You could Google 'Excel add-in' and find a variety of tutorials. Read a
couple and experiment.

Basically, an add-in is an Excel workbook, containing sheets. It is not
visible in the Excel window, so a user can't access the sheets, but its code
is available. The best thing to do is build one or more commandbars or menus
that activate the add-in's programs. Any program can still access the data
in the sheets, so you can place information there. One trick is to make a
table containing menu parameters, so the add-in can build the menus it
needs. Editing the table is much easier than editing hard coded menu
parameters. Here's a page that gives instructions and an example for this

This sounds like what I want to do and the right direction for me to take,

You should redesign the package so the data is in a separate workbook,
and
the code is in an add-in. This allows you to (a) use a single version of
the
program with independent sets of data, and (b) update the code without
worrying about any of the data. It is possible to update the code in a
workbook, but it is complicated and requires certain permissions to
access
the VB projects.

touching
the
data. Can this be done by changing the vbaProject.com component within
the
package?
