Find & Replace Tool

Paste your text, enter what you want to find and what to replace it with, then click "Replace All". Supports case-sensitive matching, whole-word matching and full regex patterns — all calculated instantly in your browser.

How to Use the Find & Replace Tool

Paste or type your text into the main box.
Enter the word, phrase or pattern to search for in "Find", and what it should become in "Replace With".
Turn on "Case-sensitive matching" if uppercase and lowercase should be treated differently.
Turn on "Whole word only" to avoid matching a search term that appears inside a longer word.
Turn on "Use regex pattern" if you need advanced matching with regular expression syntax.
Click "Replace All" to see the updated text and a count of how many replacements were made, then click "Copy".

Why Use This Tool?

Is my text uploaded anywhere?

No. Every search and replace operation runs locally in your browser using JavaScript's built-in regular expression engine. Your text — whether it's a manuscript, contract, or internal document — is never sent to a server, logged, or stored anywhere.

What does "whole word only" actually do?

Without it, searching for "cat" would also match the "cat" inside "category" or "concatenate." Turning on "Whole word only" wraps your search term with word-boundary markers so it only matches when the term stands as a complete word on its own, giving you much more precise replacements in prose or code.

What is regex mode for, and is it safe to use?

Regex (regular expression) mode lets power users search using patterns instead of exact text — for example \d+ to match any run of digits, or colou?r to match both "color" and "colour" at once. If your pattern is invalid, the tool shows a friendly error instead of breaking, so it's safe to experiment. Leave this box unchecked if you just want plain literal text matching.

Who uses a find and replace tool?

Writers and editors updating a character or product name throughout a manuscript, developers renaming variables or fixing repeated typos across a code snippet, and marketers swapping placeholder text in bulk email templates all rely on find and replace to make consistent edits in seconds instead of scanning line by line.
