确定大 json 文件的架构

问题描述

我正在使用 MongoDB Atlas，在查看集合时可以看到所有查询结果，但并非所有查询结果都包含相同的字段。集合保存为 json 文件，以新行分隔。包含不同字段的两行示例：

{"_id": "6076da4d4c","settings": {"notifications": {"hour": 17,"minute": 0,"enabled": true,"days": [1,2,3,4,5]},"numberOfQuestions": 2},"score": 0,"completedRegistration": true,"firstname": "Name","lastname": "Surname","username": "usrnm","email": "[e-mail]","password": "$2b$10$yr4R0yZJC","createdAt": "2021-04-14T12:06:16.376Z","updatedAt": "2021-04-14T12:07:39.376Z","__v": 0,"dailyQuestions": {"5fa3bc": {"d1": {"timestamp": "2021-04-14T12:06:35.834Z","examples2": []},"d2": {"examples2": []}}},"tPoints": {}}

和

{"_id": "5b869b","email": "[e-mail]","username": "user","name": "something something","password": "$2b$.","first_part": [],"examples": [],"counterexamples": [],"company": "5ae9","isAdmin": false,"settings": {"numberOfQuestions": 2},"scores": {},"updatedAt": "2021-01-29T13:31:58.984Z"}

文件非常大，很难在 BigQuery 中手动输入模式（在 BigQuery 中自动输入会引发错误，因为“找不到活动字段”）。有用于此的在线 json 工具，但这意味着对每一行都执行此操作。

还有什么办法吗？
