What Is an Email Extractor?

An email extractor is a tool that automatically scans text, documents, or web pages and extracts email addresses based on recognizable patterns. Instead of searching manually, the tool quickly identifies valid emails and presents them in a clean, usable list. This email extractor online works directly in your browser with no installs required.

How to Extract Email Addresses Online (Step-by-Step)

  • Paste text or upload a file. Drop any text into the Input box, upload a .txt, .csv, .html, .json, .log, or .eml file, or load a CORS-friendly text-file URL.
  • Pick a separator. Choose how the extracted emails should be joined in the output - line break, comma, space, hyphen, tab, or semicolon.
  • Apply optional filters.
    • Remove duplicates - keep each address once.
    • Sort list - alphabetically order the results.
    • Lowercase - normalize casing for consistent dedupe.
    • HTML source mode - strip tags, decode HTML entities (@), and de-obfuscate [at] / (dot) patterns.
    • Auto update - refresh the output as you type.
  • Filter by domain. Enter comma-separated domains into Include domains (e.g. gmail.com, outlook.com) to keep only matching addresses, or Exclude domains to drop them. Subdomains match automatically.
  • Copy or export. Copy the cleaned list, or download it as TXT, CSV (email,username,domain), or JSON. The stats strip above the output shows how many addresses were found, deduplicated, and filtered.
