Email Extractor

Q: How does the email extraction work?

Our tool uses a powerful Regular Expression (regex) to scan the input text for strings that match common email address formats. This method is very fast and effective for finding valid emails in a large body of text.

Q: Will this find every possible email address?

The tool is designed to find over 99% of all real-world email addresses. While the official email standard allows for some very obscure formats, our regex is optimized for accuracy and to prevent false positives from text that is not an email.

Q: What is the difference between Download .txt and Download .csv?

Downloading as .txt gives you a simple plain text file of the emails. Downloading as .csv creates a spreadsheet-ready file with a proper 'email' header column, which is ideal for importing into marketing or contact management software.

Q: Why is 'Force Lowercase' a useful option?

Forcing all emails to lowercase is a standard data cleaning practice. It ensures that when you remove duplicates, 'John.Doe@example.com' and 'john.doe@example.com' are correctly identified as the same address, resulting in a cleaner list.

Q: Is the text I enter private?

Yes, your data is 100% private. All text processing and email extraction happens in your browser. No data is ever sent to our servers.

Frequently Asked Questions

How does the email extraction work?

Our tool uses a powerful Regular Expression (regex) pattern designed to match the vast majority of valid email address formats. It scans the input text for any strings that match this pattern and lists them in the output. This method is fast and highly effective for most common email types.

Will this find every possible email address?

The regex we use covers over 99% of all practical, real-world email addresses. While the official standard for emails (RFC 5322) allows for some extremely unusual formats that might be missed, our tool is optimized to find all standard emails accurately and avoid false positives from other text that just happens to contain an "@" symbol.

What is the difference between Download .txt and Download .csv?

Downloading as `.txt` will give you a plain text file with one email per line (or comma-separated, depending on your selection). Downloading as `.csv` (Comma-Separated Values) will create a file designed to be opened in spreadsheet software like Excel or Google Sheets. It will automatically include a header row labeled "email".

Why is "Force Lowercase" a useful option?

While email addresses are technically case-insensitive (e.g., "John.Doe@example.com" is the same as "john.doe@example.com"), forcing them all to lowercase is a standard practice for creating clean, consistent data. It ensures that when you remove duplicates, "John.Doe@example.com" and "john.doe@example.com" are correctly treated as the same address.

Is the text I enter private?

Yes. All text processing and email extraction happens directly in your web browser. None of the content you enter is ever sent to our servers, so you can safely use this tool with sensitive information.
