I am looking for some guidance, pointers and examples to do the following in
Excel 2003 (or later).
Given a workbook with 3 worksheets with each worksheet containing unique
tables, I would like to add toolbar menu options such that the user is able
to:
1. Export every table to one single XML file
2. Export a single table to an XML file
3. Import XML files into the workbook overriding all exiting data
4. Import XML files into the workbook appending the existing data
This file will be a template file where users can save and share data
through the XML files.
Any help is appreciated. Ive found some XML information but not to the
level I need to achieve.

TIA
- Pat
