Envelope

Lightweight office document-to-HTML parser written in pure JavaScript. Compatible with both Microsoft and OpenDocument formats. Designed to run in a browser context out of the box.

Currently supports:

• DOCX
• PPTX (partially)
• XLSX (partially)
• ODT
• ODP (partially)
• ODS

Not planned:

• DOC
• PPT
• XLS

Known issues:

• Page/sheet/slide sizes aren't parsed. The output scales based on the browser's viewport.
• PPTX files currently only implement the bare minimum, and are thus missing support for most elements and most formatting details.
• XLSX files are missing (all?) formatting.
• ODP files inherit elements from ODT/ODS, but anything specific to presentations is likely missing.
• ODS files may be missing formatting in certain areas. This has to do with some kind of "default" cell styling that isn't being applied for now.

Usage

import parseDOCX from "./parseDOCX.js";
// OR: import { parseODT } from "../parseODF.js";

const getHTML = async (bytes) => {
  return await parseDOCX(bytes);
};

const bytes = u8array; // Uint8Array containing DOCX file data
getHTML(bytes); // Returns Promise to HTML string

See test/test.js for a practical example.

Contributing

When submitting issues or pull requests, keep in mind that this project exists primarily as a sister project under https://convert.to.it/, and secondarily as a simple drop-in solution for document parsing on the web. That is to say, keep things lightweight and don't break compatibility with p2r3/convert.
