A Table in vba is a ListObject. You can just UniList it.
Notice, however, that you may also want to remove formattting. In that case store the ListObject Range before unlisting it. Ex.:
Code:Sub ConvertTableToRange() Dim rList As Range With Worksheets("Sheet3").ListObjects("Table1") Set rList = .Range .Unlist ' convert the table back to a range End With With rList .Interior.ColorIndex = xlColorIndexNone .Font.ColorIndex = xlColorIndexAutomatic .Borders.LineStyle = xlLineStyleNone End With End Sub
