How to export WhatsApp Web group members and chats to CSV (without the API)

Short summary

WhatsApp offers no native way to export group members or chat lists to a spreadsheet. This guide walks through three approaches: the built-in single-chat export (limited), the Meta Cloud API (powerful but heavy), and a client-side browser extension like Mastros that reads rendered DOM data for a pragmatic middle ground. The author includes practical tips on scrolling before export, using JSONL for large pulls, deduplication, and GDPR compliance.

• •WhatsApp has no native bulk export for group members or contact lists
• •Three options: built-in Export chat, Meta Cloud API, or a browser extension reading the DOM
• •Browser extension Mastros runs client-side, exports CSV/JSON/JSONL, with a free tier for small jobs
