About this ToolHow it works, benefits & use casesTap to collapse
Find and Replace goes well past a basic search-and-swap. Enter what to find and what to replace it with, and a live preview highlights every match in the text as you type, with a running match count and a per-line match list. Plain mode supports case-sensitive matching, whole-word matching, replace-first-only, and interpreting \n and \t escapes in the replacement so you can insert real newlines and tabs. Switch on regular-expression mode to use full JavaScript regex with the multiline (^ $), dotall (. matches newline), and unicode flags, plus capture-group replacements like $1 and named groups like $<name>. Invalid patterns are reported inline instead of throwing, so you can fix them as you go. A Swap button exchanges the find and replace fields. The result downloads as a .txt file and the entire setup — text, pattern, replacement, and every option — is captured in a shareable URL. Everything runs in your browser.
How to Use
- 1Type the text to search for in "Find" and the replacement in "Replace with" (use "Swap" to exchange them).
- 2In "Options", toggle case sensitivity, whole word, replace-first-only, and \n / \t escape interpretation.
- 3Enable "Use regular expression" to unlock the multiline, dotall, and unicode flags and capture-group replacements.
- 4Paste your text into the input box, or click "Load example" — matches are highlighted live with a count.
- 5Click "Replace" and copy or download the result, or copy the page URL to share the exact find/replace setup.

Regex mode uses JavaScript regular expressions and exposes the multiline flag (so ^ and $ match line boundaries), the dotall flag (so . matches newlines), and the unicode flag. Replacements support native capture-group references such as $1 and named groups like $<name>. Case-insensitive matching is controlled by the "Case sensitive" checkbox.
The tool never crashes on a bad pattern. Instead it shows the error message inline and leaves your text untouched until the pattern is valid. This lets you build up a complex expression incrementally and see the moment it starts matching correctly.
