I am looking free program (ok if closed source) that can:

  • create regular expressions with a GUI (i.e. the user don't have to deal with the regular expression syntax at al)
  • work on Windows 7 SP1 x64 Ultimate

Ideally, I would like to be able in which programming language the regexp will be used, as there exist different regular expression standards (more precisely the POSIX standard isn't always respected)

RegexMagic would work except that it isn't free:

www.txt2re.com may be one to look into.

It seems to handle what you are looking for (create it with a web GUI, and provide it in a slew of programming languages).


Expresso Regular Expression Tool has an expression builder:

and built-in libraries:

Perhaps this is what you are looking for?


Not a windows app, but if that isn't a barrier to you, I'd recommend Regex101.com - it does allow you to switch between pcre/javascript/python/golang flavours, if that helps.

  • This is the only one of the many recommendations among the linked threads that is still updated. A bit crammed, but does the job and even has a substitution tester also to test backreferences.
