About this tool
Hand-writing table markup is tedious and easy to get wrong: a missing closing tag, a forgotten thead, or an unescaped ampersand that breaks the page. Generating it removes all three risks.
The output uses proper thead and tbody sections with th elements carrying scope="col", which is what screen readers rely on to announce column context. Every cell value is HTML-escaped, so data containing angle brackets cannot inject markup.
How to use this tool
- Paste CSV or upload a file, and confirm the delimiter.
- Choose whether the first row is a header row.
- Optionally add a caption and CSS class names for the table.
- Press Convert and copy the generated markup.
Key features
- Semantic thead, tbody and scoped th elements
- Every cell HTML-escaped against markup injection
- Optional caption element for accessibility
- Custom CSS classes on the table element
- Indented, readable markup
- Delimiter auto-detection for pasted data
Example
Input — CSV
city,pop
Seoul,9.7MOutput — HTML
<table>
<thead>
<tr><th scope="col">city</th><th scope="col">pop</th></tr>
</thead>
<tbody>
<tr><td>Seoul</td><td>9.7M</td></tr>
</tbody>
</table>Good to know
- No CSS is generated. The table inherits whatever styles your page defines.
- Column spans and row spans cannot be expressed in CSV, so every cell is a single cell.
- Very large tables produce very large markup; consider pagination or a data grid component beyond a few thousand rows.
Frequently asked questions
Why does the header use scope="col"?
It tells assistive technology which header applies to which cells. Without it, a screen reader announces values with no context, which makes a table close to unusable.
Is the content safe to embed?
Cell values are escaped, so characters like < and & appear as text rather than markup. Standard care with untrusted data still applies in your own pipeline.
Can I get a styled table?
Add your own class names in the options and style them in your stylesheet. Inline styles are deliberately avoided so the markup stays portable.
Does it add sorting or filtering?
No. The output is static markup. Interactive behaviour belongs to a JavaScript table component in your application.
