About

Paste JSON and the tool tells you if it's valid. If not, it points to the line and column where the parser choked. Faster than the full formatter when all you want is a yes or no.

How to use

  1. Paste JSON.
  2. See valid or invalid status, with the error location if invalid.

FAQ

What counts as valid JSON?+

Strict JSON. No comments, no trailing commas, no unquoted keys, no single quotes. Use the JSON formatter tool if you want lenient parsing.
