我有一个如下所示的JSON文件：

我不确定如何正确解析它。似乎它可以将大多数行解析为CSV，但仍将括号括在
"Posrtofdischarge"行，并在"incoterms"行中再次对其进行解析。
每当有新的“ {}”时，问题就不断在JSON中返回。
可能是什么原因？
我使用的代码是：
import json
import os
from glob import glob
import csv
def JSONParse():
'''
curdir = input("Please enter your json dir")
os.chdir(curdir)
'''
os.chdir('C:\OutputJSON')
global data
data = []
global collist
collist = []
for file_name in glob('*.json'):
with open(file_name) as f:
data = json.loads("[" + f.read().replace("}\n{", "},\n{") + "]") #json creation for each file
def ColParse():
for da in data:
for key in da.keys():
if key not in collist:
collist.append(key.split(":")[0])
collist.append("CustomerID") # appending file name and ip from so it can be added to the csv.
collist.append("Timestamp")
print(collist)
def CSVWrite():
count = 0
with open("postgres.csv", 'a') as c:
thewriter = csv.DictWriter(c, fieldnames=collist)
if count == 0:
thewriter.writeheader()
thewriter.writerows(data)
count = 1
def main():
JSONParse()
ColParse()
CSVWrite()
if __name__ == "__main__":
main()
