Converting CSV (Comma-Separated Values) to an HTML Table is a common task when you need to display CSV data on a webpage. HTML tables provide a structured way to present data, and converting CSV into HTML helps in making the data easily accessible and viewable on websites or web applications.
Why convert CSV to HTML Table?
✅ Display Data on Web Pages: An HTML table is ideal for presenting structured data like CSV content on web pages.
✅ Easy to Style: HTML tables can be styled using CSS to improve the appearance, making them more user-friendly and visually appealing.
✅ Better Integration with Web Applications: Converting CSV to HTML makes it easy to integrate CSV data into dynamic websites or applications that need to present large amounts of tabular data.
Example of CSV to HTML Table Conversion:
CSV Input:
csv
name,age,city
Alice,30,New York
Bob,25,Los Angeles
Charlie,35,Chicago
HTML Table Output:
html
<table border="1">
<thead>
<tr>
<th>name</th>
<th>age</th>
<th>city</th>
</tr>
</thead>
<tbody>
<tr>
<td>Alice</td>
<td>30</td>
<td>New York</td>
</tr>
<tr>
<td>Bob</td>
<td>25</td>
<td>Los Angeles</td>
</tr>
<tr>
<td>Charlie</td>
<td>35</td>
<td>Chicago</td>
</tr>
</tbody>
</table>
This HTML code creates a table where the CSV data is displayed in rows and columns, with headers for each field (name, age, city).
