In simple English
This tool fills out Word documents, PowerPoint presentations, and Excel spreadsheets using your data. You design the layout using standard office software with special tags inside curly braces. Your code then feeds numbers or text into those tags to produce finished files. Many important features require paid add-ons, and the main licence restricts commercial use. It helps you automate invoices, reports, or contracts without writing complex layout code from scratch.
What it is
JavaScript (a programming language that runs in web browsers and on servers) library that reads office document files and replaces designated placeholders with dynamic data. It processes loops and conditions so you can build tables and repeat sections automatically.
What it is good for
Solo builders who need to generate custom PDF alternatives, invoices, or client reports directly from a server or web application.
- Works with familiar office editors so non-programmers can update layouts.
- Handles loops and conditions directly inside tables and paragraphs.
- Runs in both Node.js (a system that lets you run JavaScript outside a web browser) and web browsers.
- Custom licence requires careful reading for commercial projects.
- Many advanced features and formats need paid add-on modules.
- Debugging broken template XML (Extensible Markup Language, a way to structure data in plain text) tags can be frustrating.
