JSON to YAML Converter
Convert JSON data to YAML format instantly.
About JSON to YAML Converter
Paste any valid JSON and get cleanly formatted YAML output. Handles nested objects, arrays, strings, numbers, booleans, and null values with proper YAML representations. Great for Kubernetes configs, GitHub Actions, and Docker Compose files.
Use Cases
Converting JSON configs to YAML for Kubernetes, transforming API responses to YAML, preparing Helm chart values files, editing OpenAPI specs in YAML format.
How It Works
Parses JSON with JSON.parse(), then recursively converts each value to YAML syntax: objects become indented key-value pairs, arrays become dash-prefixed lists, strings are quoted where necessary.
Frequently Asked Questions
Are YAML and JSON interchangeable?
YAML is a superset of JSON — all valid JSON is valid YAML. But YAML supports more features like comments, anchors, and multi-line strings.
Does the converter support YAML anchors?
No. It converts JSON values to standard YAML key-value pairs. Anchors and aliases are a YAML-specific feature that require manual authoring.
