VBA to open .csv file with notepad save as .txt

I need to create a macro that will open a .csv file, but open it in notepad (this preserves the formatting that I require) then save this open notepad as a .txt file.

My current code will open the .csv file in notepad as required. But I cannot save is as a .txt file with the same FileName.

Any suggestions?

    Dim FileName As String
    Dim FilePath As String
    
    FileName = "file1"
    FilePath = "C:\folder_structure\"
    
    'This opens the .csv file in notepad and works
    Shell "notepad.exe " & FilePath & FileName & ".csv", vbNormalFocus
    
    '***** The comments below contain the approaches I have tried but none work *****
    
    'ActiveWorkbook.SaveAs FileName:=FilePath & FileName & ".txt.", FileFormat:=xlCSVWindows
    'Application.SaveAs fileName:=FilePath & fileName & ".txt.", FileFormat:=xlCSVWindows
    'ActiveDocument.SaveAs fileName:=FilePath & fileName & ".txt.", FileFormat:=xlCSVWindows

    
    'in essense I want this
    open notepad .SaveAs FilePath & FileName & ".txt"

>Solution :

You could try FileCopy:

FileCopy FilePath & FileName & ".csv", FilePath & FileName & ".txt"
