Tips

• When using regex, use parentheses () to capture groups, reference them in replacement text with $1, $2, etc.

• Uncheck "Global Replace" to replace only the first match
• Use "Case Sensitive" option for exact case matching

Frequently Asked Questions

1. What's the difference between regex and normal replacement?

Normal replacement matches exact text strings, while regular expressions use pattern matching and support more complex search rules, such as matching numbers, emails, or text in specific formats.

2. How do I replace line breaks?

In regex mode, use \n to match newline characters and \r to match carriage returns.

3. Why isn't my regex working?

Check if your regex syntax is correct. Common errors include: unescaped special characters, mismatched parentheses, or unsupported syntax. Test your expression in a regex tester first.

4. Is my data safe?

Absolutely! All replacement operations are performed locally in your browser. No data is uploaded to servers, and we don't store or record any of your data.

5. Can I undo a replacement?

The original text remains in the input box, and you can modify the find and replace conditions to re-execute at any time. We recommend copying and saving the original text before replacing.
