可以在r中使用这种复杂的json格式制作一个csv,以便更平滑地处理数据吗?

例如,有以下基本类别:基本信息照片创建者位置类别网址

可以制作带有basic_information.id,creator.id等子类别类别的csv文件吗?

在研究您的答案时,我在评论中张贴了一些链接,但现在我非常确信这是解决问题的方法

安装节点包,然后将以下内容与您自己的json字符串结合使用(我刚刚从上面的链接中删除了该字符串):

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);

这将返回:

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