About the Find and Replace

Finds every occurrence of a word or pattern in your text and replaces it, with optional whole-word and regex matching.

Writers use it to swap a name or term throughout a whole document in one pass, while developers use the regex option for pattern-based cleanup of code or data. Among Toolapt's collection of free text tools, this one included, there's no account to set up and no restriction on repeat use.

FAQ

Frequently asked questions

Quick answers to common questions about the Find and Replace.

What does Find and Replace do?

It searches your text for a word or pattern and replaces every match (or just the first one) with replacement text you choose.

Is Find and Replace free to use?

Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.

Is my text safe when I use this tool?

Yes. Your text is processed entirely on your own device — nothing is sent to a server.

What does "Whole words only" do?

It only matches the search term when it appears as a complete word, so searching for "cat" won't also match the "cat" inside "category".

What does "Treat Find as a regular expression" do?

It lets you use regular-expression syntax in the Find field for pattern-based matching instead of a plain literal search term.

What happens if my regular expression is invalid?

The tool shows a message telling you the expression couldn't be parsed, so you can fix it before trying again.

Can I replace only the first match instead of all of them?

Yes. Turn off "Replace every match" to replace only the first occurrence.

Does Find and Replace have any limitations?

It's built for everyday text; extremely long input or very complex regular expressions may take a moment longer to process.
