Source Code        DEMO

Program Flow

  1. Get CSV file content using HTTP request
  2. Process CSV file data
  3. Format JavaScript object and display it in a table

Markup to display CSV content in Table

The below markup shows csvData in table view
<table border="1" class="demoTable">
   <tr *ngFor="let x of csvData">
      <td *ngFor="let y of x">{{ y }}</td>

Script - app.component.ts

import { Http, Response } from '@angular/http';

  selector: 'my-app',
  template: `
  <h2>CSV Data</h2>
    <button class="btn btn1 btn2" (click)="readCsvData()">
       Read CSV Data
    <table border="1" class="demoTable">
      <tr *ngFor="let x of csvData">
        <td *ngFor="let y of x">{{ y }}</td>
export class AppComponent {
  csvUrl: string = 'sample.csv';  // URL to web API
  csvData: any[] = [];

  constructor (private http: Http) {}

  readCsvData () {
      data => this.extractData(data),
      err => this.handleError(err)

  private extractData(res: Response) {

    let csvData = res['_body'] || '';
    let allTextLines = csvData.split(/\r\n|\n/);
    let headers = allTextLines[0].split(',');
    let lines = [];

    for ( let i = 0; i < allTextLines.length; i++) {
        // split content based on comma
        let data = allTextLines[i].split(',');
        if (data.length == headers.length) {
            let tarr = [];
            for ( let j = 0; j < headers.length; j++) {
    this.csvData = lines;

  private handleError (error: any) {
    // In a real world app, we might use a remote logging infrastructure
    // We'd also dig deeper into the error to get a better message
    let errMsg = (error.message) ? error.message :
      error.status ? `${error.status} - ${error.statusText}` : 'Server error';
    console.error(errMsg); // log to console instead
    return errMsg;
