About this extension
Effortlessly extract, validate, deduplicate, and export contact details directly from your active webpage. Built specifically for sales professionals, recruiters, growth hackers, and researchers, Email Extractor – Basic v1 turns messy web pages into clean, spreadsheet-ready contact lists with a single click.

  • Instant, One-Click Harvesting: Scans visible body text, dynamic DOM nodes, element attributes, and embedded mailto: links across the active webpage in milliseconds.
  • Intelligent Deduplication & Sanitization: Automatically normalizes uppercase/lowercase variations, strips trailing punctuation (commas, periods, brackets, quotation marks), eliminates file extensions masquerading as emails (e.g., .png, .jpg), and delivers an alphabetically organized list.
  • Real-Time Dynamic Search & Filter: Quickly narrow down extensive email lists with an instantaneous, in-popup search bar without mutating or clearing the underlying dataset.
  • Professional Export Workflows:
  • Copy All: Instantly push all unique records to your system clipboard, formatted cleanly with one email per line.
  • Download TXT: Export standard UTF-8 text documents structured for bulk email dispatchers or cold outreach campaigns.
  • Download CSV: Generate spreadsheet-compatible files complete with standard headers and UTF-8 Byte Order Mark (BOM) for seamless import into Excel, Google Sheets, or CRM databases.
  • Pure Offline Architecture & Zero-Knowledge Privacy: Operates entirely within your local browser sandbox. It makes no remote server calls, utilizes no third-party tracking scripts, collects zero telemetry, and never stores your discovered contacts.

  1. Navigate to any standard website containing directory listings, team pages, or contact rosters.
  2. Click the Email Extractor icon in your toolbar.
  3. Select Extract Emails to instantly reveal all unique contacts.
  4. Filter using the live search box or export via Copy All, Download TXT, or Download CSV.

(Note: Designed exclusively for single-page on-demand productivity. Does not bypass authenticated paywalls, solve CAPTCHAs, or conduct unauthorized background multi-page network crawling.)
