YAML

• YAML (YAML Ain't Markup Language) is a human-readable data serialization language commonly used for configuration files and data interchange.
• It features a clean syntax using indentation and is often preferred for its simplicity and readability.

JSON

• JSON (JavaScript Object Notation) is a lightweight data interchange format.
• It uses key-value pairs to represent data structures, making it easy for humans to read and write, and for machines to parse and generate.

Why Convert YAML to JSON

YAML is easy for humans to read, while JSON is widely supported by APIs, web applications, and programming languages. Converting YAML to JSON helps ensure compatibility across systems, simplifies data exchange, and makes configuration data easier to integrate into modern applications.
