What this tool does
This JSON Schema tool generates representative sample data from your schema, entirely in your browser. It runs entirely in your browser — your data never leaves the page.
How it works

2. Choose enum, const, format, and type examples.
3. Build nested objects and arrays.
4. Return formatted sample JSON.
