  }

我正在尝试将其自动转换为CSV格式。通常这将是一个非常简单的json2csv脚本，但由于某种原因，这次我遇到了一个问题，我正在努力解决问题。我的文件正在创建，但只包含标题而没有数据。

我在https://github.com/zemirco/json2csv上阅读了文档，我想我会在字段中使用点符号，但由于它的设置方式，我不确定点之前会有什么？

我尝试了CLI版本和实际的JS版本但同样的交易。我得到的只是标题。正如您将在脚本中看到的那样，我只关心JSON文档的各个部分，但即使我尝试全部完成，我仍然只能获得标题。我以前的版本都使用了glob，但是直接指向文件的CLI仍会得到相同的结果。

var json2csv = require('json2csv');
var fs = require('fs');
var glob = require('glob');

let fields = 
    [
        "subscriberid",
        "Title",
        "FirstName",
        "LastName",
        "EmailAddress",
        "Mobile",
        "Postcode",
        "Gender",
        "SubscribeDate",
        "Birthday",
        "Kids",
        "Kidsages",
        "Student",
        "Favourite",
        "attendreason",
        "MarketingOptIn",
        "Source"
    ];

let dataInput = glob("path/**/toFile.txt");

var csv = json2csv({ data: dataInput, fields: fields });

fs.writeFile('output.csv', csv, function(err) {
  if (err) throw err;
  console.log('file saved');
});

JSON2CSV没有输出值
