• Valid JSON sample

  The converter starts only after the pasted JSON parses successfully.

• Primitive inference

  String, number, boolean, null, array, and object values are mapped to TypeScript.

• Nested objects

  Nested structures are emitted inline so the generated type matches the sample shape.

• Array unions

  Arrays with mixed item shapes produce a union of inferred item types.

• Sample limitation

  Only the pasted sample is inferred; absent fields and alternate API responses cannot be guessed.
