xls-parser #

$3

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;
});

``

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: '

{{vm.data | json}}

',
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
