Maybe for community management, marketing outreach, or just backing up your group members?</p> <p>I built <strong>WhatsApp Contact Extractor</strong> - a free, open-source JavaScript tool that does exactly this. No extensions, no installs, no sign-ups.</p> <h2> How It Works </h2> <ol> <li>Open WhatsApp Web and navigate to your group</li> <li>Open the members panel (click the group name)</li> <li>Open browser DevTools (F12) and paste the script</li> <li>Wait 1-3 minutes while it scrolls and extracts</li> <li>A <code>.tsv</code> file downloads automatically</li> </ol> <h2> What You Get </h2> <p>A clean spreadsheet with:</p> <ul> <li>Phone numbers</li> <li>Saved contact names</li> <li>WhatsApp display names</li> </ul> <h2> Why I Built This </h2> <p>Existing tools either cost money, require browser extensions (security risk), or send your data to external servers. This tool is:</p> <ul> <li> <strong>100% client-side</strong> - your data never leaves your browser</li> <li> <strong>Zero dependencies</strong> - just one JS file</li> <li> <strong>Free and open source</strong> - MIT licensed</li> </ul> <h2> Try It Out </h2> <p>GitHub: <a href="https://github.com/Mb-hunt/WhatsApp-Contact-Extractor" rel="noopener noreferrer">https://github.com/Mb-hunt/WhatsApp-Contact-Extractor</a></p> <p>Star it if you find it useful, and contributions are welcome!</p> javascript opensource webdev productivity
