EasyPattern Helper

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) - read more below.
