Instantly convert JSON to YAML in your browser. Paste JSON, get YAML — no server, no sign-up. Handles nested objects, arrays, and special characters.
What is the difference between JSON and YAML?
JSON and YAML are both data serialization formats. YAML is a superset of JSON and uses indentation instead of braces and brackets, making it more human-readable. YAML is commonly used for config files (Docker, Kubernetes, GitHub Actions) while JSON is preferred for APIs.
Does the conversion change my data?
No. The converter produces semantically equivalent YAML — all keys, values, nesting, and types are preserved exactly.
Is my JSON sent to a server?
No. Conversion runs entirely in your browser. Your data never leaves your device.
