WordPress Plugin export front end

I'm looking for a WordPress plugin that allows to export in a generic format(csv, xls, etc.) the posts belonging to a particular category . A fundamental requirement is the ability to make the export directly from the frontend. I tried dozens of plugins but no one seems to do what I need.

Thanks and sorry for my bad english.

P.S. My interest is mainly in exporting post titles and dates. The actual content is not essential
