Hi Vikki, We have been using dynamic templates for a few years now. There is no way of merging variable data via an Excel or csv file. Each page has to be setup individually - you can't even copy and paste pieces from one page to the next. However, InDesign does have the capability to do data merge - they would be better off using that. We have attempted to use dynamic templates for flyers, postcards, invitations, brochures, etc., and none have been successful. The templates are difficult and time consuming to setup, require extensive testing and training, and if they contain too many editable pieces, most end users get overwhelmed and just want a designer to do it for them. Our only successes have been email banner headers in which a single image is switched out and social media posts in which only a small amount of text is changed. Hope that helps. -Tina Tina Craig Houghton Mifflin Harcourt Publishing Company
