Office Document Generation

Status: Production Ready Last Updated: 2026-01-12 Dependencies: None (pure JavaScript libraries) Latest Versions: [email protected], [email protected], [email protected], [email protected]

Overview

Generate Microsoft Office documents and PDFs programmatically with TypeScript. All libraries are pure JavaScript with zero native dependencies, enabling universal runtime support:

*PPTX in Workers: Works for local images/data. Remote image fetching needs workaround (uses https module).

Quick Start

Installation

# Install all four (or pick what you need)
npm install docx xlsx pdf-lib pptxgenjs

Create a Word Document (30 seconds)

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

const doc = new Document({
  sections: [{
    children: [
      new Paragraph({
        children: [
          new TextRun({ text: 'Hello World', bold: true, size: 48 }),
        ],
      }),
    ],
  }],
});

// Node.js: Save to file
const buffer = await Packer.toBuffer(doc);
writeFileSync('hello.docx', buffer);

// Browser/Workers: Get as blob
const blob = await Packer.toBlob(doc);

Create an Excel Spreadsheet (30 seconds)

import * as XLSX from 'xlsx';

// Create workbook with data
const data = [
  ['Name', 'Amount', 'Date'],
  ['Invoice #1', 1500, '2026-01-12'],
  ['Invoice #2', 2300, '2026-01-13'],
];

const worksheet = XLSX.utils.aoa_to_sheet(data);
const workbook = XLSX.utils.book_new();
XLSX.utils.book_append_sheet(workbook, worksheet, 'Invoices');

// Node.js: Save to file
XLSX.writeFile(workbook, 'invoices.xlsx');

// Browser/Workers: Get as buffer
const buffer = XLSX.write(workbook, { type: 'buffer', bookType: 'xlsx' });

Create a PDF (30 seconds)

import { PDFDocument, StandardFonts, rgb } from 'pdf-lib';

const pdfDoc = await PDFDocument.create();
const page = pdfDoc.addPage([612, 792]); // Letter size
const font = await pdfDoc.embedFont(StandardFonts.Helvetica);

page.drawText('Hello World', {
  x: 50,
  y: 700,
  size: 24,
  font,
  color: rgb(0, 0, 0),
});

// Get as bytes (works everywhere)
const pdfBytes = await pdfDoc.save();

// Node.js: Save to file
writeFileSync('hello.pdf', pdfBytes);

Create a PowerPoint (30 seconds)

import pptxgen from 'pptxgenjs';

const pptx = new pptxgen();
pptx.author = 'Your Name';
pptx.title = 'Sample Presentation';

// Add a slide
const slide = pptx.addSlide();
slide.addText('Hello World', {
  x: 1, y: 1, w: 8, h: 1.5,
  fontSize: 36, bold: true, color: '363636',
});

// Node.js: Save to file
await pptx.writeFile({ fileName: 'hello.pptx' });

// Browser: Trigger download
await pptx.writeFile({ fileName: 'hello.pptx' });

DOCX: Word Documents

Key Concepts

The docx package uses a builder pattern:

• Document - The root container
• Section - Contains pages (most docs have 1 section)
• Paragraph - A line/block of text
• TextRun - Formatted text within a paragraph
• Table - Grid of TableRow → TableCell → Paragraph

Document with Headings and Paragraphs

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

const doc = new Document({
  sections: [{
    children: [
      new Paragraph({
        text: 'Monthly Report',
        heading: HeadingLevel.HEADING_1,
      }),
      new Paragraph({
        children: [
          new TextRun('This is a '),
          new TextRun({ text: 'bold', bold: true }),
          new TextRun(' and '),
          new TextRun({ text: 'italic', italics: true }),
          new TextRun(' text example.'),
        ],
      }),
    ]

1
Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
›Cursor installed and configured on your development machine
›Node.js version 16.0+ with npm package manager (verify with node --version)
›Active project directory or workspace where you want to add office
2
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
$npx skills add https://github.com/jezweb/claude-skills --skill officecopy
The skills CLI fetches office from GitHub repository jezweb/claude-skills and configures it for Cursor.

Select Cursor when prompted
The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:
◆ Which agents do you want to install to?
│
│ ── Universal (.agents/skills) ── always included ────
│   • Amp
│   • Antigravity
│   • Cline
│   • Codex
│ ●Cursor(selected)
│   • Cursor
│   • Windsurf

Verify installation
Confirm successful installation by checking the skill directory location:
.cursor/skills/office
Reload or restart Cursor to activate office. Access the skill through slash commands (e.g., /office) or your agent's skill management interface.
⚠
Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
