我有一些非常大的json文件，我需要转换（最大的一个是500 MB）。在线工具仅支持小尺寸，不适合我。所以我看了stackoverflow来寻找可能对我有用的脚本。发现了这个：
import csv
import json
infile = open("test_user.json","r")
outfile = open ("test_user.csv","w")
writer = csv.writer(outfile)
for row in infile:
data = json.loads(row)
writer.writerow(data)
这是我的一个json文件的链接：https://pastebin.com/xpzeJmug
