JSON
JSON is a text format for representing structured data and exchanging it between systems.
JSON, or JavaScript Object Notation, is a text format for structured data. It represents objects made up of name–value pairs, arrays, strings, numbers, booleans and null. Although derived from JavaScript, it is used across programming languages.
AI services use JSON in API requests and responses and for structured model output. Unlike JSONL, a JSON file contains one complete, valid JSON value.
