Frequently asked questions

Is my JSON uploaded anywhere?

No. Conversion runs entirely in your browser (in a background worker for large files). Your data never leaves your machine.

How are strings handled?

Strings are quoted when they contain special characters, start/end with spaces, or are empty. Otherwise they are left unquoted for readability.

Does it preserve array order?

Yes. Arrays are always output in the order they appear in the JSON. Only object keys can be sorted (optionally).

What about null values?

Null is output as null in YAML, which is the standard representation.
