How it works — in four simple steps

No signup and nothing to install — it all runs in your browser.

Add your CSV

Paste it into the left box, press Open file, or drag a .csv file onto it. Sample loads a realistic example.

Set the options

Adjust the options above the boxes — the output updates instantly as you change them.

Check the result

Read the status line: it reports rows, keys and any value that couldn't be represented in HTML table.

Copy or download

Copy the HTML table or download it as a .html file. Nothing was uploaded at any point.

Pro tip

Wrap wide tables in a div with overflow-x:auto so they scroll on phones.

Features

Delimiter auto-detection

Comma, semicolon, tab or pipe is sniffed from the first lines — European Excel exports with ; just work.

Header row or not

Use the first row as field names, or treat every row as data with generated column1, column2… names.

Accessible markup

Header cells get scope="col", and you can add a <caption> and a CSS class for styling.

Readable or compact

Padded columns that line up in a code editor, or compact output for the smallest diff.

Private by design

Parsing and conversion run in your browser with JavaScript — your data is never uploaded, logged or stored.

About the CSV to HTML table Converter

Putting a spreadsheet on a web page, in an email template or in a CMS that accepts HTML means writing table markup by hand — or pasting from Excel and getting kilobytes of inline styles. This generator produces the minimal, semantic version: <table>, an optional <caption>, a <thead> with <th scope="col"> for each header and a <tbody> of <td> rows.

Semantic markup matters for accessibility: screen readers use th with scope to announce which column a cell belongs to, and the caption to describe the table. All cell content is HTML-escaped (<, >, &, quotes), so data containing angle brackets can't break your page or inject markup.

Add a CSS class to hook into your framework's table styles — table table-striped for Bootstrap, or your own — and tick Compact for single-line markup to paste into an email builder.

Examples

A price list with a caption, a Bootstrap class and a value containing an ampersand and angle brackets.

CSV input

Plan,Monthly,Annual,Includes
Starter,₹299,"₹2,990",1 site & email support
Growth,₹799,"₹7,990","5 sites, <API> access"
Scale,"₹1,999","₹19,990",Unlimited sites

HTML table output

<table class="table table-striped">
  <caption>Hosting plans</caption>
  <thead>
    <tr>
      <th scope="col">Plan</th>
      <th scope="col">Monthly</th>
      <th scope="col">Annual</th>
      <th scope="col">Includes</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Starter</td>
      <td>₹299</td>
      <td>₹2,990</td>
      <td>1 site &amp; email support</td>
    </tr>
    <tr>
      <td>Growth</td>
      <td>₹799</td>
      <td>₹7,990</td>
      <td>5 sites, &lt;API&gt; access</td>
    </tr>
    <tr>
      <td>Scale</td>
      <td>₹1,999</td>
      <td>₹19,990</td>
      <td>Unlimited sites</td>
    </tr>
  </tbody>
</table>

This output was produced by the converter on this page with caption “Hosting plans” and class table table-striped — load it with the “Price list” preset above and change any option to see the effect.

How CSV maps to HTML table

In CSV	Becomes in HTML table
Header row	`<thead><tr><th scope="col">…`
Data rows	`<tbody><tr><td>…`
Caption box	`<caption>…</caption>`
CSS class box	`<table class="…">`
`<b>` in data	`<b>` (shown as text)
Empty cell	`<td></td>`

Things that trip people up

HTML in your data is escaped. That's deliberate and safe. If you want links or bold inside cells, edit the generated markup afterwards.
No styling included. The table is unstyled on purpose; add a class or a few CSS rules (border-collapse, padding) in your site's stylesheet.
Wide tables on phones. Wrap the table in a <div style="overflow-x:auto"> so it scrolls horizontally instead of breaking your layout.
Email clients. Many email clients ignore stylesheets; use Compact output and inline styles from your email builder.

CSV vs HTML table at a glance

Property	CSV	HTML table
Specification	RFC 4180 (2005)	HTML Living Standard (WHATWG)
File extension	.csv	.html
Media type	text/csv	text/html
Data types	text only — every cell is a string	text (any inline HTML)
Comments	No	Yes <!-- -->
Nesting	None (flat rows)	Cells can span rows/columns

CSV: Fields containing a comma, a double quote or a line break must be wrapped in double quotes, and a quote inside is written twice ("").
HTML table: Use for header cells and a so screen readers can announce the table properly.

Frequently asked questions

5 answers

How do I convert CSV to an HTML table?

Paste the CSV, optionally add a caption and class, and copy the generated markup into your page or CMS.

Is the generated table accessible?

Yes. It uses thead/tbody, th with scope="col" and an optional caption, which screen readers rely on to announce headers.

Can I style it with Bootstrap or Tailwind?

Yes — put the classes in the CSS class box, e.g. table table-striped for Bootstrap; for Tailwind add utility classes in your own CSS.

Is my data safe to embed?

All values are HTML-escaped, so characters like < and & can't break the page or inject markup.

Is my data uploaded anywhere?

No. The CSV is parsed and converted by JavaScript in your browser tab; nothing is sent to a server, so it is safe for internal exports, customer lists and configuration files with secrets.
