FAQs
What YAML does it support?
Basic YAML: key-value mappings, lists, nested structures, quoted strings, numbers, booleans and null, using spaces for indentation.
Does it support anchors or multi-line strings?
Not yet. Advanced features like anchors, aliases and block scalars are skipped; keep to plain mappings and lists.
Why did a value become a string?
Unquoted values that are not numbers, true, false or null are treated as strings, which matches YAML rules.
Is my data sent anywhere?
No. Conversion happens entirely in your browser.
