JSON Basics

What is {} in JSON?

In JSON, curly braces {} represent an object, which is a collection of key-value pairs. An empty object {} contains no properties and is perfectly valid JSON. Objects are fundamental structures in JSON, allowing you to group related data together. For example, {"name": "John", "age": 30} creates an object with two properties. Objects can be nested within other objects or arrays, enabling complex data structures. The opening brace { marks the start of an object, and the closing brace } marks the end. Objects must contain properly formatted key-value pairs with keys as strings in double quotes, followed by colons and values. Use our JSON Editor at jsonconsole.com/json-editor to visualize object structures in tree view, making it easier to understand nested objects and their relationships.
