Question

how to convert json to csv or to store in sql

Answer 1

You can convert JSON data to csv in python using the pandas library - 

data = pandas.read_json()
data.to_csv()

If you wish to store data in SQL, perhaps it might be best to read the JSON data and first store it in a python data structure, like dictionary or a list, depending on which is more suitable. You may then write that data to SQL.
