Mastros — Telegram Group Members, Chats, Contacts, Media Scraper (Excel)

Telegram scraper to export group members, contacts, messages, mutual groups & media to Excel, CSV or JSON. Read-only, local.

Telegram scraper for exporting group members, contacts, messages, mutual groups and media to Excel, CSV or JSON. Scrape and export structured data from Telegram Web and download media in original quality, all client-side in your browser. ━━━━━━━━━━━━━━━━━━━━━━━━ 🧩 FIVE SCRAPING MODES ━━━━━━━━━━━━━━━━━━━━━━━━ • Media Downloader — download photos, videos, documents and voice notes from a chat in original quality. • Group Members — export a Telegram group or channel member list (name, username, ID, bio, status). • Chat Messages — export messages from any conversation with sender, timestamp and text. • Recent Contacts — pull your recent contacts into a clean spreadsheet. • Mutual Groups — find the groups you share with a given user and download the members of them. ━━━━━━━━━━━━━━━━━━━━━━━━ ⚙️ TWO ENGINES ━━━━━━━━━━━━━━━━━━━━━━━━ • Web Mode — reads what's already rendered in Telegram Web. Zero setup, nothing to connect. • Power Mode — connect your own Telegram API credentials for faster, deeper, more complete pulls on large groups and channels. ━━━━━━━━━━━━━━━━━━━━━━━━ 📦 EXPORT YOUR WAY ━━━━━━━━━━━━━━━━━━━━━━━━ • Excel / CSV: open directly in Excel, Google Sheets, or any spreadsheet tool. • JSON / JSONL: ready for scripts, pipelines and data tools. • Media: saved to your machine in original quality. ━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY FIRST ━━━━━━━━━━━━━━━━━━━━━━━━ ✓ Read-only — no messages sent, no members added, no automation. ✓ Client-side — scraping and export happen in your browser; your data isn't shipped to us. ✓ You only ever access chats you're already a member of. ✓ Power Mode API credentials stay local to your browser. ━━━━━━━━━━━━━━━━━━━━━━━━ 👤 WHO IS THIS FOR ━━━━━━━━━━━━━━━━━━━━━━━━ Growth, community and GTM teams who need to scrape Telegram groups for outreach lists, back up their own communities, migrate member data, or analyze conversations — without copy-pasting by hand. ━━━━━━━━━━━━━━━━━━━━━━━━ 💳 PLANS ━━━━━━━━━━━━━━━━━━━━━━━━ Free to start with monthly export limits. Paid plans unlock higher limits for heavier exports — see current pricing in the extension. ━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 GETTING STARTED ━━━━━━━━━━━━━━━━━━━━━━━━ 1. Install and open Telegram Web (web.telegram.org). 2. Open the Mastros sidebar from the edge pill or the toolbar icon. 3. Pick a mode, run the scrape, and export to Excel, CSV or JSON. ━━━━━━━━━━━━━━━━━━━━━━━━ 🔑 AUTHENTICATION INFORMATION ━━━━━━━━━━━━━━━━━━━━━━━━ Web Mode needs no credentials. Power Mode is optional and uses your own Telegram API ID/hash (from my.telegram.org) to talk to Telegram's API directly from your browser for faster, more complete pulls. These credentials are stored locally and are never sent to Mastros servers. ━━━━━━━━━━━━━━━━━━━━━━━━ ⚖️ COMPLIANCE ━━━━━━━━━━━━━━━━━━━━━━━━ Not affiliated with, endorsed by, or connected to Telegram. You are responsible for lawful use of exported data and for complying with applicable privacy laws and Telegram's terms. No bulk messaging, no auto-adding, no automation — Mastros only reads and exports.
