How to generate a Swagger #definition from sample JSON

Question

Take the following #definition from the pet store example. Given a #definition section a JSON structure can be generated

e.g.

Is there something that can do the reverse given a largeish complex JSON file?

Given the below JSON Structure can I get the #defintion section of a swagger file generated to save some typing

{   "variable": "sample",   "object1": {     "obj-field1": "field 1 of object",     "obj-field2": "field 2 of object",     "anArray": [       "Value 1",       {         "anArrayObj1": "obj1fieldinarray",         "anArrayObj2": "obj2fieldinarray"       }     ]   } }

You can use this JSON-to-OpenAPI schema converter:

(GitHub project)

I haven't used it personally though, so I'm not sure how good it is.

Since OpenAPI uses a subset of JSON Schema, you could also use one of the JSON Schema generators, however you may need to manually tweak the generated definition to make it OpenAPI-compatible.
