What this does

Checks whether text is valid JSON and, if not, points to the position of the first problem — a trailing comma, a single-quoted string, a missing bracket, an unescaped control character.

When to use it

  • A program rejects a config file and the error message is unhelpful.
  • Before pasting JSON into a database field or an API console.

Good to know

Common non-JSON habits: trailing commas, comments, single quotes and unquoted keys. All four are errors in strict JSON.

Enjoy the little things in life. For one day, you may look back and realize they were the big things. Many of life's failures are people who did not realize how close they were to success when they gave up.
