Question

How can I convert it into excel file with grouping, something like this:

Answer 1

Im not to sure about the grouping in XLS but the main way we convert data into XL is to use CSV

You can parse the data from your HTML into an array then export that array to CSV

Here is the code to make your html table downloadable to CSV

 var data = [ ['Foo', 'programmer'], ['Bar', 'bus driver'], ['Moo', 'Reindeer Hunter'] ]; function download_csv() { var csv = 'Name,Title\\n'; data.forEach(function(row) { csv += row.join(','); csv += "\\n"; }); console.log(csv); var hiddenElement = document.createElement('a'); hiddenElement.href = 'data:text/csv;charset=utf-8,' + encodeURI(csv); hiddenElement.target = '_blank'; hiddenElement.download = 'people.csv'; hiddenElement.click(); }

 <button onclick="download_csv()">Download CSV</button>
