Mastros builds Chrome extensions that export Telegram, WhatsApp and LinkedIn
data to Excel (CSV).

On this channel: setup walkthroughs, feature demos and practical workflows for
each extension in the suite.

▸ Telegram scraper — export group members and channel subscribers, pull full
chat history, download shared media in bulk, five extraction modes.
▸ WhatsApp scraper — export contacts and group participants, save conversations.
▸ LinkedIn exporter — export profiles, posts, linkedin sales navigator, jobs and companies.

Built for lead generation, list building, CRM imports, community management,
research and cold outreach — without copy-pasting anything by hand.

Everything runs locally in your browser. No account, no server upload, no data
leaves your machine. Free tier on every extension.
