Frequently Asked Questions

What JSON values become YAML booleans?

true and false in JSON map directly to true and false in YAML. Be aware that YAML 1.1 also treated 'yes', 'no', 'on', 'off' as booleans — quote string values like these in YAML to avoid confusion.

Can I convert a JSON array at the root level to YAML?

Yes. A root-level JSON array converts to a YAML sequence (list of items prefixed with dashes).
