Node.js Project to Convert JSON Objects to CSV File Using json2csv Library in Javascript

Welcome folks today in this blog post we will be converting json objects to csv file using json2csv 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 as shown below

npm init -y

npm i json2csv

And after that you will see the below directory structure of the app is shown below

Basic Example

Now we will be seeing the basic example to convert the array of json objects to csv file

index.js

const json2csv = require('json2csv').parse;
const fs = require('fs');

// Example JSON data
const data = [
  { name: 'John Doe', email: 'johndoe@example.com', age: 30 },
  { name: 'Jane Smith', email: 'janesmith@example.com', age: 25 },
  { name: 'Bob Johnson', email: 'bobjohnson@example.com', age: 40 }
];

// Define fields to include in CSV
const fields = ['name', 'email', 'age'];

// Convert JSON to CSV
const csv = json2csv(data, { fields });

// Write CSV to file
fs.writeFile('data.csv', csv, function(err) {
  if (err) throw err;
  console.log('CSV file saved!');
});

const json2csv = require('json2csv').parse;

const fs = require('fs');

// Example JSON data

const data = [

{ name: 'John Doe', email: 'johndoe@example.com', age: 30 },

{ name: 'Jane Smith', email: 'janesmith@example.com', age: 25 },

{ name: 'Bob Johnson', email: 'bobjohnson@example.com', age: 40 }

];

// Define fields to include in CSV

const fields = ['name', 'email', 'age'];

// Convert JSON to CSV

const csv = json2csv(data, { fields });

// Write CSV to file

fs.writeFile('data.csv', csv, function(err) {

if (err) throw err;

console.log('CSV file saved!');

});

As you can see that in the above code we are importing the json2csv library and then we are having the array of json objects and then we are using the json2csv() method to export it to csv file.
