def remove_brackets(csv_file):
    with open(csv_file, 'r') as file:
        csv_reader = csv.reader(file)
        data = list(csv_reader)

    for i in range(len(data)):
        for j in range(len(data[i])):
            data[i][j] = data[i][j].replace('[', '').replace(']', '')

    with open(csv_file, 'w', newline='') as file:
        csv_writer = csv.writer(file)
        csv_writer.writerows(data)

remove_brackets('example.csv')
