dir_json = './json'
data = {}
for directory, subdirs, files in os.walk(dir_json):
    for filename in files:
        filepath = os.path.join(directory, filename)
        f = open(filepath, 'r')
        data.update(json.load(f))
        f.close()

f = csv.writer(open('file.csv', 'w'))
for key, val in data.items():
