Tip: Escape special characters with a backslash: \. matches a dot, \d a digit, \s a space.
Questions
Which regex flavour is this?
JavaScript's (the same as in browsers and Node.js). Most patterns work the same in Python, PHP and Java.
Why does my pattern match only once?
Add the g flag to find every match.
Is my data uploaded?
No. The tool runs in your browser; what you paste or open never leaves your device and nothing is stored on a server.
