What is Mastros — WhatsApp Scraper?
Mastros — WhatsApp Scraper is a Chrome extension for turning WhatsApp Web chats, contacts, and groups into structured files.
It runs inside WhatsApp Web and exports the data you already have access to. There are three scrapers: Group Members (names, phone numbers when shown, and roles from an open group), Chat Messages (the loaded message history of the open chat plus its contact card), and Recent Contacts (names, previews, times, and numbers from your chat list). Download everything as CSV, JSON, or JSONL and open it in Excel, Google Sheets, or your own tools.
Everything runs client-side in your browser. Message text, phone numbers, names, and chat titles are never uploaded to Mastros servers. It is Web Mode only, with no API and no automation of any kind (no sending, auto-replies, broadcasting, joining groups, or inviting contacts). It reads only what WhatsApp Web has already rendered, so there is no deleted-message recovery and hidden numbers are never revealed.
Useful for research, analysis, community management, record keeping, and moving WhatsApp data into a spreadsheet or CRM. A free tier is available with no signup. Not affiliated with WhatsApp or Meta.
