FAQ
Which YAML version is supported?
YAML 1.2 via js-yaml, including anchors, multi-line strings, and most edge cases.
Are my files uploaded?
No. Conversion runs entirely in your browser.
Why does my JSON have keys in a different order after a round-trip?
Both JSON and YAML technically don't guarantee key order. js-yaml preserves insertion order on output, so you'll see your original ordering.
