Angular 14 ngx-csv Example to Export JSON Data to CSV File & Download it inside Browser Using TypeScript

Welcome folks today in this blog post we will be using the ngx-csv library to export json to csv file and download it inside the browser using typescript in browser. All the full source code of the application is shown below.

Get Started

In order to get started you need to make a new angular project using the below command as shown below

ng new sampleproject

cd sampleproject

And after that you need to install the below libraries using the below command as shown below

npm i ngx-csv

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

And now we need to go to app.component.html file and copy paste the following code

app.component.html

<ul *ngFor="let d of data">
    <li>{{d.name}}</li>
    <li>{{d.age}}</li>
    <li>{{d.country}}</li>
</ul>
<button (click)="downloadCSV()">Download CSV</button>

<li>{{d.country}}</li>

</ul>

<button (click)="downloadCSV()">Download CSV</button>

As you can see in the above html code we are displaying the json array of objects inside the ul tag and here we are using the ngFor directive to use the for loop to display the name age and country. And then we have the button to export the json to csv file using the ngx-csv library as shown below.

And now we need to go to app.component.ts file and copy paste the below code

app.component.ts

import { Component } from '@angular/core';
import { ngxCsv } from 'ngx-csv/ngx-csv';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
})
export class AppComponent {
  title="export to csv"

   data = [
    {
      name:'John Williamson',
      age:25,
      country:'New Zealand'
    },
    {
      name:'Trent Boult',
      age:27,
      country:'New Zealand'
    },
    {
      name:'Devon Conway',
      age:32,
      country:'New Zealand'
    },
    {
      name:'Tim Southee',
      age:29,
      country:'New Zealand'
    }
  ];

  downloadCSV() {
    
    var options = {
      title: 'User Details',
      fieldSeparator: ',',
      quoteStrings: '"',
      decimalseparator: '.',
      showLabels: false,
      noDownload: false,
      showTitle: false,
      useBom: false,
      headers:['Name','Age','Country']
    };

     new ngxCsv(this.data, "report", options);

  }
}

import { Component } from '@angular/core';

import { ngxCsv } from 'ngx-csv/ngx-csv';

@Component({

selector: 'app-root',

templateUrl: './app.component.html',

styleUrls: ['./app.component.css'],

})

export class AppComponent {

title="export to csv"

data = [

{

name:'John Williamson',

age:25,

country:'New Zealand'

{

name:'Trent Boult',

age:27,

country:'New Zealand'

{

name:'Devon Conway',

age:32,

country:'New Zealand'

{

name:'Tim Southee',

age:29,

country:'New Zealand'

}

];

downloadCSV() {

var options = {

title: 'User Details',

fieldSeparator: ',',

quoteStrings: '"',

decimalseparator: '.',

showLabels: false,

noDownload: false,

showTitle: false,

useBom: false,

headers:['Name','Age','Country']

};

new ngxCsv(this.data, "report", options);

}

As you can see in the above typescript code we are importing the ngx-csv module at the top and then we are declaring the json object in which we are storing the user details. And inside the downloadCSV() method we are declaring the options where we are providing the headers of the csv file and then we are using the ngxCsv() constructor to pass the json data and then we are providing the name of the csv file and we are providing the options.
