What it does

This tool turns CSV data into an HTML table. The first row becomes the table header (<th> cells inside <thead>), and every other row becomes a <tr> in <tbody>. The markup is indented and free of inline styles, so it is easy to read, edit and style.

Use it to publish a spreadsheet on a website, put a table in a blog post or newsletter, or document data in an HTML page.

How to use

  1. Paste CSV into the Input box, upload a .csv file, or click Sample.
  2. The HTML appears on the right as you type.
  3. Choose the Delimiter if auto-detection picks the wrong one, and turn First row is header off if your data has no header.
  4. Copy the HTML or download it as an .html file.

Example

name,city
Alice,Shanghai

becomes

<table>
  <thead>
    <tr>
      <th>name</th>
      <th>city</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Alice</td>
      <td>Shanghai</td>
    </tr>
  </tbody>
</table>

Notes

Rows with fewer cells than the widest row are padded with empty cells, so every row has the same number of columns.

FAQ

› Can I style the generated table?

Yes. The output is plain <table>, <thead>, <tbody>, <tr>, <th> and <td> markup without inline styles, so it picks up your site's CSS. Add a class to the <table> tag to target it.

› What if my CSV has no header row?

Turn off "First row is header". All rows are then written as data rows and no <thead> is generated.

› Are special characters safe?

Yes. <, >, & and quotes are escaped, so cell content is shown as text and cannot inject HTML. Line breaks inside a cell become <br>.

› Is there a size limit?

Inputs up to 1 MB convert as you type; larger files switch to manual mode, so press Run.
