Incorporating Row&Column deletes into code

I have a code I have been using to export a bunch of worksheets to csv files.
I am hoping to incorporate a couple lines to delete a few rows and columns in the csv, but not in the original export file.

Can you guys give me some lines to hopefully put in.

Sub testexport()
Dim i As Integer
Dim sName As String
     
 For i = 3 To 69
     
   Sheets(i).Activate
     
   sName = ActiveSheet.Name
   
    Range("A1:W645").Copy
    Workbooks.Add
    ActiveSheet.Paste
    ActiveWorkbook.SaveAs Filename:="S:\Com\Monthly\Test\" & sName & ".csv", FileFormat:=xlCSV, CreateBackup:=False
    Application.DisplayAlerts = False
    ActiveWorkbook.Close
    Application.DisplayAlerts = True
    
Next
     
End Sub
