    I hope I can explain this well.

    I’m making a small Angular project to take data from multiple CSV files and then display it in a tabulated page with tables. The part I’m having issues with is getting the data from CSV to Array.

    Can anyone help me with just that part. I’ve seen a bunch of posts online about using javascript/jquery to read the CSV into an array but can’t get any of them to work.

    I was hoping to write a simple function that I can include in inline js to parse the different files on page load and then send that data into my Angular array to be used.

    <script src=""></script>
    <script src="" integrity="sha384-0mSbJDEHialfmuBBQP6A4Qrprq5OVfW37PRR3j5ELqxss1yVqOtnepnHVP9aJ7xS" crossorigin="anonymous"></script>
    <script src=""></script>
    <script src=""></script>
    <script type="text/javascript">

    So I’ve managed to work out a small solution but my issue is now that I can’t iterate through my data in the array for Angular.

    <script type="text/javascript">
                var purchasingApp = angular.module('purchasingApp', []);
                purchasingApp.controller('ReportListCtrl', function($scope){

                            'name': 'September',
                            'data': getCSV('data.csv').done(function(data){ CSV2JSON(data); })
