Hello everybody! When I start using docxtemplater I have no online sandbox to try it out. Later I made something like that and with some improvements it helps me with template work. I have two stages with template work: checking correctness and compatibility of data and template (1) and appearance work. On the first stage I use Mustache text templater instead docxtemplater. They have compatible core so I can interactively check correctness and compatibility and generate docxtemplater template for second stage. See example in YouTube video.

This page use docxtemplater 3.0.9
