What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is widely used for transmitting data in web applications.

What does a JSON formatter do?

A JSON formatter beautifies raw JSON data, making it easier to read and debug. It also helps validate and minify JSON for efficient storage and transmission.

How to validate JSON

To validate JSON, simply parse it using a tool or code. If parsing succeeds, the JSON is valid. If it fails, an error message will indicate the problem.

How to format JSON

Formatting JSON means adding indentation and line breaks to make the data structure clear. Use the Format button above to beautify your JSON instantly.
