About the JSON to YAML Converter

YAML is easier to read and edit by hand, which is why so many configuration systems use it. Paste JSON and get equivalent YAML with your chosen indentation; strings that need quoting (like “yes”, “on” or values with colons) are quoted automatically to avoid type surprises.

How to use it

  1. Paste JSON or open a file.
  2. Choose 2 or 4 spaces.
  3. Copy or download the YAML.

Good to know

  • Key order is preserved.
  • Comments cannot be generated because JSON has none.

Frequently asked questions

Is all JSON valid YAML?

YAML 1.2 is a superset of JSON, so yes — but converted YAML is much more readable.

Why are some strings quoted?

Unquoted values like yes or 1e3 could be read as booleans or numbers.
