Может быть, возможно, в т сделать CSV, используя этот сложный формат JSON для того, чтобы обрабатывать данные ровнее?

К примеру есть эта основная: -категория Основной информации фото создателем расположения категории URLs

Может быть, можно сделать файл CSV с категориями подкатегорий, как basic_information.id, creator.id и т.д. ?

возможно релевантно: http://stackoverflow.com/questions/16947643/getting-imported-json-data-into-a-data-frame-in-r – Paul

@Paul Спасибо. Я посмотрел на него. К сожалению, мой json более сложный. – Robbbbbi

Я опубликовал пару ссылок в комментариях, поскольку я изучал ваш ответ, но теперь я довольно убежден this is the way to do it.

Установите пакет узла, а затем использовать следующие с вашей собственной строки JSON, (который я только что поднял по ссылке выше.):

var converter = require('json-2-csv'); 

var documents = [ 
    { 
     Make: 'Nissan', 
     Model: 'Murano', 
     Year: '2013', 
     Specifications: { 
      Mileage: '7106', 
      Trim: 'S AWD' 
     } 
    }, 
    { 
     Make: 'BMW', 
     Model: 'X5', 
     Year: '2014', 
     Specifications: { 
      Mileage: '3287', 
      Trim: 'M' 
     } 
    } 
]; 

var json2csvCallback = function (err, csv) { 
    if (err) throw err; 
    console.log(csv); 
}; 

converter.json2csv(documents, json2csvCallback);

Это вернет:

Make,Model,Year,Specifications.Mileage,Specifications.Trim 
Nissan,Murano,2013,7106,S AWD 
BMW,X5,2014,3287,M

Спасибо, спасибо. Хороший ответ. Я запустил его. Можно ли загрузить json-файл и записать результаты после процесса в csv? – Robbbbbi

Вы имеете в виду записать его в файл и экспортировать? – Goodword

Да, я имею в виду, что у меня есть json-формат моего набора данных в json-файл. Я хочу загрузить его в dataframe, скажем, прочитать его. После этого сделайте процесс, который вы предлагаете, и напишите окончательные результаты в файл csv – Robbbbbi
