Export html table data to Excel using JavaScript / JQuery is not working properly in chrome browser


I have a HTML table in velocity template. I want to export the html table data to excel using either java script or jquery, comatibale with all browser. I am using below script

<script type="text/javascript">
function ExportToExcel(mytblId){
       var htmltable= document.getElementById('my-table-id');
       var html = htmltable.outerHTML;
       window.open('data:application/vnd.ms-excel,' + encodeURIComponent(html));
    }
</script>

This script works fine in Mozilla Firefox,it pops-up with a dialog box of excel and ask for open or save options. But when I tested same script in Chrome browser it is not working as expected,when clicked on button there is no pop-up for excel. Data gets downloaded in a file with "file type : file" , no extension like .xls There are no errors in chrome console.

Jsfiddle example :

This works fine in mozilla but not in chrome.

Chrome browser Test Case :

First Image:I click on Export to excel button

First Image:I click on Export to excel button

and result :

Result

Excel export script works on IE7+, Firefox and Chrome.

function fnExcelReport()
{
    var tab_text="<table border='2px'><tr bgcolor='#87AFC6'>";
    var textRange; var j=0;
    tab = document.getElementById('headerTable'); // id of table

    for(j = 0 ; j < tab.rows.length ; j++) 
    {     
        tab_text=tab_text+tab.rows[j].innerHTML+"</tr>";
        //tab_text=tab_text+"</tr>";
    }

    tab_text=tab_text+"</table>";
    tab_text= tab_text.replace(/<A[^>]*>|<\/A>/g, "");//remove if u want links in your table
    tab_text= tab_text.replace(/<img[^>]*>/gi,""); // remove if u want images in your table
    tab_text= tab_text.replace(/<input[^>]*>|<\/input>/gi, ""); // reomves input params

    var ua = window.navigator.userAgent;
    var msie = ua.indexOf("MSIE "); 

    if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))      // If Internet Explorer
    {
        txtArea1.document.open("txt/html","replace");
        txtArea1.document.write(tab_text);
        txtArea1.document.close();
        txtArea1.focus(); 
        sa=txtArea1.document.execCommand("SaveAs",true,"Say Thanks to Sumit.xls");
    }  
    else                 //other browser not tested on IE 11
        sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));  

    return (sa);
}

Just create a blank iframe:

<iframe id="txtArea1" style="display:none"></iframe>

Call this function on:

<button id="btnExport" onclick="fnExcelReport();"> EXPORT </button>

Datatable plugin solves the purpose best and allows us to export the HTML table data into Excel , PDF , TEXT. easily configurable.

Please find the complete example in below datatable reference link :

This could help

function exportToExcel(){
var htmls = "";
            var uri = 'data:application/vnd.ms-excel;base64,';
            var 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>{table}</table></body></html>'; 
            var base64 = function(s) {
                return window.btoa(unescape(encodeURIComponent(s)))
            };

            var format = function(s, c) {
                return s.replace(/{(\w+)}/g, function(m, p) {
                    return c[p];
                })
            };

            htmls = "YOUR HTML AS TABLE"

            var ctx = {
                worksheet : 'Worksheet',
                table : htmls
            }


            var link = document.createElement("a");
            link.download = "export.xls";
            link.href = uri + base64(format(template, ctx));
            link.click();
}

Instead of using window.open you can use a link with the onclick event.
And you can put the html table into the uri and set the file name to be downloaded.

Live demo :

function exportF(elem) {
  var table = document.getElementById("table");
  var html = table.outerHTML;
  var url = 'data:application/vnd.ms-excel,' + escape(html); // Set your html table into url 
  elem.setAttribute("href", url);
  elem.setAttribute("download", "export.xls"); // Choose the file name
  return false;
}
<table id="table" border="1">
  <tr>
    <td>
      Foo
    </td>
    <td>
      Bar
    </td>
  </tr>
</table>

<a id="downloadLink" onclick="exportF(this)">Export to excel</a>


You can use a library like ShieldUI to do that.

It supports exporting to both XML and XLSX widely-used Excel formats.

Regarding to sampopes answer from Jun 6 '14 at 11:59:

I have insert a css style with font-size of 20px to display the excel data greater. In sampopes code the leading <tr> tags are missing, so i first output the headline and than the other tables lines within a loop.

function fnExcelReport()
{
    var tab_text = '<table border="1px" style="font-size:20px" ">';
    var textRange; 
    var j = 0;
    var tab = document.getElementById('DataTableId'); // id of table
    var lines = tab.rows.length;

    // the first headline of the table
    if (lines > 0) {
        tab_text = tab_text + '<tr bgcolor="#DFDFDF">' + tab.rows[0].innerHTML + '</tr>';
    }

    // table data lines, loop starting from 1
    for (j = 1 ; j < lines; j++) {     
        tab_text = tab_text + "<tr>" + tab.rows[j].innerHTML + "</tr>";
    }

    tab_text = tab_text + "</table>";
    tab_text = tab_text.replace(/<A[^>]*>|<\/A>/g, "");             //remove if u want links in your table
    tab_text = tab_text.replace(/<img[^>]*>/gi,"");                 // remove if u want images in your table
    tab_text = tab_text.replace(/<input[^>]*>|<\/input>/gi, "");    // reomves input params
    // console.log(tab_text); // aktivate so see the result (press F12 in browser)

    var ua = window.navigator.userAgent;
    var msie = ua.indexOf("MSIE "); 

     // if Internet Explorer
    if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) {
        txtArea1.document.open("txt/html","replace");
        txtArea1.document.write(tab_text);
        txtArea1.document.close();
        txtArea1.focus(); 
        sa = txtArea1.document.execCommand("SaveAs", true, "DataTableExport.xls");
    }  
    else // other browser not tested on IE 11
        sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));  

    return (sa);
}

Requires an iframe

<iframe id="myIframe" style="opacity: 0; width: 100%; height: 0px;" seamless="seamless"></iframe>

Usage

$("#btnExportToExcel").click(function () {
    exportToExcel(this, '#mytable');
});

TableExport

TableExport - The simple, easy-to-implement library to export HTML tables to xlsx, xls, csv, and txt files.

To use this library, simple call the TableExport constructor:

new TableExport(document.getElementsByTagName("table"));

// OR simply

TableExport(document.getElementsByTagName("table"));

// OR using jQuery

$("table").tableExport(); 

Additional properties can be passed-in to customize the look and feel of your tables, buttons, and exported data. See here more info

You can use tableToExcel.js to export table in excel file.

This works in a following way :

1). Include this CDN in your project/file

<script src="https://cdn.jsdelivr.net/gh/linways/[email protected]/dist/tableToExcel.js"></script>

2). Either Using JavaScript:

<button id="btnExport" onclick="exportReportToExcel(this)">EXPORT REPORT</button>

function exportReportToExcel() {
  let table = document.getElementsByTagName("table"); // you can use document.getElementById('tableId') as well by providing id to the table tag
  TableToExcel.convert(table[0], { // html code may contain multiple tables so here we are refering to 1st table tag
    name: `export.xlsx`, // fileName you could use any name
    sheet: {
      name: 'Sheet 1' // sheetName
    }
  });
}

3). Or by Using Jquery

<button id="btnExport">EXPORT REPORT</button>

$(document).ready(function(){
    $("#btnExport").click(function() {
        let table = document.getElementsByTagName("table");
        TableToExcel.convert(table[0], { // html code may contain multiple tables so here we are refering to 1st table tag
           name: `export.xlsx`, // fileName you could use any name
           sheet: {
              name: 'Sheet 1' // sheetName
           }
        });
    });
});
