What Is a Domain Extractor?

A domain extractor pulls the domain name out of a longer piece of text, such as an email address or a web link. Instead of manually copying "example.com" out of every row in a spreadsheet, the tool reads through your list and returns just the domains — ready to sort, deduplicate, and export.

Extract Domains from Email Addresses

Paste a list of email addresses and the tool takes everything after the @ symbol to return the domain. This is useful for grouping contacts by company, spotting which free email providers show up most often in a list, or cleaning a mailing list before an outreach campaign.

Extract Domains from URLs

Paste full links and the tool strips away the protocol, path, query string, and any fragment, leaving just the hostname. You can choose to keep the full hostname, including subdomains, or reduce everything down to the root domain — handy when you are comparing links from the same website that point to different pages.

Extract Domains from CSV and Excel Files

Upload a CSV or XLSX file directly and the tool reads the rows and columns in your browser, extracts domains from every cell that contains an email or a URL, and keeps the original row numbers so you can trace each result back to its source. Nothing is uploaded to a server — the file never leaves your device.

Why Use This Domain Extractor?

It handles messy, real-world data: mixed emails and URLs, extra spaces, different separators, and large lists. Results can be deduplicated, sorted, searched, and exported as TXT or CSV in a couple of clicks, all without an account, an API key, or a paid subscription.
