RegexBuddy makes it easier than ever for you to create regular expressions that do what you intend, without any guesswork. Still, you need to test your regex patterns to be 100% sure that they match what you want, and don't match what you don't want. RegexBuddy makes debugging regular expressions practical and safe.
Don't risk actual data with untested regexes. Copy and paste sample data into RegexBuddy, or open test files. Step through the search matches in the sample data, and get a detailed report about each match. Or highlight all matches to test the regex in real time as you edit it.
When you plan to use a regex in a search-and-replace operation, preview the search and replace in RegexBuddy. If you want to split a string using a regex, check the result in RegexBuddy. Avoid nasty surprises when using a regular expression to modify real data or files.
If the regular expression doesn't work the way you expect, click the debug button to see exactly how the regex match is found or attempted. RegexBuddy eliminates all guesswork.
"First of all fantastic tool! Better than anything else currently out there that I've tried. The fast real-time match highlighting is so productive! And a great informative tutorial too."
