Como usar

Generate Go structs

Paste a representative JSON object and run Convert. Field types are inferred from the sample values.

  1. Paste a JSON object.
  2. Click Convert.
  3. Copy the generated Go code.

Type inference

Whole numbers become int, decimals become float64, booleans become bool, strings become string and nested objects become named structs.

Perguntas frequentes

Why is a null field typed as interface{}?

A null value gives no type information, so the generator falls back to interface{}.

Does it handle arrays of objects?

Yes. Arrays become slices, and arrays of objects produce a nested struct type.
