# JSON to YAML

Convert JSON into readable YAML: quotes only where they are needed, block scalars for multi-line strings, and sequences written the way people write them.

## Questions

When does a value get quoted?+

Only when it would otherwise be read as something else: an empty string, one with leading or trailing space, one starting with a YAML indicator, or one that looks like a number, a boolean or null. Quoting everything is valid YAML and unreadable.

What happens to multi-line strings?+

They become a block scalar with |-, which keeps the line breaks visible instead of turning them into \\n inside a quoted string. That is the form that makes a script in a config file reviewable.

Is the conversion lossless?+

In this direction, yes: YAML is a superset of JSON, so every value has a form here. Going back the other way is where YAML features such as anchors and multiple documents have no JSON equivalent.
