Answer 1

You can't append JSON files together into a new JSON, because of the nature of the JSON format.

Instead of writing each object individually to the JSON file, you should collect all of the objects into a list, and write the list to the JSON file:

lst = []
for data in ...:
    lst.append(data)

with open("data.json", "w", encoding='utf-8') as f:
    #                   ^ notice "a" was changed to "w" here
    json.dump(lst, f, ensure_ascii=False, indent=4)

Answer 2

Both can be done with pandas

• To store json data in a.json file, use pandas.DataFrame.to_json

• To save json data in a.csv file, first use pandas.read_json to read the data into a dataframe and then use pandas.DataFrame.to_csv
