About this tool

Update repeated wording in a draft or remove a fixed fragment from copied data before using it elsewhere.

How to use

Paste text, enter what to find and type the replacement. Leave the replacement empty to delete matches. Enable case matching or whole-word matching as needed; the output updates automatically.

Search and replacement are literal strings, so characters such as . and $1 are not interpreted as expressions. Whole-word boundaries recognize Unicode letters and digits. Use the regular expression tester for regex replacements. Input limit: 2 MiB; search and replacement: 10,000 UTF-8 bytes each; output: 8 MiB.

Common questions

Are $1 and regex symbols interpreted?

No. Search and replacement are literal text. An empty replacement deletes matches; whole-word matching uses Unicode letter, mark and number boundaries.

Why does whole-word search for cat skip catalog and cat_id?

Whole-word mode rejects a match next to a Unicode letter, combining mark, number or underscore. Turn it off to replace text inside larger words or identifiers. Case sensitivity is a separate option; check it when Cat and cat should remain distinct.
