About Find / Replace
Find the first or every occurrence using literal or regular-expression matching, with case and multiline controls.
Find / Replace supports literal text and JavaScript regular expressions. Controls for case, multiline anchors, and replacing one or every match make it suitable for both simple editorial corrections and structured cleanup.

Limitations and responsible use

- A pathological expression can make the browser tab unresponsive.
- The tool works on plain text and does not preserve rich-text formatting.
Frequently asked questions
Are replacement capture groups supported?
Yes. In regex mode, JavaScript replacement tokens such as $1 can reference captured groups.
How do I replace the search text literally?
Leave regular-expression mode disabled; special characters will then be escaped automatically.
