Hi,

If you are looking to read a csv file you can try the following code

csv_data = base64.b64decode('your binary field')
data_file = io.StringIO(csv_data.decode("utf-8"))
data_file.seek(0)
file_reader = []
csv_reader = csv.reader(data_file, delimiter=',')
file_reader.extend(csv_reader)

in the above code the data will be in file_reader

Regards
