Edit, validate and transform your JSON data in seconds.
Everything is processed in your browser. Your data never leaves your device.
JSON is a lightweight, human-readable data interchange format. It is built on two structures: a collection of key-value pairs (objects) and an ordered list of values (arrays). It is widely used in APIs, web applications and configuration storage.
Format applies indentation and line breaks to improve readability and debugging. Minify removes unnecessary whitespace to reduce size for transfer or storage. Both transformations keep the same semantic content when the JSON is valid.
A strict JSON parser does not allow trailing commas, comments or single quotes for strings. It also requires double quotes around property names. If the content does not follow these rules, the editor will show a parsing error before it can be formatted or minified.
This tool processes the content locally in your browser. It does not send your JSON to any external server, making it useful for reviewing sensitive data during development or support.
