A YAML to JSON converter transforms YAML configuration files into JSON format, making the data easier to process programmatically in APIs, frontend applications, and backend services. YAML is popular for DevOps and infrastructure configurations, but JSON is the most common format used for APIs, JavaScript applications, and structured data exchange.
