CSV to HTML Table Converter
This CSV to HTML converter builds real table markup rather than a grid of divs: the header row becomes th cells inside thead and the remaining rows become td cells inside tbody. That structure is what screen readers use to announce which column a cell belongs to, so the result is accessible by default instead of needing ARIA attributes added afterwards. Every cell is HTML-escaped on the way out, so an ampersand, an angle bracket or a stray script tag in your spreadsheet renders as text rather than being interpreted as markup — which matters whenever the data came from somewhere you do not control. Output either a bare table to paste into a page, or a complete styled HTML document you can save and open.
How it works
Builds a real HTML table: the header row becomes <th> cells inside <thead>, and every other row becomes <td> cells inside <tbody>. All content is escaped, so ampersands and angle brackets in your data cannot break the markup.
Choose a bare table to paste into an existing page, or a complete HTML document you can save and open directly.
The conversion runs entirely in your browser — nothing you paste or upload is sent to a server.
How to convert CSV to an HTML table
- Paste your CSV, or upload a
.csv/.tsvfile. - Set the delimiter and say whether the first row holds column names.
- Copy the markup to paste into a page, or switch on Complete HTML document and download a file you can open directly.
Proper table markup, not a grid of divs
The header row becomes <th> cells inside <thead>, and the remaining rows
become <td> cells inside <tbody>. That structure is what screen readers use
to announce which column a cell belongs to, so the result is accessible by default rather than needing ARIA
attributes bolted on afterwards.
Your data cannot break the page
Every cell is HTML-escaped on the way out, so an ampersand, a less-than sign or a stray <script>
in your spreadsheet is rendered as text rather than interpreted as markup. This matters whenever the CSV came from
somewhere you do not control.
Common use cases
- Dropping a data table into a blog post, wiki page or documentation site.
- Turning an export into a shareable page without a spreadsheet app.
- Building a quick printable view of tabular data.
Frequently asked questions
How do I turn a CSV into an HTML table?
Paste your CSV or upload a .csv or .tsv file. The markup appears on the right — copy it into a page, or switch on the complete document option and download a file you can open directly in a browser.
Is the generated table accessible?
Yes. The header row becomes th cells inside thead and the data rows become td cells inside tbody, which is the structure screen readers use to announce which column a cell belongs to. No extra ARIA attributes are needed.
What happens to special characters in my data?
Every cell is HTML-escaped, so ampersands, angle brackets and anything resembling a tag are rendered as visible text rather than interpreted as markup. Untrusted spreadsheet content cannot break or inject into the page.
Can I get a complete web page instead of a snippet?
Yes. Turn on the complete document option and the output includes a doctype, head, character encoding and a small stylesheet, so the downloaded file opens as a finished page.
Can I style the table myself?
Yes. The markup uses plain table, thead, tbody, th and td elements with no classes attached, so your own stylesheet applies to it directly.
Is my CSV uploaded anywhere?
No. The file is read and converted entirely in your browser, so the data never leaves your device.
