Export WhatsApp Web Group Members and Chats to CSV
A practical how-to showing ways to export visible WhatsApp Web data (group members, loaded messages, recent contacts) into CSV or JSON without using the official API. The article explains built-in Export chat (TXT), the WhatsApp Business Cloud API (enterprise-level, requires Meta developer account and setup), and a pragmatic browser-extension approach that reads the rendered DOM client-side. It highlights limits: you can only export data that WhatsApp shows (no hidden phone numbers, deleted messages, or chats you are not in) and gives usage tips (scroll to load history, use JSONL for large exports, respect GDPR). The author mentions a Chrome extension called Mastros that runs client-side and offers CSV/JSON/JSONL exports.
Practical user-level guide for exporting messaging data; useful for operators of communities or CRM workflows but has limited strategic impact on the broader AdTech/MarTech industry.

Key Takeaways & Evidence Grounding
- You can only export data visible in WhatsApp Web: rendered group members, loaded messages, and visible contact info.
- Built-in Export chat produces a .txt file for a single conversation and is unstructured.
- WhatsApp Business Cloud API is the enterprise option but requires a Meta developer account, verified business, a dedicated phone number, and engineering work.
- A browser extension can read WhatsApp Web's DOM client-side and export CSV, JSON, or JSONL without sending data off-device; the author cites a Chrome extension called Mastros.
- Exports will not include hidden phone numbers, deleted messages, chats/groups you are not a member of, or message history not loaded by scrolling.

Turning WhatsApp Chats into Illustrated Comics
Chat Comics describes a production pipeline that converts exported WhatsApp chat text files into illustrated comics using LLM-driven narrative extraction and image generation. The pipeline includes parsing/normalization of varied WhatsApp export formats, passing cleaned conversations to Claude to extract themes, character archetypes, dramatic beats and panel descriptions, generating consistent character designs and expression variants, and composing scene and panel illustrations with a propagated style token. The product supports 12 distinct genre 'moods' (e.g., funny, horror, romance) that change prompts and visual parameters. Privacy measures are emphasized: uploads are processed in memory and deleted after generation, chat content is not used to train models, and minimal metadata is retained. A free first-comic tier requires no account.
How to Export Telegram Group Members and Media
This technical how-to explains practical ways to export member lists and bulk media from Telegram groups and channels. It contrasts Telegram Desktop's full-account export with API-based approaches that use MTProto to page participants and download media with preserved metadata. The author recommends using libraries (e.g., GramJS, Telethon) or a commercial extension (Mastros) in API mode with your api_id/api_hash from my.telegram.org, and warns about respecting Telegram rate limits (FLOOD_WAIT) and only exporting data your account can access. Output formats suggested include JSONL for large lists and CSV for spreadsheet use.
