Frequently Asked Questions
How do I use regex find and replace?
Enter your regular expression pattern in the find field and the replacement text in the replace field. Use capture groups with parentheses in the pattern and reference them with $1, $2, etc. in the replacement.
What is a capture group reference?
A capture group is a part of a regex enclosed in parentheses. You can reference matched groups in the replacement string using $1 for the first group, $2 for the second, and so on, allowing dynamic replacements.
