How to convert CSV to an HTML table online

  1. Paste your data

    Paste or type CSV or TSV into the input. The delimiter is detected automatically, and you can override it to comma, tab, or semicolon.

  2. Choose your markup

    Toggle First row is header, add a class or a border, wrap the table in a responsive container, and pick pretty or minified output.

  3. Copy the HTML

    The table markup updates live as you type. Click Copy HTML to put it on your clipboard, or download it as an .html file.

Why use this tool

Converts as you type

There is no convert button. The HTML table regenerates on every edit, so the markup and the preview always match your input.

Automatic delimiter detection

Comma, tab, and semicolon separated data are detected for you, and you can force a specific delimiter when the guess is wrong.

Safe HTML escaping

Ampersands, angle brackets, and quotation marks in your data are turned into entities, so cell content renders as text instead of breaking the page.

Header, border, and class controls

Use the first row as a thead of th cells, add a class attribute for styling, add a visible border, or wrap the table in a scrollable container.

Pretty or minified output

Get indented, readable markup for editing by hand, or a single minified line ready to paste straight into a template.

Runs entirely in your browser

Your data is converted on your device and is never uploaded, so a spreadsheet full of records stays private.

About this tool

This tool turns delimited data into a clean HTML table. Paste CSV or TSV and the markup regenerates live as you type, with the delimiter detected from your data and an override for comma, tab, or semicolon files. Quoted fields are parsed properly, so a value wrapped in double quotes can hold commas, line breaks, and escaped quotes without splitting into extra columns. Every cell is escaped, so ampersands, angle brackets, and quotation marks in your data become safe entities that render as text instead of breaking the page.

Use the first row as the table header to get a thead of th cells, or turn the header off to render every row inside the tbody. Ragged rows are padded to the widest row so the columns line up, and a header-only file still produces a valid table. Choose pretty markup with indentation for readable source, or minified markup on a single line, and optionally add a class attribute, a visible border, or a responsive wrapper that scrolls wide tables on small screens.

CSV and TSV are what spreadsheets and database exports produce, while an HTML table is what a web page, email, or content management system expects. To parse the same data into structured records instead, use CSV to JSON, or to get documentation-ready output try CSV to Markdown Table. To tidy the generated markup further, open the HTML formatter. Everything here runs in your browser, so your data is never uploaded.

Frequently asked questions

How does the CSV to HTML table converter work?
Paste or type CSV or TSV and the HTML table updates live as you type. The first row is used as the header by default, the delimiter is detected automatically, and you can copy or download the result.
Is my data uploaded anywhere?
No. Everything runs in your browser; nothing is sent to a server. Your data never leaves your device and is not stored or logged.
Does it escape special characters in cells?
Yes. Ampersands, less-than and greater-than signs, and quotation marks are converted to HTML entities, so the values display as plain text and cannot break the surrounding page.
What delimiters and edge cases are handled?
Comma, tab, and semicolon are detected automatically, so both CSV and TSV work. Quoted fields, rows with missing cells, and header-only files are handled, with short rows padded to match the widest row.
Can I control the header, border, and formatting?
Yes. Toggle whether the first row is the header, add a class attribute or a visible border, wrap the table in a responsive container, and switch between pretty and minified markup.
