasswordBreaker(WS_I)
    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
        'If Sheet is not protected break out to try the next one
        Exit Sub
    End If
    Next: Next: Next: Next: Next: Next
    Next: Next: Next: Next: Next: Next
End Sub
