Trying to parse only 3 key values from json file

[cubangt]

So here is what i have and seems to work, now im trying to save this to a CSV so i can test importing it into my excel report

import json
from datetime import datetime

f = open('messages.json')

data = json.load(f)

for message in data["messages"]:
    timestamp = datetime.fromtimestamp(message["timestamp_ms"] / 1000)
    
    if 'content' not in message:
        print(
            f"""{timestamp} from {message["sender_name"]}\n"""
        )
    else:
        print(
            f"""{timestamp} from {message["sender_name"]}\n{message["content"]}\n"""
        )

f.close()
