Regex Explainer

Paste a regular expression and get a plain-language breakdown of every part — useful when you inherit a pattern you cannot read.

Your regular expression

Paste a pattern (without the slashes). Each part is explained in plain language.

Nothing explained yet

Paste a regular expression above, then press “Explain”.

This is a token-by-token breakdown, not a semantic simplification. It does not check what your pattern matches — use the Regex Tester for that.

Runs entirely in your browser. Nothing is uploaded.
