What does a JSON formatter do?
A JSON formatter adds indentation and line breaks so structured data is easier to read. Validation also detects malformed syntax such as missing quotes, commas or brackets.
Is my JSON uploaded?
No. This formatter uses the browser's built-in JSON parser and does not send your input to the server.
