Add the ability to export content as a CSV or Excel file

I work at an agency and some of our clients like to be hands-on with their content. I intend to create a content template with all fields set to Plain Text, so it almost functions as a form. We’ll have our clients fill out the “form” to provide their content and use Slickplan to track status and such, then I’d like to export the content for all pages to a CSV file so we can upload to our custom-built data warehouse. I’m aware this is likely an unusual use case, but we are likely to have a lot of these websites in the future.
