ej

ej = export json to csv

原因

我们使用mongodb会经常导出json

mongoexport -d xbm-wechat-api -c senddeliveryhistories -o senddeliveryhistories.json  --jsonArray --query "{date:{\$in:['20150821','20150822']}}"

但json转成csv又没有上面的header，如果使用json2csv这样库，又无法解决对象嵌套的取值问题，所以就写了ej这个工具，它可以直接把mongoexport导出的json直接转成csv

比如

[
  {
    "__v": 0,
    "_id": {
      "$oid": "55bf208846b246fa238ff4d7"
    },
    "created_at": {
      "$date": "2015-08-03T08:04:24.648Z"
    },
    "date": "20150803",
  }
]

会生成以下4列

• __v
• _id.$oid
• created_at.$date
• date

Install

[sudo] npm install -g ej
