description: "Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation."

DOCX creation, editing, and analysis
Overview
A .docx file is a ZIP archive containing XML files.
Quick Reference
| Task | Approach |
|---|---|
| Read/analyze content | pandoc or unpack for raw XML |
| Create new document | Use docx-js - see Creating New Documents below |
| Edit existing document | Unpack → edit XML → repack - see Editing Existing Documents below |
Converting .doc to .docx
Legacy .doc files must be converted before editing:
python scripts/office/soffice.py --headless --convert-to docx document.docReading Content
# Text extraction with tracked changes
pandoc --track-changes=all document.docx -o output.md
# Raw XML access
python scripts/office/unpack.py document.docx unpacked/Converting to Images
python scripts/office/soffice.py --headless --convert-to pdf document.docx
pdftoppm -jpeg -r 150 document.pdf pageAccepting Tracked Changes
To produce a clean document with all tracked changes accepted (requires LibreOffice):
python scripts/accept_changes.py input.docx output.docxCreating New Documents
Generate .docx files with JavaScript, then validate. Install: npm install -g docx
Setup
const { Document, Packer, Paragraph, TextRun, Table, TableRow, TableCell, ImageRun,
Header, Footer, AlignmentType, PageOrientation, LevelFormat, ExternalHyperlink,
InternalHyperlink, Bookmark, FootnoteReferenceRun, PositionalTab,
PositionalTabAlignment, PositionalTabRelativeTo, PositionalTabLeader,
TabStopType, TabStopPosition, Column, SectionType,
TableOfContents, HeadingLevel, BorderStyle, WidthType, ShadingType,
VerticalAlign, PageNumber, PageBreak } = require('docx');
const doc = new Document({ sections: [{ children: [/* content */] }] });
Packer.toBuffer(doc).then(buffer => fs.writeFileSync("doc.docx", buffer));Validation
After creating the file, validate it. If validation fails, unpack, fix the XML, and repack.
python scripts/office/validate.py doc.docxPage Size
// CRITICAL: docx-js defaults to A4, not US Letter
// Always set page size explicitly for consistent results
sections: [{
properties: {
page: {
size: {
width: 12240, // 8.5 inches in DXA
height: 15840 // 11 inches in DXA
},
margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 } // 1 inch margins
}
},
children: [/* content */]
}]Common page sizes (DXA units, 1440 DXA = 1 inch):
| Paper | Width | Height | Content Width (1" margins) |
|---|---|---|---|
| US Letter | 12,240 | 15,840 | 9,360 |
| A4 (default) | 11,906 | 16,838 | 9,026 |
Landscape orientation: docx-js swaps width/height internally, so pass portrait dimensions and let it handle the swap:
size: {
width: 12240, // Pass SHORT edge as width
height: 15840, // Pass LONG edge as height
orientation: PageOrientation.LANDSCAPE // docx-js swaps them in the XML
},
// Content width = 15840 - left margin - right margin (uses the long edge)Styles (Override Built-in Headings)
Use Arial as the default font (universally supported). Keep titles black for readability.
const doc = new Document({
styles: {
default: { document: { run: { font: "Arial", size: 24 } } }, // 12pt default
paragraphStyles: [
// IMPORTANT: Use exact IDs to override built-in styles
{ id: "Heading1", name: "Heading 1", basedOn: "Normal", next: "Normal", quickFormat: true,
run: { size: 32, bold: true, font: "Arial" },
paragraph: { spacing: { before: 240, after: 240 }, outlineLevel: 0 } }, // outlineLevel required for TOC
{ id: "Heading2", name: "Heading 2", basedOn: "Normal", next: "Normal", quickFormat: true,
run: { size: 28, bold: true, font: "Arial" },
