<h2>File Upload and Data Transformation</h2>
Upload the <b>sample_input.txt</b> located in this example folder.
<br>
<br>
V will apply data transformation, adding the first two columns into a third column, and return the results as a download. <br>
<br>
For example:
<table style="color:blue;">
<tr>
<td>10</td>
<td>13</td>
</tr>
<tr>
<td>20</td>
<td>54</td>
</tr>
<tr>
<td>30</td>
<td>82</td>
</tr>
<tr>
<td>40</td>
<td>11</td>
</tr>
<tr>
<td>50</td>
<td>47</td>
</tr>
</table>
<br>
Becomes...
<br>
<table style="color:blue;">
<tr>
<td>10</td>
<td>13</td>
<td>23</td>
</tr>
<tr>
<td>20</td>
<td>54</td>
<td>74</td>
</tr>
<tr>
<td>30</td>
<td>82</td>
<td>112</td>
</tr>
<tr>
<td>40</td>
<td>11</td>
<td>51</td>
</tr>
<tr>
<td>50</td>

</tr>
</table>
