How to create a .CSV file from a HTML table (MVC5)

I would like to know how to create a .CSV file from a HTML table. I have a Jquery code to create a .XLS file from an HTML table. But, I want to create .CSV file. Can anyone help me to figure it out?

This is the code to create a .XLS file from HTML table

function fnExcelReport() {
            var tab_text = "<table border='2px'><tr bgcolor='#87AFC6'>";
            var textRange; var j = 0;
            tab = document.getElementById('table1'); // 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, "QI.xls");
            }
            else                 //other browser not tested on IE 11
                sa = window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));

            return (sa);
        }
    });

Thanks.
