How it works

Your schema is parsed with JSON.parse() and walked in the browser to build a deterministic example. Values come from const, examples, default and enum when present, then from types and formats. Local $ref and $defs / definitions pointers are resolved, and cyclic or external references are reported instead of looping. Nothing is uploaded.
