What is JSON?

JSON (JavaScript Object Notation) is a lightweight, open-standard file format used to store and exchange data. It uses human-readable text to represent data as attribute–value pairs and arrays. JSON is widely used in web applications as a simpler alternative to XML, especially in APIs and AJAX systems.

Its simplicity and versatility make JSON a go-to format for data exchange across various platforms and programming languages.

What is YAML?

YAML (a recursive acronym for "YAML Ain't Markup Language") is a human-readable data-serialization language. It is commonly used for configuration files and in applications where data is being stored or transmitted.

YAML targets many of the same communications applications as Extensible Markup Language (XML) but has a minimal syntax which intentionally differs from SGML.[1] It uses both Python-style indentation to indicate nesting, and a more compact format that uses [...] for lists and {...} for maps[1] so that JSON files are valid YAML 1.2
