title: Excel CodeModule doesn't save added code
body: <p>I have hundreds of excel files that need to be extended with code and new sheets. When I add the code first, it saves correctly. Unfortunately the code contains references to the sheets that needs to be added. So I have to add the sheet before... But then the problem occurs, that the added code is not saved within the workbook. Even if added the sheet manually... I'm not able to add code in any way.</p>
