About .JSON

JSON is a lightweight, text-based, language-independent data interchange format defined by standards such as RFC 8259 and ECMA-404. A JSON document is typically built from objects (key/value pairs) and arrays, with strict syntax rules (for example, strings use double quotes). The official media type for JSON is application/json.

.json files store structured data as plain text using the JSON (JavaScript Object Notation) format. They’re commonly used for web APIs, app configuration, and data exchange, and can be opened with any text editor or JSON-aware tools.
