To use this library you need to have already the file uploaded, there are many libraries out there to select a file from your system. In the example below I provided an HTML(bootstrap) snippet and a JS snippet, of the components you need to have. Example

import xlsxParser from 'xlsx-parse-json';

xlsxParser
  .onFileSelection(file
  .then(data => {
    var parsedData = data;
  });

<html>
...
<form>
  <div class="form-group">
    <label for="exampleFormControlFile1">Example file input</label>
    <input type="file" class="form-control-file" id="exampleFormControlFile1">
  </div>
</form>
...
</html>

Example using AngularJS Install

npm install ng-file-upload
npm install xlsx-parse-json

index.js

'use strict';

var angular = require('angular');

require('ng-file-upload');

angular.module('test-xls-parser', ['ngFileUpload'])
.component('testXlsParserUpload', {
    template: '<input type="file" ngf-select="vm.uploadFile($file)" ng-disabled="vm.disableUpload" accept=".csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel"/><pre>{{vm.data | json}}</pre>',
    controller: function() {
        var vm = this;
        var xlsxParser = require('xlsx-parse-json');

        vm.uploadFile = function(file){
            xlsxParser.onFileSelection(file)
			.then((data) => {
				vm.data = data;
			});
        }
    },
    controllerAs: 'vm'
});
