Find and Replace Text Online
Instantly find and replace words, phrases, or patterns in your text. Supports case-sensitive matching, whole word search, and regular expressions. Free and private — your text never leaves your browser.
Find and replace is a fundamental text editing operation that lets you search for a specific word, phrase, or pattern within a body of text and substitute it with something else. It is one of the most commonly used features in word processors, code editors, and spreadsheet applications because it saves enormous amounts of time compared to manual editing.
Our free online find and replace tool brings this essential capability directly to your browser. Whether you need to correct a misspelled name across an entire document, swap out outdated terminology, or reformat data exported from a database, this tool handles it in seconds. You can process thousands of lines of text with a single click instead of scrolling through pages to make changes one by one.
Beyond simple text swaps, the tool supports advanced options such as case-sensitive matching, whole word boundaries, and full regular expression syntax. Case-sensitive mode ensures that "Apple" and "apple" are treated as distinct strings, which is critical when editing code or formal documents. Whole word matching prevents partial replacements — searching for "cat" will not accidentally alter "category" or "concatenate." Regular expressions unlock powerful pattern-based replacements, allowing you to match email addresses, phone numbers, dates, or any structured text pattern.
Everything runs entirely in your browser. Your text is never uploaded to a server, making it safe for confidential content such as contracts, personal notes, or proprietary source code.
- 1Paste your text: Copy the text you want to edit and paste it into the large input area at the top of the tool. You can also type directly.

Is my text uploaded to a server?
No. All find and replace operations happen entirely inside your browser using JavaScript. Your text is never sent to any server, which makes this tool completely safe for confidential or sensitive content.
Does it support regular expressions?
Yes. Click the "Use Regex" toggle to enable full JavaScript regular expression syntax. This lets you match complex patterns such as email addresses, phone numbers, dates, or any structured text using capture groups, quantifiers, and character classes.
Can I replace multiple different terms at once?
You can replace one term at a time. To replace multiple different terms, perform one replacement, then update the Find and Replace fields and run it again on the result. With regex enabled, you can use alternation (e.g., cat|dog) to match several terms in a single pass.
How does case-sensitive matching work?
By default, the tool ignores letter case, so searching for "hello" will also match "Hello" and "HELLO." When you enable Case Sensitive mode, only exact case matches are found and replaced, giving you precise control over your substitutions.
Can I undo a replacement?
The original text remains in the input field and is never overwritten, so you always have your source content available. If you want to start over, click "Clear All" to reset every field. You can also simply modify the Find or Replace values and the result updates instantly.
