excel vba to open a workbook by testing multiple passwords - vba

Question

I have password-protected .xls files in a directory. I would like to open each of these files and save them without the password.
However, the files can be opened by using either of the sample passwords listed below.
pwd1 = "123"
pwd2 = "456"
pwd3 = "789"
'Check if pwd1 opens
Application.Workbooks.Open(Filename:=fn, Password:=pwd1)
'If fail then use pwd2
Application.Workbooks.Open(Filename:=fn, Password:=pwd2)
'and so on..
How should I implement this?

Answer 1

Once the file has been opened once, you only need to Unprotect it. This will save a lot of time, instead of constantly opening/closing workbooks.
Here's how I'd do it:
Public Sub CrackWorkbook()
Dim fn As String
fn = "C:\Temp\test_password_is_456.xlsx"
Dim wb As Workbook
Set wb = Workbooks.Open(fn)
Dim lst As Variant
lst = Array("123", "456", "789")
Dim item As Variant
For Each item In lst
On Error GoTo did_not_work
Call wb.Unprotect(item)
Call wb.Save
Call wb.Close(False)
Exit Sub
did_not_work:
On Error GoTo 0
Next item
End Sub
In other words, create an array of strings and do a For Each on them, and set some error-handling to deal with all the failed attempts.
I know GoTo statements are a bit yucky, but that's the best way to handle errors in VBA (as far as I know).

I tried #lebelinoz answer however the routine gives a 1004 error. I googled this behavior and found this post:
https://stackoverflow.com/questions/21176638/vba-how-to-force-ignore-continue-past-1004-error
The code below works by using On Error Resume Next. I based this on #lebelinoz answer.
Public Sub CrackWorkbook()
Dim fn As String
fn = "C:\Temp\test_password_is_456.xlsx"
Dim wb As Workbook
Dim item As Variant
Dim lst As Variant
lst = Array("123", "456", "789")
For Each item In lst
On Error Resume Next
Workbooks.Open Filename:=fn, Password:=item
If Err.Number <> 0 Then GoTo did_not_work:
Exit For
did_not_work:
Next item
Set wb = Activeworkbook
wb.SaveAs Filename:=fn, Password:=""
wb.Close
End Sub
