JSON → YAML Converter

Convert JSON data to YAML format.

JSON Input
YAML Output
About This Tool
The JSON to YAML converter transforms JSON data into the human-readable YAML format. JSON objects become YAML mappings, arrays become dash-prefixed sequences, and primitives become YAML literals.
YAML is widely used for configuration files in tools like Docker Compose, Kubernetes, GitHub Actions, and Ansible. Its minimal punctuation makes it more readable than JSON for humans.
How to Use
  1. Paste the JSON you want to convert into the input field, or click Sample.
  2. Click → YAML to convert.
  3. Check the conversion result in the YAML output area.
  4. Click the Copy button to copy the result to clipboard.
Use Cases
Used for converting config for Docker Compose or Kubernetes manifests, generating environment-specific config files, converting sample data in API docs, and writing CI/CD pipeline configurations.
FAQ
  • How are strings with special characters handled? Strings containing special characters like colons, braces, or brackets are automatically quoted.
  • How is null converted? JSON's null is converted to the YAML null literal.
  • Can I convert back to JSON? Use a separate tool for YAML to JSON conversion. This tool supports one-way conversion from JSON to YAML only.
