Readme
Parse csv, xls, xlsx into json. Having multiple sheets is not an issue we return and object for each sheet found. See example below for more info. Visit https://abelalvarez.info/xls-parser/ to test it online.
npm install xls-parser
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 'xls-parser';
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 xls-parser
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 xlsParser = require('xls-parser');
vm.uploadFile = function(file){
xlsParser.onFileSelection(file)
.then((data) => {
vm.data = data;
});
}
},
controllerAs: 'vm'
});

There are optional parameters to show. They should be provided in the second argument
The default values are { showNullProperties = false, hideEmptyRows = true }
onFileSelection = (file, { showNullProperties = false, hideEmptyRows = true })
Setting showNullProperties = true; will show all properties on every object example
