About this Domain Extractor
Domain Extractor finds URLs in your input and pulls out the hostname portion (for example, https://sub.example.com/path → sub.example.com).
This is useful for website audits, link cleanup, and turning URL lists into domain lists. If you paste bare domains without protocol, add https:// to improve detection.
