Find & Replace performs single or bulk substitutions across any pasted text, with three matching modes: plain string, whole-word (word-boundary), and full JavaScript-flavor regular expressions. Regex mode supports capture groups so you can rewrite complex patterns — for example, converting `John Smith` to `Smith, John` with `(\\w+) (\\w+)` → `$2, $1`. A live match counter shows how many replacements will be made before you commit, so you never blindly overwrite the wrong text. All work happens in your browser using the built-in `String.replaceAll` and `RegExp` engines. Nothing is uploaded, which matters when the text is a contract, database dump, or unpublished draft. Batch mode lets you queue multiple find/replace pairs and apply them in order, which is useful for cleaning exported CSVs or renaming variables across a code snippet.
Free, fast, and runs entirely in your browser — no signup, no upload to a server.
