Are nested objects turned into separate structs?

Yes, each nested object generates its own named struct based on the field name.

How are arrays typed?

Arrays become Go slices, e.g. []string or []int, based on their first element.

What if a field is null?

Null fields are typed as interface{} since no concrete type can be inferred.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
