JRegexpTester is a standalone Swing software that helps you test regular expressions with the Sun Java standard API (java.util.regex). The extracted data can be modified with formatters similar to those used by sprintf, or with standard Java date and decimal formatters. It features RegExLib library integration with more than 900 patterns.

JRegexpTester provides the following features :
1. easy-to-use interface.
2. immediate response.
3. large file extraction permitted (line by line).
4. automatic integration of the entire RegExLib.com library (more than 1000 patterns ready to use except those .Net specific).
5. save/load/export(text,html)/search
6. users can easily see all the groups capturing text moving the cursor into the pane of details.
7. the open-close brackets (curly and square) and parenthesis are clearly highlighted into the regexp text area.
8. easy CSV file management (extract/transform). JRegexpTester can help you manage files with more than 65536 rows which can't be read entirely by Gnumeric.

A regular expression (abbreviated as regexp, regex or by some regxp) is a string that describes a whole set of strings, according to certain syntax rules. These expressions are used by many text editors and utilities (especially in the Unix operating system) to search bodies of text for certain patterns and, for example, replace the found strings with a certain other string.
