I'm having trouble going through the data because of the ID 29450 and 3000 in this JSON data sample. My whole database has 1500 ID's. Now I want to print the data `['Id', 'Description', 'StartDate']` in the log from both ID's.

I'm a bit stuck now so hopefully somebody can help on the right track.

Thank you in advance. :)

```
const { Parser } = require('json2csv');
var fs = require('fs');

var fields = ['Id', 'Description', 'StartDate'];

var data = [
  {
    "29450": {
        "Id": "29450",
        "Description": "Lasser Niveau 4",
        "StartDate": "0001-01-01T00:00:00",
        "EndDate": "0001-01-01T00:00:00",
        "Company": "",
        "ResponsibilityCenter": "",
        "FunctionGroup": "",
        "City": "",
        "Territory": "",
        "Country": "",
        "Attributes": {
            "Name": {
                "Description": "",
                "Name": ""           
            },
            "WERKTIJDEN": {
                "Description": "Anders",
                "Name": "Werktijden"
            }
        },
        "RequestNo": ""
    },
    "3000": {
        "Id": "3000",
        "Description": "Lasser Niveau 4",
        "StartDate": "0001-01-01T00:00:00",
        "EndDate": "0001-01-01T00:00:00",
        "Company": "",
        "ResponsibilityCenter": "",
        "FunctionGroup": "",
        "City": "",
        "Territory": "",
        "Country": "",
        "Attributes": {
            "Name": {
                "Description": "",
                "Name": ""                      
            },
            "WERKTIJDEN": {
                "Description": "Anders",
                "Name": "Werktijden"
            }
        },
        "RequestNo": ""
    },
];

const json2csvParser = new Parser({fields, unwind: ['Id','Description','StartDate'], unwindBlank: true });
const csv = json2csvParser.parse(data);    
fs.writeFile('file.csv', csv, function(err) {
    if (err) throw err;
    console.log('file saved');
  });

```

Expected output:
