This tool finds a specific string throughout long text or lists and replaces it with another value all at once. With regular expression and case-insensitive support, it's useful for developers and editors cleaning up code, data, and manuscripts.
How to use
- Paste your source text.
- Enter the string to find and the string to replace it with.
- Turn on 'Use regex' or 'Ignore case' if needed.
- Check the number of replacements and copy the result.
FAQ
- Can I use regex groups ($1)?
- Yes. When 'Use regex' is on, you can use group references like $1, $2 and $& (the full match) in the replacement string. In normal mode, the $ sign is output as is.
- Can I see how many were replaced?
- The 'Replacement count' above the result shows the actual number changed in real time, so you can immediately confirm whether the right number was replaced.
- Is the pasted text stored on a server?
- No. All find-and-replace runs entirely within your browser, and what you enter is never sent to a server.
