Powerful find and replace
This find and replace tool lets you search for any text pattern and replace all occurrences at once. It is ideal for cleaning up large documents, fixing repeated typos, renaming variables in code, or reformatting data. Unlike simple Ctrl+H in a text editor, this tool offers regex support for advanced pattern matching.
Options explained
Case sensitive ensures "Hello" and "hello" are treated differently. Whole word prevents partial matches — searching for "cat" won't match "category". Regular expression mode lets you use patterns like \d+ to match numbers or \b\w+@\w+\.\w+\b to match email addresses.
Runs locally
All find-and-replace operations happen in your browser. Your text is never transmitted to any server, making this tool safe for sensitive content.
