About Domain Cleaner
How do I extract domain names from messy text?
The Domain Cleaner pulls every domain name out of pasted text: URLs, emails, spreadsheets, or whole web pages. It checks each one against the official list of extensions, removes duplicates, can drop registrar and popular-site domains, and returns a sorted, clean list. It runs entirely in your browser. Nothing is uploaded.
How to use it
- Paste any text that contains domain names.
- Choose whether to filter out registrar and popular sites, and whether to keep subdomains.
- Copy the clean list or export it to CSV.
Data and limits
- Where it runs
- In your browser, in a background worker. The text never leaves your device.
- Validation
- The IANA list of extensions plus the Public Suffix List, so names like example.co.uk come out whole.
- Cost
- Free. No account and no verification step.
Questions
Does the Domain Cleaner upload my text?
No. Extraction runs in your browser. The only file it downloads is the list of valid extensions.
Which domains does the popular-site filter remove?
About 160 registrar, marketplace, and large-platform domains that turn up in pasted pages, such as registrars and social networks.
What should I do with the clean list?
Check registration details in RDAP Lookup, compare it with another list in Compare Domains, or analyze it in Portfolio Summary.
