as a user I would like to export the template data in a format that can be imported to other applications (JSON strongly preferred).
currently, users can only export data to pdf, or html, using confluence tools. Having the ability to export in a format that can be imported to other apps will allow the plugin to be used as content generation for other tools.
The export should allow selecting multiple pages. May be allow list of pages to be in the body, and then possible to enumerate pages using existing page selection macro like content by label, children-list, etc to be used for selecting the pages
