Generate sample Json output from Json Schema

Question

I want to know whether there is a method in which I can generate sample json output based on a json schema input.

for example :-

input =>

{
"title": "Example Schema",
"type": "object",
"properties": {
    "firstName": {
        "type": "string"
    },
    "lastName": {
        "type": "string"
    },
    "age": {
        "description": "Age in years",
        "type": "integer",
        "minimum": 0
    }
},
"required": ["firstName", "lastName"]
}

output => 

{     
  "firstName" : "RandomFirstName",
   "lastName" : "RandomLastName"
}

I have a large Json Schema with plenty of validations so to generate a sample valid json I could either create one manually using either Java or just a type it into a file. Is there a better way available ?

Answer 1

You can try the JSON Schema Faker. It will take a schema and generate/output a JSON object that will validate against the schema.

Answer 2

JSONBuddy can do this for you. It is a Windows desktop JSON editor and generates live JSON sample data while you are editing your schema.
