    Assume my Biguery table has of JSON type.

    I am trying to insert a dictionary to my table using python bq client. I am able to insert the data using different functions like load_table_from_json. I have specified column as JSON type in job config schema of the big query table.

    My dictionary in python - {"A": 2, "B": 1, "C": 4, "D": 3}

    The result in table -

    "

    {\n\"A\":2,\n\"B\":1,\n\"C\":4,\n\"D\":3\n}"


    I don't want the delimiters to appear. I get why they are appearing as bigquery converts the dictionary to a type it can understand resulting the the above structure when entering into the table.

    I Have a manual workaround if i directly write the insert command and use the bq_client.query() function. I can make user of parse_json function , this helps in getting the desired result of {"A": 2, "B": 1, "C": 4, "D": 3}.

    But I couldn't find any python BQ library way of achieving the same. Is there a way to do this?
