🔍 Find and Replace Text

What is Find and Replace?

Find and Replace is a powerful text manipulation tool that searches for specific text patterns and replaces them with different text across large documents instantly. Whether you're editing code, cleaning up data, reformatting documents, or removing sensitive information, our tool makes bulk text editing effortless and error-free.

Our advanced find and replace tool works entirely in your browser, ensuring your data remains completely private and secure. It supports regular expressions (regex) for complex pattern matching, case-sensitive searching for precise matches, and whole word matching to avoid partial replacements. Perfect for developers, writers, data analysts, content editors, and anyone who needs to manipulate text efficiently.

Unlike basic text editors, our tool provides real-time statistics showing character count, word count, and the number of replacements made. This helps you verify your changes before copying or using the transformed text. All processing happens locally in your browser with no server uploads, making it fast, secure, and private.

Frequently Asked Questions

Is this find and replace tool completely free?

Yes! Our find and replace tool is 100% free with no limitations, no signup required, and unlimited use. You can replace text in documents of any size, as many times as you need, without any restrictions or premium features.

Is my text data safe and private?

Absolutely! All text processing happens entirely in your browser using JavaScript. Your text never leaves your device and is not uploaded to any server. We don't store, track, log, or transmit your text anywhere. Your privacy is completely protected.

How do I use regular expressions (regex)?

Enable the "Use Regex" checkbox and enter regex patterns in the Find field. For example, use \d{3}-\d{3}-\d{4} to match phone numbers, or \b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}\b to match email addresses. See the Key Features section above for common regex patterns.

What's the difference between case sensitive and case insensitive?

Case sensitive matching requires exact capitalization - "Cat" and "cat" are treated as different words. Case insensitive matching ignores capitalization differences - "Cat", "cat", and "CAT" are all treated as the same word. Use case sensitive for precise replacements in code or formal documents.

How does "Whole Words Only" work?

Whole Words Only matches complete words surrounded by word boundaries (spaces, punctuation, start/end of line). For example, finding "cat" with Whole Words Only will match "The cat sat" but NOT "category" or "scatter". This prevents unwanted partial replacements.

Can I delete text instead of replacing it?

Yes! Leave the "Replace With" field empty to delete all matches. This is useful for removing unwanted characters, markers (like [DRAFT]), formatting codes, or any text you want to eliminate from your document.

How do I replace line breaks or newlines?

Enable "Use Regex" and use \n to match line breaks. For example, find \n and replace with a space to convert multi-line text to single line. Or find \n\n to match double line breaks (paragraph separators).

Can I undo a replacement?

Your original text remains in the input field, so you can always modify your find/replace terms and try again. The output field shows the result without modifying your original input. Copy the result only when you're satisfied with the changes.

What's the maximum text size I can process?

There's no hard limit on text size. The tool can handle documents with millions of characters. However, extremely large texts may take a moment to process depending on your device's performance. Most documents process instantly.

How do I match special characters like . or * or $?

In regex mode, special characters like . * + ? ^ $ { } [ ] ( ) | \ have special meanings. To match them literally, escape them with a backslash. For example, use \. to match a period, or \$ to match a dollar sign.

Can I replace multiple different terms at once?

Currently, the tool replaces one pattern at a time. To replace multiple terms, perform multiple find and replace operations. The output of one operation can be copied back to the input for the next replacement.

How do I replace text only at the start or end of lines?

Enable "Use Regex" and use ^ to match the start of a line, or $ to match the end. For example, find ^# to match lines starting with #, or find ;$ to match lines ending with semicolon.

Does the tool work on mobile devices?

Yes! The tool is fully responsive and works perfectly on smartphones and tablets. The interface adapts to your screen size for comfortable use on any device.

Can I use this for code refactoring?

Absolutely! The tool is perfect for renaming variables, updating function names, changing API endpoints, or any bulk code editing. Use case-sensitive and whole words options for precise code replacements. The monospace font makes code easy to read.

How do I replace tabs with spaces?

Enable "Use Regex" and find \t (which matches tab characters). Replace with the number of spaces you want (e.g., 4 spaces). This is useful for converting code indentation.

Can I use this tool offline?

Yes! After the page loads initially, all find and replace operations work offline. The tool uses client-side JavaScript, so you don't need an internet connection once the page is loaded. Perfect for working with sensitive documents.
