Find and Replace (Regex)

Find and replace text in one paste — with literal matching or full JavaScript regex, case-sensitivity and whole-word toggles, multiline / dot-all / Unicode-aware flags, and capture-group references (`$1`, `$&`, `$\``) in the replacement. Watch the live match count update as you type so you know exactly what will change before you copy.

نظرة عامة على الأداة

Most online find-and-replace tools either don't support regex or hide capture groups behind a paywall. This one runs entirely in your browser, supports every flag the underlying JavaScript engine offers, and gracefully reports invalid patterns instead of silently doing nothing. Pair it with the existing Regex Tester for crafting a pattern, then bring it here to apply the replacement at scale.

حالات الاستخدام

  • Bulk-rename variables or imports across a pasted code block
  • Reformat a list of items with a regex template
  • Strip URL parameters across many lines at once
  • Replace placeholder values in an email template
  • Convert date formats with capture groups (e.g., 2024-01-15 → 15/01/2024)

الأسئلة الشائعة

What regex flavor is this?+
JavaScript regex. Everything supported by V8 / SpiderMonkey works — lookbehind, named groups, Unicode property escapes, etc.
Can I reference capture groups in the replacement?+
Yes. $1 through $9 are capture groups, $& is the whole match, $` is text before, $' is text after, and $$ is a literal dollar sign.
Why is 'Whole word' disabled in regex mode?+
In regex mode you can add `\b...\b` yourself for precise control. The whole-word checkbox is a convenience for literal mode.
Will it stop on infinite-loop regex patterns?+
Yes — the engine guards against zero-width matches so a pattern that matches the empty string doesn't lock the page.
