About JSON to YAML

Transform JSON into clean, human-readable YAML. YAML is widely used for configuration files (Docker Compose, Kubernetes, CI/CD pipelines, etc.) and is easier to read and edit by hand than JSON. This tool handles nested objects, arrays, and special characters.

How to use

  1. Paste your JSON into the input panel.
  2. The YAML output appears instantly in the output panel.
  3. Click Copy to copy the YAML to your clipboard.

Frequently Asked Questions

FAQs about JSON to YAML

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files. It uses indentation instead of brackets.

Is the YAML output valid?

Yes. The converter produces valid YAML that can be parsed by any YAML parser. Strings with special characters are automatically quoted.

Can I use this for Kubernetes configs?

Yes. Convert your JSON manifests to YAML format for use with kubectl and Kubernetes configuration files.

How are arrays represented?

Arrays use YAML's dash notation (- item). Nested arrays and objects are indented with 2 spaces.

Is my data safe?

Yes. All conversion happens in your browser using JavaScript. Nothing is sent to any server.
