What is YAML to JSON conversion?

YAML (YAML Ain't Markup Language) is a human-readable data serialization standard often used for configuration files. JSON (JavaScript Object Notation) is a lightweight data-interchange format. Converting between them is essential for developers working with Kubernetes, Docker Compose, or configuration management tools who need to interface with APIs or JavaScript applications.
