What Is Email Extractor?

The Email Extractor scans text and pulls out all email addresses, presenting them as a clean deduplicated list. It uses a comprehensive regex pattern that matches standard email formats including those with dots, hyphens, underscores, and plus signs in the local part, and multi-level domain names. Duplicate emails are removed so each address appears only once. This is useful for extracting contact lists from documents, web pages, or any text content.

Technical Guide

The extractor uses the regex pattern /[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/g which matches RFC-compliant email addresses. The local part allows alphanumeric characters plus period, underscore, percent, plus, and hyphen. The domain part allows alphanumeric characters with hyphens and periods for subdomains, ending with a TLD of at least 2 characters. After extraction, JavaScript's Set is used for deduplication while preserving the order of first occurrence. The count of unique emails is displayed in the output header.
