How to use the JSON to YAML Converter

  1. Paste your JSON into the left box, or open a file.
  2. Adjust the options if you need to.
  3. Copy the YAML or download it as a file.

What does this tool do?

YAML is the configuration format behind Kubernetes, Docker Compose, GitHub Actions and many CI tools, but API docs and examples are usually written in JSON. This converter turns JSON into equivalent YAML with two-space indentation.

Strings are only quoted when needed, so the YAML stays readable, and long lines aren't wrapped, which keeps values intact. Check the result with the YAML to JSON converter to confirm it round-trips.

Why use it?

  • Write configuration files faster.
  • Convert API examples into YAML configs.
  • Readable output with sensible quoting.

Example

{"server":{"port":8080}} becomes:
server:
  port: 8080
