Generating TypeScript interfaces

Paste a JSON sample and press Convert to obtain interfaces. Union types are produced for mixed arrays.

  1. Paste a JSON sample.
  2. Press Convert.
  3. Copy the interfaces into your project.

Questions fréquentes

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[].
