In short: Find and replace searches text for a word, phrase or regular expression and swaps every match for new text, with options for case sensitivity and whole words.
About Find and Replace Text
Changing a product name throughout a document, swapping a placeholder in an email template or cleaning up a CSV column are all find-and-replace jobs. This tool shows the result and the number of replacements live as you type, so you can check before copying.
In regular-expression mode, the pattern uses JavaScript syntax and the replacement can refer to capture groups with $1, $2 or $<name>; \n and \t in the replacement insert a newline or tab. Without regex mode, special characters are matched literally.
How to use Find and Replace Text
- Paste your text.
- Type what to find and what to replace it with.
- Set Match case, Whole words or Regular expression as needed, then copy the result.
Examples
Find Acme Pro, replace with Acme Max, Match case on — “acme pro” in lower case is left alone.
Find (\d{2})/(\d{2})/(\d{4}), replace with $3-$1-$2 to turn 03/14/2026 into 2026-03-14.
Frequently asked questions
Why is “cat” replaced inside “category”?
Turn on Whole words only, which only matches the word on its own.
Can I replace line breaks?
Yes, in regex mode: find \n and replace with a space or comma.
Can I undo?
The original text stays in the input box; the result appears separately, so nothing is lost.
Is my text uploaded?
No. Replacement happens in your browser. You can check this yourself: open your browser’s developer tools, switch to the Network tab and use the tool — no request carries your input.
