Sometimes you face the problem to export the data into csv file using clientside platform. In this case you can use javascript and jquery.

Below is the code to find out the solution:

Javascript Code:

 $(document).ready(function () {

    function exportTableToCSV($table, filename) {

        var $rows = $table.find('tr:has(td)'),

            // Temporary delimiter characters unlikely to be typed by keyboard
            // This is to avoid accidentally splitting the actual contents
            tmpColDelim = String.fromCharCode(11), // vertical tab character
            tmpRowDelim = String.fromCharCode(0), // null character

            // actual delimiter characters for CSV format
            colDelim = '","',
            rowDelim = '"\r\n"',

            // Grab text from table into CSV formatted string
            csv = '"' + $rows.map(function (i, row) {
                var $row = $(row),
                    $cols = $row.find('td');

                return $cols.map(function (j, col) {
                    var $col = $(col),
                        text = $col.text();

                    return text.replace('"', '""'); // escape double quotes

                }).get().join(tmpColDelim);

            }).get().join(tmpRowDelim)
                .split(tmpRowDelim).join(rowDelim)
                .split(tmpColDelim).join(colDelim) + '"',

            // Data URI
            csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);

        $(this)
            .attr({
            'download': filename,
                'href': csvData,
                'target': '_blank'
        });
    }

    // This must be a hyperlink
    $(".export").on('click', function (event) {
        // CSV
        exportTableToCSV.apply(this, [$('#dvData>table'), 'export.csv']);

        // IF CSV, don't do event.preventDefault() or return false
        // We actually need this to be a typical hyperlink
    });
});

HTML Code:

<div id="dvData">
    <table>
        <tr>
            <th>Column One</th>
            <th>Column Two</th>
            <th>Column Three</th>
        </tr>
        <tr>
            <td>row1 Col1</td>
            <td>row1 Col2</td>
            <td>row1 Col3</td>
        </tr>
        <tr>
            <td>row2 Col1</td>
            <td>row2 Col2</td>
            <td>row2 Col3</td>
        </tr>
        <tr>
            <td>row3 Col1</td>
            <td>row3 Col2</td>
            <td>row3 Col3</td>
        </tr>
    </table>
</div>
