JSON ↔ YAML Converter
Convert between JSON and YAML formats instantly in your browser.
Frequently Asked Questions
What is YAML?
YAML (YAML Ain't Markup Language) is a human-readable data serialisation format commonly used for configuration files, CI/CD pipelines, and Kubernetes manifests.
Is the conversion done in my browser?
Yes — everything runs 100 % client-side. Your data never leaves your device, so it's safe to paste sensitive configuration.
Does this tool support all YAML features?
This converter handles the most common YAML features: key-value mappings, nested objects, arrays, scalars, quoted strings, multiline strings (| and >), and inline JSON. Some advanced features like anchors (&) and aliases (*) are not supported.
Why would I convert JSON to YAML?
YAML is easier to read and edit by hand, which makes it popular for configuration files in Docker Compose, GitHub Actions, Ansible, and Kubernetes.
Can I convert YAML with comments?
Comments (lines starting with #) are ignored during YAML → JSON conversion, as JSON does not support comments.
