Format guide
JSON
JavaScript Object Notation
JSON is a lightweight text format for structured data, nested objects, arrays, strings, numbers, booleans. It's the lingua franca of web APIs, configuration files, and data interchange between programs. Human-readable when formatted, machine-parseable in every programming language, and roughly half the size of equivalent XML.
How to open a JSON file
Any text editor reads JSON. Browsers display .json files in a formatted tree view. VS Code and similar editors highlight syntax.
Primary use
API responses, configuration files, structured data interchange.
