I used to spend hours trying to craft the perfect expression for my scraping projects not realizing that I don't really know regex. This tool is a cheat sheet that also explains the commonly used expressions so that you understand it. - There is a visual representation of the regular expression (thanks to regexpr) - The application shows matching strings which you can play around - Expressions can be edited and these are instantly validated
