        <tr>
            <td style="width:9.2%"><b>Load CSV file</b></td>
            <td style="width:1%"><b>:</b></td> 
            <td style="width:15%"><input type="file" id="fileInputCSV" /></td>
        </tr>
    </table>
 <table id="result"></table>

        <script type="text/javascript">

            // check browser support
            // console.log(SimpleExcel.isSupportedBrowser);

            var fileInputCSV = document.getElementById('fileInputCSV'); 


            // when local file loaded
            fileInputCSV.addEventListener('change', function (e) {

                // parse as CSV
                var file = e.target.files[0];
                var csvParser = new SimpleExcel.Parser.CSV();
                csvParser.setDelimiter(',');
                csvParser.loadFile(file, function () {

                    // draw HTML table based on sheet data
                    var sheet = csvParser.getSheet();
                    var table = document.getElementById('result');
                    table.ierHTML = "";
                    sheet.forEach(function (el, i) {                    
                        var row = document.createElement('tr');
                        el.forEach(function (el, i) {
                            var cell = document.createElement('td');
                            cell.ierHTML = el.value;
                            row.appendChild(cell);
                        });
                        table.appendChild(row);
                    });
