Look for text matching:
"[email protected]"

1. Tokenize input text.
2. Apply RFC 5322 compliant
   regex for candidate matching.
3. Filter candidates via
   format validation (if enabled).
4. Normalize case for
   deduplication (if enabled).
5. Apply sorting (if enabled).
6. Output to chosen format.

Frequently Asked Questions (FAQ)

Have questions about using the Email Extractor Tool or how it handles your data? Below are answers to the most common queries. This tool is built to be both powerful and user-friendly, with a strong emphasis on your privacy and data security.

Is my data safe? Where is it processed?

Absolutely. Your privacy is our top priority. All extraction processing occurs locally within your web browser using JavaScript. The text you paste or the file you upload is never transmitted over the internet to our servers or any third party. You can even use the tool offline after the initial page load.

What is the difference between "extracting" and "validating" emails?

Extraction finds all strings that look like email addresses (e.g., `[email protected]`). Validation checks if those extracted strings adhere to the formal syntax rules for email addresses (correct placement of @, valid characters, domain structure). Enabling validation removes false positives like `[email protected]` or `@domain.com`.

What file types can I upload?

The tool supports text-based files including `.txt`, `.csv`, `.html`, `.json`, `.log`, and `.md` (Markdown). For files like PDF or DOCX, please first copy and paste the text content or convert the file to a supported format like TXT.

Can I use this tool to extract emails from a website?

Yes, but indirectly. You cannot input a URL. However, you can view the website's page source code (usually via right-click and "View Page Source" in your browser), copy all that HTML code, and paste it into the tool. It will effectively find all emails, including those hidden in `mailto:` links and scripts.
