Regex Cheat Sheet
How it works
Parsing and encoding run entirely in JavaScript here—no server sees your pasted content unless a tool explicitly says it fetches remote data.
Quick tips
- Start with a minimal sample so errors are easier to pinpoint.
- Apply one transform at a time and verify each intermediate result.
- Copy output from the tool instead of manually retyping values.
Use this tool for
- Formatting or minifying snippets before pasting into a repo or ticket.
- Checking encodings (Base64, hex, URL) without third-party paste services.
- One-off developer checks during debugging.
