How to Convert TSV to an HTML Table
Dropping tabular data into a web page usually means hand-writing rows of tags — tedious and easy to get wrong. This converter does it instantly. Paste your tab-separated data and it builds a clean, semantic HTML table: the first row becomes th cells inside a thead, the rest become td cells inside a tbody, and every value is HTML-escaped so stray angle brackets never break your markup. Add a CSS class to match your framework, choose pretty or minified output, and check the live preview to see the rendered result. Everything runs in your browser, so nothing is uploaded.
Paste your TSV
Paste tab-separated data or load the sample; it's parsed locally with nothing uploaded.
Style the table
Add a CSS class and toggle the header row, minify and trimming.
Copy or download
Grab the HTML with one tap or save it as an .html file.
TSV vs HTML Tables — What's the Difference?
TSV — tab-separated values
A plain-text grid where tabs separate columns. It's compact and perfect for storing or moving data, but browsers don't render it as a table — paste it into a web page and you just get a run of text. It's the source, not the presentation.
HTML table markup
A structured set of table, thead, tbody, tr, th and td elements that browsers render as a real, styleable grid. It's what you embed in a page, style with CSS, and make accessible with proper header cells. Converting TSV to HTML turns raw data into presentation-ready markup.
Common Use Cases
Embed data in a page
Turn a spreadsheet range into a ready-to-paste HTML table for your website.
Blog & docs tables
Generate clean table markup for articles, documentation and knowledge bases.
Email templates
Produce simple, semantic tables for HTML emails and newsletters.
Framework-ready
Add a Bootstrap or Tailwind class so the table matches your design instantly.
CMS content
Paste generated markup into a CMS that accepts raw HTML.
Reports & dashboards
Drop tabular results into internal reports and static dashboards.
Prototyping
Quickly mock up tables with real data while building a UI.
Accessibility
Get proper th header cells that screen readers can announce correctly.
Tips & Best Practices
Keep a header row
A real header becomes th cells, which improves accessibility and lets you style column headers separately.
Use a framework class
Add your framework's table class so the output matches your existing design with zero extra CSS.
Minify for production
Use minified output when embedding in a live page, and pretty output when you'll edit the markup by hand.
Trim to avoid gaps
Trimming removes stray spaces that can create odd padding inside cells.
Check the preview
The live preview shows exactly how the table renders before you copy the markup.
Troubleshooting
Everything is in one column
Your data probably isn't tab-delimited. Ensure columns are separated by real tabs — copying from a spreadsheet guarantees this.
The table has no styling
Raw HTML tables are unstyled by default. Add a CSS class matching your framework, or wrap the output in your own styles.
My HTML characters show as text
That's intentional escaping so your data can't break the page. Angle brackets in data appear as visible characters, which is the safe behaviour.
No header appears
Turn on the header row option so the first row becomes th cells inside a thead.
Frequently Asked Questions
How do I convert TSV to an HTML table for free?
Paste your tab-separated data above and semantic HTML table markup appears instantly, with a live preview. Copy it or download an .html file — free, no signup.
Does it create a proper thead?
Yes. With the header option on, the first row becomes th cells inside a thead, and the remaining rows become td cells inside a tbody.
Can I add a CSS class?
Yes. Enter any class names — like 'table table-striped' — and they're added to the table element so it matches your framework.
Is my data HTML-escaped?
Yes. Ampersands and angle brackets in your values are escaped so they display as text and can't break your page markup.
Can I get minified HTML?
Yes. Turn on minify for compact markup with no extra whitespace, ideal for production pages.
Is there a live preview?
Yes. The rendered table is shown right below the markup so you can see exactly what you'll get.
Can I make a table without a header?
Yes. Turn off the header option and every row becomes a body row of td cells.
Will it work with Bootstrap or Tailwind?
Yes. Add the relevant class names and the generated table slots straight into your framework's styles.
Does trimming affect my data?
It only removes leading and trailing spaces from each cell for cleaner output.
Is my data sent to a server?
No. Everything happens inside your browser, so your data never leaves your device.
Can I download the result?
Yes. Save the output as an .html file, or copy it straight to your clipboard.
How large a table can it handle?
It comfortably converts tables with many hundreds of rows, all in your browser.
Does it preserve empty cells?
Yes. Empty values become empty td cells so your columns stay aligned.
Can I paste it into an email?
Yes. The markup is simple and semantic, which suits HTML emails; add inline styles if your email client needs them.
Does it work on phones?
Yes, in any modern browser on Windows, Mac, Android or iPhone with nothing to install.
Is this converter really free?
