Functionality can be added with paid modules.

• Html Module to insert formatted text in a docx document with the syntax {~html};
• XLSX Module to be able to do templating on Excel files (xlsx extension), also with loops and conditions;

Similar libraries

Docxtemplater is my main job, and has been maitained for over 8 years already. Expect to get great support if you buy any modules, and also good support on the open-source version.

There are a few alternative libraries that work with Word/Powerpoint documents, here’s a list of those I know a bit about:

• docx4j : JAVA, this is probably the biggest docx library out there. There is no built in templating engine, but you can generate your docx yourself programmatically;
• docx : Javascript in the browser, you can create your docx from scratch, but not with template syntax, you need to "code your document" in Javascript;
• redocx : Create Docx document from scratch, using JSX syntax, last commit on December 2018;
• officegen : works only server side for the moment, last commit on March 2021;
