How to generate types from JSON

  1. Choose TypeScript, Go or JSON Schema.
  2. Paste an example of your JSON, or try the example.
  3. Adjust the options, then copy or download the code.

How the types are worked out

  • Every object gets its own named type; items of arrays get a singular name ("users" becomes User).
  • All items of an array are looked at together: a field missing from some items becomes optional.
  • Numbers become number in TypeScript, and int64 or float64 in Go depending on the values.
  • Mixed values become a union in TypeScript, any in Go and a list of types in JSON Schema.
  • JSON Schema can also detect formats such as date-time, email, uri and uuid.

Check the result

The types describe your example, not every possible response. A field that was null or missing in the example can't tell what type it really has, so check those by hand.
