How to I automate the conversion of .xls workbooks to .xlsm?
You can try this code:
Sub TrandformAllXLSFilesToXLSM()
Dim myPath As String
myPath = "C:\Excel\"
WorkFile = Dir(myPath & "*.xls")
Do While WorkFile <> ""
If Right(WorkFile, 4) <> "xlsm" Then
Workbooks.Open FileName:=myPath & WorkFile
ActiveWorkbook.SaveAs FileName:= _
myPath & WorkFile & "m", FileFormat:= _
xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
ActiveWorkbook.Close
End If
WorkFile = Dir()
Loop
End Sub
