JSON and YAML are the two most popular data serialization formats in modern software engineering. While JSON is the standard for web APIs and browser communication, YAML is favored for configuration files such as Kubernetes manifests, Docker Compose files, CI/CD pipelines (GitHub Actions, GitLab CI), and Ansible playbooks due to its clean, comment-friendly indentation syntax. Converting between the two allows seamless integration between APIs and infrastructure tools.
