CSV to HTML Table Converter

Convert CSV to a clean HTML table with thead and tbody. Free in-browser converter — no upload, copy-paste ready markup.

Need tabular data on a web page? This converter produces clean, semantic HTML — a proper <table> with <thead> and <tbody> — from any CSV, ready to paste into your site or CMS.

All cell content is HTML-escaped, so angle brackets and ampersands in your data won't break the page or open an XSS hole.

Example

Input
name,city
Ada,London
Output
<table>
  <thead>
    <tr><th>name</th><th>city</th></tr>
  </thead>
  <tbody>
    <tr><td>Ada</td><td>London</td></tr>
  </tbody>
</table>

Your data never leaves your device

Like everything at OpenCSV, this tool processes files locally in your browser. There is no upload, no server-side processing, and no copy of your data anywhere — which makes it safe for customer lists, financial exports, and other sensitive files.
