DOCX to HTML Converter
This skill provides a straightforward method to convert Microsoft Word (.docx) documents into clean, semantic HTML, making them suitable for various web-based and AI-driven applications.
Compatibility
- Python 3 (for the conversion wrapper)
- Node.js with
mammothinstalled (core conversion engine)
To install Node.js dependencies, run once from the scripts/ directory:
npm install
Use Cases
- Browser-Based Viewing: Convert DOCX documents for display in web browsers without requiring Microsoft Word.
- AI-Ready Content: Prepare DOCX content for LLMs for tasks like summarization, Q&A, and semantic search.
- Web Integration: Integrate Word document content into web applications, CMS, or online editors.
- Data Extraction: Extract structured data (tables, lists, headings) from DOCX files for automated reporting and analysis.
- Search and Indexing: Enable full-text and vector search by converting DOCX content into easily indexable HTML.
Workflow
-
Locate DOCX File: Identify the path to the
.docxfile to convert. -
Run Conversion Script: Execute the Python wrapper from the skill's
scripts/directory:python3 <skill-dir>/scripts/convert.py <input_path.docx> <output_path.html>Replace
<skill-dir>with the actual path where this skill is installed. -
Verify Output: Open the generated
.htmlfile in a browser and check:- Headings (
<h1>,<h2>, etc.) appear at the correct hierarchy levels - Tables render with the expected rows and columns
- Lists appear as bullet or numbered items (not plain text)
- Bold, italic, and inline formatting are preserved
- Images are visible (embedded as base64 by default)
- Headings (
-
Process HTML: Use the resulting HTML for further tasks like summarization, indexing, or display.

Technical Details
The conversion leverages mammoth.js, which prioritizes semantic meaning over visual replication:
- Semantic Conversion: Document structure maps to proper HTML — headings become
<h1>/<h2>, lists become<ul>/<ol>, etc. - Basic Styling: Bold, italics, and common paragraph styles are preserved.
- Image Embedding: Images are extracted and embedded as base64 data URIs in the HTML output.
Troubleshooting
| Problem | Likely Cause | Fix |
|---|---|---|
node: command not found | Node.js not installed | Install Node.js (v16+) |
Cannot find module 'mammoth' | npm deps missing | Run npm install in scripts/ |
| Empty or garbled output | Corrupted or password-protected DOCX | Try re-saving the file from Microsoft Word |
| Missing images | Large embedded images | Check mammoth.js image size limits in docx-converter.js |
Limitations
- Advanced or highly specific styling from the original DOCX may not be perfectly replicated in the HTML output.
- Features like tracked changes, comments, or complex layout elements may be simplified or omitted.
