Remove known password from directory of Excel files with VBA - excel

Question

I have found this VBA code and it works to remove the known password on one Excel workbook just fine.
Sub testPasswordRemoval()
Dim wb As Workbook
Set wb = Workbooks.Open(Filename:="C:\Temp\Book2.xlsm", Password:="pw")
wb.Password = ""
wb.SaveAs "C:\Temp\NewBook.xlsm"
End Sub
But, I have tried various tutorials and videos (many folks offering this) but none of them work to loop through a folder of .xlsx files (all with the same known password) and remove that same password.
I am not a VBA person, but have spent about 16 hours over the past three days trying to crack the code on this one. I have found several examples of looping over files in a directory, but none that enabled me to put the above code into them and loop and remove passwords.

Try this code, read the comments, and adjust it to fit your needs
Code:
Public Sub RemovePassLoopThroughFiles()
Dim targetWorkbook As Workbook
Dim filePath As String
Dim folderPath As String
Dim folderWildcard As String
Dim currentFileName As String
Dim currentFileExtension As String
Dim newFileName As String
Dim newfileNameSuffix As String
Dim currentPassword As String
Dim newPassword As String
' Adjust next lines to fit your needs
folderPath = "C:\Temp\" ' With slash at the end
folderWildcard = "*.xls*" ' You can change the suffix to open specific files
newfileNameSuffix = "_NoPassword"
currentPassword = "pw"
newPassword = ""
' Get the file path concat folder and wildcards
filePath = Dir(folderPath & folderWildcard)
Do While Len(filePath) > 0
' Open the workbook and set reference
Set targetWorkbook = Workbooks.Open(Filename:=filePath, Password:=currentPassword)
' Get current file extension
currentFileExtension = Right(filePath, Len(filePath) - InStrRev(filePath, "."))
' Get filename no extension
currentFileName = Left(filePath, InStrRev(filePath, ".") - 1)
' Build new fileName
newFileName = currentFileName & newfileNameSuffix & "." & currentFileExtension
' Set new password
targetWorkbook.Password = newPassword
' Save new file
targetWorkbook.SaveAs folderPath & newFileName
'Debug.Print filePath
filePath = Dir
targetWorkbook.Close True
Set targetWorkbook = Nothing
Loop
End Sub
Let me know if it works.
