node-campaign v0.0.2

Convert JSON documents to CSV

This node module will convert an array of JSON documents to a CSV string.

Column headings will be automatically generated based on the keys of the JSON documents. Nested documents will have a '.' appended between the keys.

Installation

$ npm install json-2-csv

Usage

var json2csv = require('json-2-csv');

json2csv Example:

var json2csv = 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, res) {
    if (err) throw err;
    console.log(res);
};

json2csv.json2csv(documents, json2csvCallback);

The above code prints out:

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

Features

• Header Generation (per document keys)
• Verifies all documents have same schema
• Supports sub-documents natively
• Custom ordering of columns (see F.A.Q. for more information)

F.A.Q.

• Can the order of the keys be changed in the output? Yes. Currently, changing the order of the keys in the JSON document will also change the order of the columns. (Node 10.26)
