Extract emails from CSV, HTML or plain text — fast online email extractor
Paste any text, CSV, TSV, XML or HTML source and instantly extract every email address found. The tool works client-side (data is not stored on the server) and supports large inputs - extract up to what your browser can handle. Note: the extractor accepts copy-paste only (no automatic URL fetching).
How to use
- Paste the text or file contents (CSV/TSV/XML/HTML) into the editor.
- Click Extract -> Emails.
- All found addresses appear in the Extraction panel without modifying your original text.
- From the Extraction panel you can: Copy to clipboard, Paste to editor (replace editor content) or Append to editor (add after original text).
Supported formats & quick tips
- Plain text - paste any text and extract addresses.
- CSV - paste CSV contents. The extractor will try to auto-detect the separator (comma/semicolon). If extraction misses items, open the CSV in a text editor and paste raw contents.
- TSV - paste tab-separated data; tabs are supported as field separators.
- HTML - paste page source or HTML snippet. The extractor finds addresses in attributes, text nodes and comments.
- XML - paste raw XML; the extractor reads text values and attributes.
Examples
- Extract from CSV (multiple columns)
Input: name,email,company Alice,alice@example.com,Acme Bob,bob@example.org,OtherCo Action: Paste entire CSV, click Extract -> Emails. Extraction panel (example): alice@example.com bob@example.org - Extract from HTML
Input: <a href="mailto:info@site.com">Contact</a> <div>support@service.io</div> Action: Paste HTML source, click Extract -> Emails. Extraction panel (example): info@site.com support@service.io - Extract from TSV or mixed text
Input: john.doe@example.com 123-456-7890 no-email-here jane_smith@company.co Action: Paste text, click Extract -> Emails. Extraction panel (example): john.doe@example.com jane_smith@company.co - Large document / repeated extraction
Input: (long article, report or exported file) ...many lines... Action: Paste full contents, click Extract -> Emails. Note: Extraction panel shows all detected addresses. Use Copy to clipboard or Append to editor to create a ready list.
Extraction panel — how it works
All extracted email addresses appear in the Extraction panel. Your original editor content remains unchanged. The panel is interactive and includes three actions:
- Copy to clipboard - quickly copy the full list of extracted addresses.
- Paste to editor - replace the editor content with extracted addresses.
- Append to editor - add extracted addresses after the current editor content.
What to expect / limits
- There is no fixed server-side repetition or extraction cap - extract as much as your browser and device allow. Extremely large inputs (many megabytes or tens of thousands of addresses) can slow the browser; consider extracting in smaller chunks if necessary.
- The extractor uses pattern matching to detect common email formats. It handles most standard addresses but may miss extremely unusual or malformed addresses.
- Duplicate addresses are shown in the Extraction panel as they are found. Use the built-in Remove Duplicates tool if you need a unique list.
- For custom patterns or advanced extraction (non-standard formats), use the Pattern Extractor and run your regex over the text before or after extraction.
Tips & edge cases
- If a CSV uses a non-standard separator, open it in a text editor and paste raw contents so auto-detection can work better.
- To avoid partial matches inside larger tokens, clean the input first using Remove Line Breaks or Trim where appropriate.
- If your source includes HTML you do not want to analyze, run it through the HTML Stripper first.
- To prepare extracted addresses for import as JSON or CSV, use CSV to JSON Converter or other converters after copying the output.
FAQ
Is there a maximum input size or limit?
No fixed limit - the tool runs client-side and can process large inputs up to what your browser and device memory permit. Very large files may slow or freeze the browser; if that happens, split the input into smaller parts.
Do you fetch pages from URLs or only accept pasted content?
Only pasted content is accepted. The tool does not fetch webpages or follow links - paste the HTML source or page text you want to analyze.
Are my pasted documents stored on your server?
No. Extraction runs in your browser and the data is not stored on our servers. We process the text client-side so pasted content remains private and is not logged.
Will duplicates be removed automatically?
No - the Extraction panel shows all found addresses including duplicates. To remove duplicates, use the Remove Duplicates tool or the Remove Duplicates option in the editor.
Can I customize the detection rules or use regex?
The Email Extractor detects common email patterns automatically. For custom patterns use the Pattern Extractor, which supports regular expressions and advanced matching.
