Bundle Multiple Excel Files

I’m looking to bundle multiple Excel files into a single product. Is there any way to bundle these into one EXE and allow the user to select which one they would like to open?

Yes, you can bundle multiple Excel files into a single EXE file using a tool like XLS Padlock. However, with the current approach of XLS Padlock, you must define a main workbook and other workbook files would be considered as companion files.
End users will not be able to select the workbook to open. It’s the main one that will be opened: but on this “main” workbook, I’d create a menu and place buttons with macros that would then open the companion workbooks.
