What does this tool do?

Paste any JSON and it is validated instantly. Use "Format" to pretty-print it with your chosen indent, or "Minify" to strip all unnecessary whitespace into a single compact line.

How do I know if my JSON is valid?

The status indicator above the output shows valid or invalid as you type. If it is invalid, the exact parser error is shown, including what character or token caused the problem.

Does it support nested objects and arrays?

Yes. Formatting and minifying both work on JSON of any depth, including deeply nested objects and arrays.

What is the difference between formatting and minifying?

Formatting adds line breaks and indentation to make JSON easy to read. Minifying removes all of that to make the JSON as small as possible, which is useful for sending over a network or storing compactly.

Is my data sent anywhere?

No. Parsing, formatting, and minifying all happen entirely in your browser and nothing is sent to a server.

What is a JSON formatter?

A JSON formatter validates JSON and rewrites it either as readable, indented text or as a compact single line. It is the fastest way to check whether an API response or config file is well-formed, and to switch between a human-friendly and a network-friendly representation.
