How to convert CSV to an HTML table

1. Paste your CSV into the input box above (or click Upload to load a file).
2. Make sure HTML Table is selected as the output format.
3. Confirm that First row as header is checked if your CSV has column names in row 1.
4. Click Convert — your HTML appears instantly in the output panel.
5. Click Copy or Download to grab the result.

That's it — no account, no email, no waiting. The output is a standard <table> with <thead> and <tbody> sections, ready to drop into any HTML page or template.

Worked example: product catalogue CSV → HTML

Say you export a product list from a spreadsheet and get this CSV:

Product,Price,In Stock
"Running Shoes, Pro",89.99,true
Yoga Mat,24.50,true
Dumbbells (10kg),34.00,false

Notice the quoted field "Running Shoes, Pro" — it contains a comma, so it's wrapped in quotes. The converter handles that automatically.

The resulting HTML table looks like this:

<table>
  <thead>
    <tr>
      <th>Product</th>
      <th>Price</th>
      <th>In Stock</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Running Shoes, Pro</td>
      <td>89.99</td>
      <td>true</td>
    </tr>
    <tr>
      <td>Yoga Mat</td>
      <td>24.50</td>
      <td>true</td>
    </tr>
    <tr>
      <td>Dumbbells (10kg)</td>
      <td>34.00</td>
      <td>false</td>
    </tr>
  </tbody>
</table>

Paste that directly into your HTML file or CMS and you get a properly structured table — no extra clean-up needed.

How to do this in Python or JavaScript

If you need to automate this conversion in code, here are the quickest paths in the two most common languages.

Python

import csv

def csv_to_html_table(csv_text):
    reader = csv.reader(csv_text.splitlines())
    rows = list(reader)
    if not rows:
        return ''
    headers = rows[0]
    body_rows = rows[1:]

    th = ''.join(f'<th>{h}</th>' for h in headers)
    thead = f'<thead><tr>{th}</tr></thead>'

    tbody_rows = []
    for row in body_rows:
        tds = ''.join(f'<td>{cell}</td>' for cell in row)
        tbody_rows.append(f'<tr>{tds}</tr>')
    tbody = f'<tbody>{"".join(tbody_rows)}</tbody>'

    return f'<table>{thead}{tbody}</table>'

csv_data = "Name,Score\nAlice,92\nBob,74"
print(csv_to_html_table(csv_data))

Python's built-in csv module handles quoted fields and escaped commas correctly. No third-party library needed.

JavaScript (browser or Node.js)

function csvToHtmlTable(csvText) {
  const rows = csvText.trim().split('\n').map(r => r.split(','));
  const [headers, ...bodyRows] = rows;

  const th = headers.map(h => `<th>${h.trim()}</th>`).join('');
  const thead = `<thead><tr>${th}</tr></thead>`;

  const tbody = bodyRows.map(row => {
    const tds = row.map(cell => `<td>${cell.trim()}</td>`).join('');
    return `<tr>${tds}</tr>`;
  }).join('');

  return `<table>${thead}<tbody>${tbody}</tbody></table>`;
}

console.log(csvToHtmlTable('Name,Score\nAlice,92\nBob,74'));

Note: this snippet splits on commas naively — it won't handle quoted fields containing commas. For production use, reach for a library like Papa Parse, which follows the RFC 4180 CSV spec and handles edge cases correctly.

How the converter works

The tool parses your pasted CSV according to RFC 4180 — the standard that defines how CSV files should be structured. That means it correctly handles fields that contain commas inside double quotes, line breaks inside cells, and escaped quote characters.

Once parsed, it builds a DOM-safe HTML table: the first row becomes <th> header cells inside <thead>, and every subsequent row becomes <td> data cells inside <tbody>. Special HTML characters like <, >, and & inside your data are escaped automatically so they render as text rather than breaking your markup.

All processing runs in your browser. Your CSV data is never uploaded to any server, so it's safe to use with sensitive or internal data.
