Regular Expressions Helper

Fast and simple: copy/paste text into the top box, type in a regular expression, and replace (or remove) all matches. Then copy/paste the results from the bottom box.


  • Check-as-you-type regexp matching
  • Live preview of replacement, constantly updated
  • Immediate feedback on errors, number of matches, etc
  • Copy/paste your text straight into the app
  • …or Drag/drop a file into the app to use that for the input

Upcoming features…

Here’s some features we’re working on for the future versions:

  • Interactive help on regexp syntax
  • Save multiple regexps in a “set”, and then apply the whole set with just one click (each runs one after the other)
  • …other requests you send us?
