Tool to generate JSON schema from JSON data [close

Question

We have this json schema draft. I would like to get a sample of my JSON data and generate a skeleton for the JSON schema, that I can rework manually, adding things like description, required, etc, which can not be infered from the specific examples.

For example, from my input example.json:

{
    "foo": "lorem", 
    "bar": "ipsum"
}

I would run my json_schema_generator tool and would get:

{ "foo": {
    "type" : "string",
    "required" : true,
    "description" : "unknown"
  },
  "bar": {
    "type" : "string",
    "required" : true,
    "description" : "unknown"
  }
}

This example has been coded manually, so it has maybe errors. Is there any tool out there which could help me with the conversion JSON -> JSON schema?

Answer 1

There are a lot of tools mentioned, but one more called JSON Schema inferencer for the record:

https://github.com/rnd0101/json_schema_inferencer

(it's not a library or a product, but a Python script)
