.docx generator working with templates and data (like Mustache)


docxtemplater is a library to generate docx/pptx documents from a docx/pptx template. It can replace {placeholders} with data and also supports loops and conditions. The templates can be edited by non-programmers, eg for example your clients.

Note: The CLI will soon be moved to another repository : keep posted on

Demo Site

Installation: npm install docxtemplater

var fs = require('fs');
var Docxtemplater = require('docxtemplater');
//Load the docx file as a binary 
var content = fs
    .readFileSync(__dirname + "/input.docx", "binary");
var doc = new Docxtemplater(content);
//set the templateVariables 
    "description":"New Website"
//apply them (replace all occurences of {first_name} by Hipp, ...) 
var buf = doc.getZip()

You can download input.docx and put it in the same folder than your script.

You can directly download built versions from github :

They are a few similar libraries that work with docx, here’s a list of those I know a bit about:

  • docx4j :JAVA, this is probably the biggest docx library out there. They is no built in templating engine, but you can generate your docx yourself programmatically
  • docx.js: Javascript in the browser, you can create (not modify) your docx from scratch, but only do very simple things such as adding non formatted text
  • xlsx-templater : its working quite well, does the same as here but for xlsx


Functionality can be added with modules. They is yet no doc for the modules because it is not completely mature yet, but you can open an issue if you have any question about it.

Here is the list of existing modules:
