Frequently Asked Questions
How does regex mode work?
Enable regex mode to use regular expression patterns. For example, \d+ matches numbers, \b\w+\b matches words, and [a-z]+ matches lowercase letters. Use parentheses for capture groups and $1, $2 in replacement.
What does 'whole word' matching mean?
Whole word matching only finds complete words, not partial matches. Searching for 'cat' won't match 'category' or 'concatenate'. This is useful for precise replacements.
Can I undo replacements?
The original text is preserved until you make changes. After replacing, you can clear and paste your original text again. We recommend copying important text before bulk replacements.
Is there a limit on text size?
The tool handles large texts efficiently in your browser. For extremely large files (several MB), performance may vary depending on your device.
