how to save .xlsm fie as .xlsx

Hi,

I am trying to save a workbook after macro has run as .xlsx so that same file can be sent to users without macro, but if I use below code it throws error
[code]
Dim ThisFile As String
ThisFile = "Regulatory Reporting " & Format(Range("G21").Value, "dd.MMM") & ".xlsx"
MsgBox ThisFile
ActiveWorkbook.SaveAs Filename:=ThisFile
[\code]

and if changed as below (.xlsm) then it works without any trouble

[code]
Dim ThisFile As String
ThisFile = "Regulatory Reporting " & Format(Range("G21").Value, "dd.MMM") & ".xlsm"
MsgBox ThisFile
ActiveWorkbook.SaveAs Filename:=ThisFile
[\code]

Any Idea how can I change the file type ?

I think you need to specify the fileformat (51 for macro-free workbook)

Sub Test()
Application.DisplayAlerts = False
Dim ThisFile As String
ThisFile = ActiveWorkbook.Path & "\Regulatory Reporting " & Format(Range("G21").Value, "dd.MMM") & ".xlsx"

ActiveWorkbook.SaveAs Filename:=ThisFile, FileFormat:=51

Application.DisplayAlerts = True
End Sub
