JSON 到特定格式的 CSV

Question

我正在尝试将 Json 文件转换为 Csv

我无法构建逻辑。这是我试过的

代码

import json
import csv
import os

with open('truck_trips.json') as json_file:
    data = json.load(json_file)

file_path = 'json_data.csv'
    
if not os.path.exists(file_path):
    print("No File")
    header = ['Truck_Id', 'Trip_Id', 'Start', 'End']
    with open(file_path, 'w') as f:
        writer = csv.writer(f)
        writer.writerow(header)
    
    for item in data:
        print(item)
        for t in data[item]:
            print(t)
            print(data[item][t])
        print("\n")

Answer 1

这样就可以了，

# Getting the JSON content.
with open("/content/truck_trips.json", "r") as f:
  json_output = f.read()

output_dict = json.loads(json_output)

# Storing the relevant data from the JSON file into a list.
trucks_detail = []

for truck in output_dict:
  for trip in output_dict[truck]:
    trips = output_dict[truck][trip]

    for i in range(len(trips)):
      start, end = trips[i][0], trips[i][1]
      truck_detail = [truck, f"{trip}.{i + 1}", start, end]
      trucks_detail.append(truck_detail)

# Converting it into a dataframe.
df = pd.DataFrame(trucks_detail, columns = ["Truck_Id", "Trip_Id", "Start", "End"])
df.to_csv("Truck Details.csv", index = False)

数据框，

	Truck_Id	Trip_Id	Start	End
0	truck_1	trip_1.1	Toronto	Kitchener
1	truck_1	trip_1.2	Kitchener	Cobourg
2	truck_1	trip_1.3	Cobourg	Aylmer
3	truck_1	trip_1.4	Aylmer	Owen Sound
4	truck_1	trip_1.5	Owen Sound	Orillia
5	truck_1	trip_1.6	Orillia	Toronto
6	truck_1	trip_2.1	Toronto	Ottawa - Gatineau
7	truck_1	trip_2.2	Ottawa - Gatineau	Welland - Pelham
8	truck_1	trip_2.3	Welland - Pelham	Toronto
9	truck_1	trip_3.1	Toronto	Fort Frances
