  2. Press Convert.
  3. Copy the interfaces into your project.

Perguntas frequentes

Are fields marked optional?

Fields missing from the sample are not inferred, so optionality is only added when a value is null.

How are arrays typed?

Homogeneous arrays use a single type, mixed arrays produce a union type and empty arrays produce unknown[].
