To add any json file, use the data_type as json. Headers are included for each line, so for example if you have a json like {"age": 18}, then it will be added as age: 18.

Here are the supported sources for loading json:

1. URL - valid url to json file that ends with ".json" extension.
2. Local file - valid url to local json file that ends with ".json" extension.
3. String - valid json string (e.g. - app.add('{"foo": "bar"}'))

If you would like to add other data structures (e.g. list, dict etc.), convert it to a valid json first using json.dumps() function.
