What is CSV to YAML Conversion?

CSV to YAML conversion turns comma-separated (or other delimiter) rows into YAML format. YAML is widely used for configuration: Kubernetes, Ansible playbooks, Docker Compose, GitHub Actions, and many CI/CD systems. Each CSV row typically becomes a YAML object in a list, or you can output a mapping keyed by the first column.
