Generate Microsoft Office documents and PDFs with pure JavaScript, no native dependencies.

Create DOCX, XLSX, PDF, and PPTX files with TypeScript; all libraries run in Node.js, browsers, and Cloudflare Workers

DOCX supports paragraphs, tables, images, and text formatting; XLSX handles formulas, multiple sheets, and JSON-to-sheet conversion

PDF includes text, shapes, images, form filling, and page merging; PPTX covers slides, charts, tables, and master layouts

Common pitfalls: remember PDF coordinates start at bottom-left, always await Packer.toBuffer() for DOCX, use base64 images in Workers instead of remote URLs
