Node.js Tutorial to Parse & Read Contents of CSV File Using a-csv Library in Javascript

Welcome folks today in this blog post we will be parsing and reading contents of csv file using a-csv library in javascript. All the full source code of the application is shown below.

Get Started

In order to get started you need to make a new node.js project using the below command

npm init -y

npm i a-csv

After that you need to make a new index.js file and copy paste the following code

index.js

var CSV = require("a-csv");
var file = "users.csv";
var options = {
  delimiter: ",",
  charset: "win1250",
};

CSV.parse(file, options, function (err, row, next) {
  if (err) {
    return console.log(err);
  }

  if (row !== null) {
    console.log(row);
    return next();
  }

  console.log("finish");
});

var CSV = require("a-csv");

var file = "users.csv";

var options = {

delimiter: ",",

charset: "win1250",

};

CSV.parse(file, options, function (err, row, next) {

if (err) {

return console.log(err);

}

if (row !== null) {

console.log(row);

return next();

}

console.log("finish");

});

As you can see we are importing the library at the top and then we are loading the input csv file which is users.csv file and then we are providing the delimiter which is comma and then we are using the parse() method to provide the input file and then we are providing the options object and then we are also having the callback function in which we will be reading the contents of the file and showing it inside the command line.
