EasyPattern Helper is the perfect tool for designing and testing regular expressions that match what YOU want. EP Helper continuously applies the pattern to your test string as you type - so you see matches immediately, preventing mistakes on production data.

You can use your tested pattern with thousands of tools that support perl-style patterns. Patterns can also be saved and re-loaded.

Supported Patterns

EP Helper fully supports perl-style regular expressions, and grep, egrep and fgrep regex.

EP Helper also supports EasyPatterns (which can be converted to perl regex).
