I am trying to convert JSON data into a CSV in Python and found this code listed on Stack Exchange from a while back (link: How can I convert JSON to CSV? )
It no longer works in Python 3, giving me different errors. Anyone know how to fix for Python 3? Thanks.
import csv
import json
x = """[
{
"pk": 22,
"model": "auth.permission",
"fields": {
"codename": "add_logentry",
"name": "Can add log entry",
"content_type": 8
}
},
{
"pk": 23,
"model": "auth.permission",
"fields": {
"codename": "change_logentry",
"name": "Can change log entry",
"content_type": 8
}
},
{
"pk": 24,
"model": "auth.permission",
"fields": {
"codename": "delete_logentry",
"name": "Can delete log entry",
"content_type": 8
}
}
]"""
x = json.loads(x)
f = csv.writer(open("test.csv", "wb+"))
# Write CSV Header, If you dont need that, remove this line
f.writerow(["pk", "model", "codename", "name", "content_type"])
for x in x:
f.writerow([x["pk"],
x["model"],
x["fields"]["codename"],
x["fields"]["name"],
x["fields"]["content_type"]])
您正在使用wb+
将文件打开为二进制文件,而您正在尝试写str
。
f = csv.writer(open("test.csv", "w+"))
Maybe this code will help you in some way to understand that.
import json,csv
data = []
with open('your_json_file_here.json') as file:
for line in file:
data.append(json.loads(line)) length = len(data)
with open('create_new_file.csv','w') as f:
writer = csv.writer(f)
writers = csv.DictWriter(f, fieldnames=['header1','header2'])
writers.writeheader()
for iter in range(length):
writer.writerow((data[iter]['specific_col_name1'],data[iter]['specific_col_name2'])) f.close()
