MAS Data Finder

Google Maps lead finder with website contact enrichment, optional email-domain verification, and real Excel export.

MAS Data Finder turns Google Maps into a lead list. Search inside the extension — keyword, location and range in kilometres — and it opens Google Maps, reads the results and enriches every business with the contact details published on its website. Everything lands in a clean dashboard and exports to a branded Excel file (with filters) or CSV. WHAT YOU GET FOR EVERY BUSINESS • Name, category, address and Google Maps link • Phone numbers from Maps and from the business website • Public email addresses found on the website (with optional domain verification) • WhatsApp link and Zalo link (real links found on the website, or built from the phone number and honestly labelled) • Social links (Facebook, Instagram, TikTok and more) • Rating, review count and a 0–100 quality score with the reasons behind it • Distance from your search centre — with a self-check that corrects the centre when a typed place name resolves to the wrong city POWER FEATURES • Campaigns: queue up to 10 searches (keyword | location | km, one per line) — they run one after another into a single sheet • History: businesses you already collected are skipped automatically on the next run, so every export contains fresh leads only • Keyword & location suggestions, including Vietnamese business terms and places • Excel export carries header filters, the MAS Data Finder brand band and frozen header rows; CSV export included • Dashboard with search, filters (with email, no website, hot leads) and selected-only export MADE FOR VIETNAM AND BEYOND The interface speaks English and Vietnamese. Vietnamese search terms, +84 phone numbers, Zalo contacts, provinces and districts are all handled properly — and the same tool works for any country on Google Maps. PRIVATE BY DESIGN MAS Data Finder has no account, no server and no tracking. Your leads stay in your own browser on your own computer. The extension only reads publicly displayed business information, and only when you start a search. Founder: Muhammad Amir
