About JSON Formatting

JSON (JavaScript Object Notation) is a common format for exchanging structured data between systems and APIs.

Formatting JSON helps you read and debug nested objects more easily, while minifying JSON reduces payload size for transport and storage.

Use this tool to quickly validate syntax, normalize indentation, and optionally sort object keys.
