How to export a HTML table to Excel supported by Chrome and IE?
Question
On my MVC project I have a HTML table bound with Knockout.
I'm trying to Export the table to Excel.
I tried on client side with JavaScript:
self.exportToExcel = function () {
javascript: window.open('data:application/vnd.ms-excel,' + $("#tableToprint").innerHTML());
}
OR:
var tableToExcel = (function () {
var uri = 'data:application/vnd.ms-excel;base64,'
, template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table cellspacing="0" rules="rows" border="1" style="color:Black;background-color:White;border-color:#CCCCCC;border-width:1px;border-style:None;width:100%;border-collapse:collapse;font-size:9pt;text-align:center;">{table}</table></body></html>'
, base64 = function (s) { return window.btoa(unescape(encodeURIComponent(s))) }
, format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }) }
return function (table, name) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
if (navigator.msSaveBlob) {
var blob = new Blob([format(template, ctx)], { type: 'application/vnd.ms-excel', endings: 'native' });
navigator.msSaveBlob(blob, 'export.xlsx')
} else {
window.location.href = uri + base64(format(template, ctx))
}
}
})()
But both codes work in Chrome but not in IE.
I would like to do it on client side using JavaScript or jQuery but if there is not a solution that is supported by both browsers I can also do it in server side with an AJAX Post Request to my Web API.
How can I export a HTML table to Excel supported by Chrome and IE using JavaScript/jQuery OR AJAX and Web API?
Any advice?

I use the eligrey.filesaver then just use it as
window.saveAs(blob,filename);
based on jparaya's answer I created a little sample in plunker , to save the file with filesaver It does the same as jparaya's code except for the saving part:
function fnExcelReport(id, name) {
var tab_text = '<html xmlns:x="urn:schemas-microsoft-com:office:excel">';
tab_text = tab_text + '<head><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet>';
tab_text = tab_text + '<x:Name>Test Sheet</x:Name>';
tab_text = tab_text + '<x:WorksheetOptions><x:Panes></x:Panes></x:WorksheetOptions></x:ExcelWorksheet>';
tab_text = tab_text + '</x:ExcelWorksheets></x:ExcelWorkbook></xml></head><body>';
tab_text = tab_text + "<table border='1px'>";
var exportTable = $('#' + id).clone();
exportTable.find('input').each(function (index, elem) { $(elem).remove(); });
tab_text = tab_text + exportTable.html();
tab_text = tab_text + '</table></body></html>';
var fileName = name + '_' + parseInt(Math.random() * 10000000000) + '.xls';
//Save the file
var blob = new Blob([tab_text], { type: "application/vnd.ms-excel;charset=utf-8" })
window.saveAs(blob, fileName);
}

Hmm I'm not really sure what's your problem. Looking at the code, seems everything is fine. Anyway, here I send you a simple implementation that I use, which can help you. Uses the same logic. Perhaps I check first IE version and that's why this works.
This sample has a simple link that executes the fnExcelReport function, passing table name and the excel name. I clone first, because my knockout code switches between view/edit modes with inputs. You can remove the clone and $(elem).remove() if you don't have that problem.
Edit: this version now implements the download for Chrome without the <a> tag in the html
function fnExcelReport(id, name) {
var tab_text = '<html xmlns:x="urn:schemas-microsoft-com:office:excel">';
tab_text = tab_text + '<head><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet>';
tab_text = tab_text + '<x:Name>Test Sheet</x:Name>';
tab_text = tab_text + '<x:WorksheetOptions><x:Panes></x:Panes></x:WorksheetOptions></x:ExcelWorksheet>';
tab_text = tab_text + '</x:ExcelWorksheets></x:ExcelWorkbook></xml></head><body>';
tab_text = tab_text + "<table border='1px'>";
var exportTable = $('#' + id).clone();
exportTable.find('input').each(function (index, elem) { $(elem).remove(); });
tab_text = tab_text + exportTable.html();
tab_text = tab_text + '</table></body></html>';
var data_type = 'data:application/vnd.ms-excel';
var ua = window.navigator.userAgent;
var msie = ua.indexOf("MSIE ");
var fileName = name + '_' + parseInt(Math.random() * 10000000000) + '.xls';
if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) {
if (window.navigator.msSaveBlob) {
var blob = new Blob([tab_text], {
type: "application/csv;charset=utf-8;"
});
navigator.msSaveBlob(blob, fileName);
}
} else {
var blob2 = new Blob([tab_text], {
type: "application/csv;charset=utf-8;"
});
var filename = fileName;
var elem = window.document.createElement('a');
elem.href = window.URL.createObjectURL(blob2);
elem.download = filename;
document.body.appendChild(elem);
elem.click();
document.body.removeChild(elem);
}
}
