In one of the project, I needed to create the CSV file from the html using jQuery.

To make this possible, I created the below code to convert the html into csv file using jQuery.

<script type="text/javascript" src="jquery.min.js"></script>

<hr>
<div id="dvData">
    <table class="mustBe" border="1">
        <tr>
            <td>Column One</td>
            <td>Column Two</td>
            <td>Column Three</td>
                        <td>Column One</td>
            <td>Column Two</td>
            <td>Column Three</td>

        </tr>
        <tr>
            <td>1</td>
            <td>Rs. 1,22.5</td>
            <td>3</td>
                        <td>Column One</td>
            <td>Column Two</td>
            <td>Column Three</td>

        </tr>
        <tr>
            <td>4</td>
            <td>5.121</td>
            <td>6.91</td>
                        <td>Column One</td>
            <td>Column Two</td>
            <td>Column Three</td>

        </tr>
        <tr>
            <td>7</td>
            <td>212 8.11</td>
            <td>9</td>
                        <td>Column One</td>
            <td>Column Two</td>
            <td>Column Three</td>

        </tr>
    </table>
