Export HTML table to Excel file

Question

I\'ve been looking into some jQuery plugins that are capable of doing this. I decided to use the one at http://www.jqueryscript.net/table/Export-Html-Table-To-Excel-Spreads

Here is the best way you can do. You can specify the file name too for downloading. Just pass tableid, sheet name, file name to the function below, it will download. See fiddle for downloading in IE too.

https://jsfiddle.net/ndncll/ehnbxo1u/

function tableToExcel(table, sheetName, fileName) {
fileName = fileName + new Date().formatDateTime('MM_DD_YYYY', 'HH_mm_ss');

var uri = 'data:application/vnd.ms-excel;base64,',
    templateData = '{table}',
    base64Conversion = function (s) { return window.btoa(unescape(encodeURIComponent(s))) },
    formatExcelData = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }

$("tbody > tr[data-level='0']").show();

if (!table.nodeType)
    table = document.getElementById(table)

var ctx = { worksheet: sheetName || 'Worksheet', table: table.innerHTML }

var element = document.createElement('a');
element.setAttribute('href', 'data:application/vnd.ms-excel;base64,' + base64Conversion(formatExcelData(templateData, ctx)));
element.setAttribute('download', fileName);
element.style.display = 'none';
document.body.appendChild(element);
element.click();
document.body.removeChild(element);}
