Regex Formatter
Format, test, and visualize regular expressions with match highlighting
Regex Testing Tips
- Use named capture groups (?<name>...) for more readable patterns in complex regexes.
- Test edge cases: empty strings, special characters, and boundary conditions.
- Enable the global (g) flag to find all matches, or disable it to test just the first match.
