Why use a JSON Formatter?

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. However, when JSON is transmitted over networks, it is often minified (all whitespace removed) to save bandwidth.

Our JSON formatter securely parses your string locally in your browser to restore indentation and readability, without ever sending your sensitive data to our servers.
