Officify

Officify is a Node.js package that lets you modify Office documents in the OpenDocument Format (ODT, ODS, ODP). With Officify, you can automatically replace text placeholders, replace images, and export your documents as PDFs.

Features

• Replace placeholders in OpenDocument files (replacePlaceholders)
• Replace images in documents (replaceImages)
• Export to PDF using LibreOffice (exportPDF)

Installation

Note: Officify requires LibreOffice to be installed on your system for PDF export. Make sure soffice is available in your PATH.

npm install officify

Usage

import { Officify } from "officify";
import fs from "fs/promises";

// Load template
const buffer = await fs.readFile("template.odt");
const doc = new Officify(buffer);
await doc.load();

// Replace placeholders
await doc.replacePlaceholders({ "{{name}}": "John Doe" });

// Replace images
const img = await fs.readFile("logo.png");
doc.replaceImages({ "logo.png": img });

// Export to PDF
const pdf = await doc.exportPDF(); // all pages
const pdf = await doc.exportPDF("1-3"); // pages 1-3
await fs.writeFile("output.pdf", pdf);

// Save modified document
const newDoc = await doc.getBuffer();
await fs.writeFile("output.odt", newDoc);
