Tidy, validate or minify JSON, with any errors explained in plain words.
Your tidy JSON appears here.
Paste messy JSON and get it back tidy and readable, or minified down to a single line. If something is wrong, you get a plain-English message pointing at the problem instead of a silent failure.
No. Formatting and validation run entirely in your browser, so you can safely paste sensitive data.
That's the whole list. A short note when there's something new worth your time. Leave whenever you like.
