Frequently Asked Questions

Can I use capture groups (like $1)?
Yes. Capture group references like $1 and $& (the whole match) are supported. Preview the result on screen to confirm the pattern behaves as intended.
Is it safe to process large amounts of text?
All processing happens in your browser, so the text you edit is never sent externally — even logs with sensitive content can be tidied safely.
