Also, you can pass an array of objects to be serialized, in which case the object's properties will be iterated over. E.g.:

    res.csv([
        {
            SN: 000001,
            Major:0001,
            Minor: 0001
        },{
            SN: 000002,
            Major:0002,
            Minor: 0002 
        }
    ])
//=> 000001, 0001, 0001
//=> 000002, 0002, 0002
