Hasan Email Extractor — Md. Hasan Mahmud

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.
