JSON to YAML Converter

YAML holds the same data as JSON but is easier for people to read and edit, which is why Kubernetes, Docker Compose, GitHub Actions and many apps use it for configuration. Paste JSON and get equivalent YAML, with strings quoted only where YAML needs it. The conversion uses the well-tested js-yaml library and runs in your browser.

How to use JSON to YAML Converter

2. Choose 2 or 4 spaces of indentation and, if you like, sort keys alphabetically.

Frequently asked questions

Is YAML a superset of JSON?

Yes, YAML 1.2 accepts JSON as valid YAML, but the indented YAML style is much easier to read.

Why are some strings quoted?

Values such as "yes", "no", "on", "1.0" or strings starting with special characters would be read as booleans, numbers or syntax, so they are quoted to keep them as text.
