Question 1

How do I format JSON online?

Accepted Answer

Paste your JSON into the input box and press Format. The tool re-indents it with 2, 4 or 8 spaces so it is easy to read, then you can copy the result.

Question 2

Is this JSON formatter free and private?

Accepted Answer

Yes. It is completely free with no sign-up, and all formatting happens in your browser — your JSON is never uploaded to a server.

Question 3

How do I fix a JSON syntax error?

Accepted Answer

Press Validate. If the JSON is invalid the tool shows the exact parser error message and position so you can locate the missing comma, quote or bracket.
