csv parser in node js

Reading data in from a csv can be handled in many ways. One solution is to read the csv file into an array. From there you can do work on the array.

Using FS to read in a CSV

fs is the File System API (opens new window) in node. We can use the method readFile on our fs variable, pass it a data.csv file, format and function that reads and splits the csv for further processing.

This assumes you have a file named data.csv in the same folder.

'use strict'

const fs = require('fs');

fs.readFile('data.csv', 'utf8', function (err, data) {
  var dataArray = data.split(/\r?\n/);
  console.log(dataArray);
});

You can now use the array like any other to do work on it.
