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.

​
Example

from embedchain import App

app = App()

# Add json file
app.add("temp.json")

app.query("What is the net worth of Elon Musk as of October 2023?")
# As of October 2023, Elon Musk's net worth is $255.2 billion.
