FAQ

What is YAML?

YAML (YAML Ain’t Markup Language) is a human-readable data format used for configuration files and data exchange. It uses indentation (spaces) instead of brackets and commas, making it clean and easy to read. YAML is commonly used in DevOps tools, configuration files, and applications where clarity matters.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight, text-based data format used to store and exchange data. It represents data as key–value pairs and arrays, making it easy for both humans to read and machines to parse. JSON is language-independent but is most commonly used in web applications to send data between a client and a server.

Why convert YAML to JSON?

JSON is supported by virtually every programming language and API, while YAML is primarily used for configuration. Converting YAML to JSON lets you use config data in any JSON-based system.
