1. Schema input
Compilation fails closed on unsupported keywords.
Root object, primitive fields and one-dimensional primitive arrays. A successful schema edit reinitializes the instance from defaults. Clear the editor for the empty state.
2. Interactive form
Generated form
3. Instance inspection
Edit JSON here or use the form. Only valid instances export.
Exports sort object keys and preserve array order. Invalid JSON retains the previous form state. Invalid raw form input retains the last parsed field value and blocks export.
