.xltm into excel file which still contains the macro

I have an excel file which have macros , and in its vb code the file is saved as .xltm file but i want to change it to some other format which would containd the macros .

my code behind the save and close button is :

Sub Save_As()
    If MsgBox("Are you sure you want to Exit now?", vbYesNo) = vbNo Then Exit Sub
    ActiveSheet.Unprotect Password:="C0g!
    For Each ws In ThisWorkbook.Worksheets
        With ws.UsedRange
            .Copy
        .Cells(1, 1).PasteSpecial Paste:=xlPasteValues
    End With
Next ws

Application.CutCopyMode = False

    ActiveSheet.Shapes("UpdateTemplate").Delete
    ActiveSheet.Shapes("SaveClose").Delete
    Range("F18").Select
    ActiveWorkbook.SaveAs Filename:="O:\QA Files\Pending Review\" & Range("D12") & "_" & "BagGla" & "_" & Range("D6") & "_" & Format(Now(), "YYYYMMDDhhmmss") & ".xltm", FileFormat:=53

    If Workbooks.Count = 1 Then
        Application.Quit
    Else
        ActiveWorkbook.Close savechanges:=False
    End If
           
End Sub

PLease help me finding a way in which i can save this .xltm file as another file(any format ) which should contains all the macros and data which this file would have.Thanks
