I don’t see an opportunity to do that in the dialogs in Excel 2011 - it may be a later option.
This means that you either put the macro into each new workbook or you import into a master workbook and save it under another name.
That sounds odd and it obviously adds another layer to the task.
My package is essentially a single-step solution in which the user doesn’t have to do any Excel fiddling at all. But thank you for the input - the community now has two choices for handling the problem.
I assume that my package ran satisfactorily in Excel 2016?
