What does valid JSON require?
JSON requires double-quoted property names and strings, valid commas and brackets, and supported value types such as strings, numbers, booleans, null, arrays, and objects. This tool uses the browser's native JSON parser, so invalid syntax is rejected before formatting or minifying.
