我有一个结构非常复杂的大JSON文件 您可以在这里查看： 它包含700多万行，我只想提取“text”字段 我已经编写了一个python代码，在整个文件中增加了“text”键或字段的所有值，它只提取了12个值！当我在Visualstudio上打开JSON文件时，我有超过19000个值 您可以在此处看到代码：Python 将数据从JSON文件提取到CSV,python,json,csv,machine-learning,deep-learning,Python,Json,Csv,Machine Learning,Deep Learning,我有一个结构非常复杂的大JSON文件 您可以在这里查看： 它包含700多万行，我只想提取“text”字段 我已经编写了一个python代码，在整个文件中增加了“text”键或字段的所有值，它只提取了12个值！当我在Visualstudio上打开JSON文件时，我有超过19000个值 您可以在此处看到代码： import json import csv with open("/Users/zahraa-maher/rasa-init-demo/venv/Tickie/external_d
