CSV to HTML Table
Paste CSV and instantly get a rendered HTML table plus ready-to-paste table markup.
Example
Input CSV:

Ada,Engineer
Grace,Admiral
Output HTML:
<table>
<thead>
<tr>
<th>name</th>
<th>role</th>
</tr>
</thead>
<tbody>
<tr>
<td>Ada</td>
<td>Engineer</td>
</tr>
<tr>
<td>Grace</td>
<td>Admiral</td>
</tr>
</tbody>
</table>
How it works
It parses CSV (RFC-4180 style quoting and escaped quotes) entirely in your browser, treats the first row as headers, and builds a semantic <table> with <thead> and <tbody>. The rendered preview and the HTML source update as you type.
Good to know
This CSV to HTML Table tool turns raw comma-separated data into a properly structured HTML table, using the first row as column headers (<th> inside <thead>) and every following row as body cells (<td> inside <tbody>). It's aimed at developers, technical writers, and content editors who have data in a spreadsheet or CSV export and need clean, semantic markup they can drop straight into a web page, CMS, email template, or documentation.
Reach for it whenever copy-pasting a spreadsheet into a rich-text editor would produce messy, inline-styled markup, or when you want a table you can fully control with your own CSS. Typical moments: publishing a pricing or specs table, embedding query results in a report, or quickly previewing how exported data will look as a real table before committing it to your codebase.
You get two outputs side by side. The "HTML source" pane is the code you copy, and the "Preview" pane renders that exact markup so you can confirm rows and columns line up before pasting. The status line reports how many rows were parsed (1 header plus N body rows), which is a fast sanity check: if the body count looks wrong, your CSV likely has stray line breaks or an unbalanced quote somewhere.
A few things worth knowing: the parser follows RFC-4180 quoting, so fields wrapped in double quotes can safely contain commas and line breaks, and it pads short rows so every row has the same number of cells as the header. It does not add CSS, IDs, classes, or accessibility attributes such as scope or a <caption>, so style and enhance the output yourself after pasting. Because everything runs locally in your browser, you can paste sensitive data without it being uploaded anywhere.
Frequently asked questions
How are quoted fields and commas inside cells handled?
The parser follows RFC-4180 rules: a field wrapped in double quotes can contain commas and line breaks, and a doubled quote ("") inside a quoted field becomes a single literal quote. So "Cambridge, UK" stays one cell.
Which row becomes the table header?
The first row is always used for thewithcells; every remaining row is rendered inwithcells. Short rows are padded so every column lines up with the header.
Is my data uploaded anywhere?
No — this tool runs entirely in your browser. Your input never leaves your device and it works offline once loaded.
Is it free?
Yes, completely free with no sign-up and no limits.
People also ask
How do I convert a CSV file to an HTML table?
Open your CSV in a text editor or spreadsheet, copy the data, paste it into the CSV input box, and the tool generates the HTML table source and a live preview. Then click Copy output and paste the markup into your page or CMS.
Does the first row of my CSV become the table header?
Yes. The first row is always treated as the header and rendered as th cells inside thead, while every row after it becomes a body row with td cells inside tbody.
What is a semantic HTML table and why does thead and tbody matter?
A semantic table separates header cells (th) from data cells (td) and groups them in thead and tbody sections. This improves accessibility for screen readers and makes the table easier to style and maintain than a generic grid of div elements.
Will the generated table include CSS styling?
No. The output is plain, unstyled semantic markup with no classes, inline styles, or borders. You apply your own CSS after pasting it, which keeps the markup clean and adaptable to your site's design.
Can it handle commas and line breaks inside a CSV cell?
Yes, as long as those values are wrapped in double quotes per RFC-4180. A quoted field like "Cambridge, UK" stays in one cell, and a doubled quote inside a quoted field becomes a single literal quote.
What happens if some rows have fewer columns than the header?
Shorter rows are padded with empty cells so every row matches the column count of the widest row. This keeps the table aligned, though it means missing values appear as blank td cells rather than being skipped.
Is it safe to paste private or confidential data into this tool?
The tool runs entirely in your browser and does not upload your input to any server, so your data stays on your device. As with any web page, only use a trusted, up-to-date browser and verify you are on the genuine site.
How is converting CSV to an HTML table different from importing it into a spreadsheet?
A spreadsheet import gives you an editable grid for calculations and analysis, whereas this tool outputs web-ready HTML markup meant to be embedded and displayed on a page. They serve different goals: data work versus publishing.
