Hi Jannes,
Check the both articles. I hope it will help you.
Hi Jannes,
I have created a heavily used solution to update Word Templates with Mendix content. The use case is particularly already having a Word template and enriching it, not necessarily creating it from scratch. So, my solution could be used, but not the best fit.
Demo app: https://marketplace.mendix.com/link/component/111539
Module itself: https://marketplace.mendix.com/link/component/244302
I actually think for your use case document templates are still the best way to go. Perhaps this is worth a support ticket to Mendix to ask them about your use case?
