• You show all but the important parts.. "I have added xlsx.full.min.js file." Show us how. + how do you import the library in the current file – Nico Van Belle Commented Apr 7, 2017 at 9:48

For typescript, you have to install @types/xlsx by npm install @types/xlsx --save.

Import it this way:

import * as XLSX from 'xlsx';

this is issue on their site.

You have to install the XLSX module using npm install xlsx then you have to intialize XLSX variable on top of your code if(typeof require !== 'undefined') XLSX = require('xlsx');. Check the library details: https://www.npmjs./package/xlsx
