RegEx Helper is a plugin for Notepad++ that provides you with a convenient way to test and edit regular expressions.
Editing a regular expression is easy because the regex editor highlights matching braces and ignores spaces and line breaks. This allows you to format your regular expressions so they are easy to read and debug.
Testing regular expressions is easy because the plugin can highlight matches in any open document. This provides an easy way to generate test data on the fly (create a new document and type something) and it also provides a simple way to work with persistent test data (use files).
The plugin also provides a detailed view that shows the sub-patterns a regex matches which makes testing and debugging much easier.
