info About this tool
Convert JSON data to YAML format for easier reading and editing. Perfect for Kubernetes configs, Docker Compose files, and CI/CD pipelines.

File size: YAML output is typically 10–20% smaller than the source JSON, since YAML omits quotes and brackets on simple values.

Quality: JSON keys are always quoted in JSON but unquoted in YAML when they contain only alphanumeric characters. The output uses 2-space indentation.
