Extract Text with Regex

This tool runs your regular expression over the pasted text and lists every match. Set a capture-group number to return just that part of each match, and add flags such as i for case-insensitive.

It is like a friendly, visual grep that keeps everything in your browser.

Group 0 returns the whole match; group 1 returns the first parenthesised part, and so on. The g flag is always applied so you get every match, not just the first.

An invalid pattern shows a clear error instead of failing silently, so you can fix it as you type.

Every conversion happens locally in your browser, so your data is never uploaded, logged or stored on a server. You can use it on confidential exports without a second thought, and it keeps working offline once the page has loaded.

There is no sign-up, no watermark and no row limit: the only ceiling is your device's memory.
