Does this handle nested objects and arrays?
Yes. Nested JSON objects and arrays are converted into properly indented YAML block structure, however deeply they're nested.

What if my JSON is invalid?
The converter shows an error message describing what's wrong with your JSON (like a missing comma or bracket) instead of producing broken output.
Is my JSON uploaded anywhere?
No. Conversion runs entirely in your browser. Nothing is sent to TripleW Tools or any other server.
