When & Why to Use This Skill

This Claude skill enables comprehensive DOCX document management, allowing for the professional creation, editing, and analysis of Microsoft Word files. It specializes in maintaining document integrity through advanced features like tracked changes (redlining), comment management, and formatting preservation. By integrating tools such as Pandoc for extraction and docx-js for generation, it provides a robust workflow for handling complex business and legal documents programmatically.

Use Cases

  • Legal Contract Review: Automate the 'redlining' process by programmatically adding tracked changes and comments to legal agreements while preserving original formatting.
  • Automated Report Generation: Create professional business reports and proposals from dynamic data sources using structured templates and rich text formatting.
  • Document Content Migration: Extract text and metadata from legacy .docx files into Markdown or other formats for knowledge base integration or content analysis.
  • Professional Publishing Workflows: Convert complex documents into PDF or image formats for distribution while ensuring all revisions and comments are correctly processed.

DOCX Processing

Workflow Decision Tree

  • Reading/Analyzing: Use text extraction or raw XML access
  • Creating New Document: Use docx-js (JavaScript)
  • Editing Existing: Use OOXML editing or redlining workflow

Reading Content

Text Extraction with Pandoc

# Convert to markdown with tracked changes
pandoc --track-changes=all file.docx -o output.md

Raw XML Access

# Unpack document
unzip document.docx -d unpacked/
# Key files:
# word/document.xml - Main content
# word/comments.xml - Comments
# word/media/ - Images

Creating New Documents (docx-js)

import { Document, Paragraph, TextRun, Packer } from 'docx';
import fs from 'fs';

const doc = new Document({
  sections: [{
    children: [
      new Paragraph({
        children: [
          new TextRun({ text: "Hello ", bold: true }),
          new TextRun({ text: "World", italics: true })
        ]
      })
    ]
  }]
});

const buffer = await Packer.toBuffer(doc);
fs.writeFileSync('document.docx', buffer);

Editing Existing Documents

Simple Edits

  1. Unpack: unzip doc.docx -d unpacked/
  2. Edit word/document.xml
  3. Repack: cd unpacked && zip -r ../edited.docx .

Tracked Changes (Redlining)

For professional documents, use tracked changes:

<!-- Deletion -->
<w:del w:author="Author" w:date="2025-01-01T00:00:00Z">
  <w:r><w:delText>old text</w:delText></w:r>
</w:del>

<!-- Insertion -->
<w:ins w:author="Author" w:date="2025-01-01T00:00:00Z">
  <w:r><w:t>new text</w:t></w:r>
</w:ins>

Converting to Images

# DOCX to PDF
soffice --headless --convert-to pdf document.docx

# PDF to images
pdftoppm -jpeg -r 150 document.pdf page

Best Practices

  • Use Pandoc for text extraction
  • Use docx-js for creating new documents
  • For legal/business docs, always use tracked changes
  • Preserve original RSIDs when editing
