How to export tables in dashboard to Excel format using JavaScript?

Explorer

I got this code from CodexWorld(dot)com. How can I integrate this in a Splunk dashboard?

 function exportTableToExcel(tableID, filename = ''){
        var downloadLink;
        var dataType = 'application/vnd.ms-excel';
        var tableSelect = document.getElementById(tableID);
        var tableHTML = tableSelect.outerHTML.replace(/ /g, '%20');

        // Specify file name
        filename = filename?filename+'.xls':'excel_data.xls';

        // Create download link element
        downloadLink = document.createElement("a");

        document.body.appendChild(downloadLink);

        if(navigator.msSaveOrOpenBlob){
            var blob = new Blob(['\ufeff', tableHTML], {
                type: dataType
            });
            navigator.msSaveOrOpenBlob( blob, filename);
        }else{
            // Create a link to the file
            downloadLink.href = 'data:' + dataType + ', ' + tableHTML;

            // Setting the file name
            downloadLink.download = filename;

            //triggering the function
            downloadLink.click();
        }
    }

Then I put a button wrapped in an html tag, with putting an id in my table like this:

<html>
<button class="btn btn-primary" onclick="exportTableToExcel('tableid1', 'file-name')">Export Table Data To Excel File</button>
</html>

I also already tried using the Excel Export app at Splunkbase but I need to modify the code, to make the table headers in bold font weight and have dynamic column size depending on the text length of each headers.

Hi,

you have to create a javascript file in App/appserver/static/yourscriptname.js.

this file has to contain this:

require([
"splunkjs/mvc/simplexml/ready!"
], function() {

PUT YOUR CODE HERE

});

To reference this javascript file in your dashboard, you have to add it the header of the dashboard like this:

Hi @marxsabandana

Please refer this question (the requirements was almost similar) and see if it helps:
https://answers.splunk.com/answers/749857/how-to-make-a-second-download-button.html#answer-749318

I have provided an example of csv file. But you can try to change the format to xls and see if that works.
