About this tool

Search and replace text with optional regular expressions, all in your browser.

Can I use regular expressions?

Yes, enable regex to treat the find field as a pattern with capture groups like $1 in the replacement.

What happens with an invalid pattern?

If the regex is invalid, an error message appears and the output keeps the last valid result.
