ValueError：所有 arrays 的長度必須相同

Question

有人可以幫助解決將 json 文件轉換為數據框的錯誤嗎？

我正在嘗試將 JSON 文本文件轉換為數據框，但得到數組相同長度錯誤。 我已經在“數據”周圍嘗試了雙 [[]]，但仍然無法正常工作。 The text file is at https://stackoverflowtez.filecloudonline.com/ui/core/index.html?mode=single&path=/SHARED/%212CkRNC5x55IO6kGJjEwTViZ4mGmwG/9aINFGD2QxaELHFL&shareto=#expl-tabl .

df_matchDetails = pd.DataFrame(responsematchDetails.json()['data'])

ValueError: All arrays must be of the same length

JSON 的一部分貼在下面，整個 output 在鏈接的 convert.txt 中

問題來自 JSON 文件的嵌套部分。 您可以使用 Pandas 中的json_normalize() function 來解決您的問題：

import pandas as pd
import json

with open("convert.txt",'r') as f:
    data = json.loads(f.read())
df = pd.json_normalize(data, record_path =['data'])
