TSV to HTML Table Converter
This TSV to HTML converter turns tab-separated text into a genuine HTML table rather than a pile of divs: the first line becomes th cells inside a thead, and every line after it becomes td cells inside a tbody. That structure is what screen readers and email clients expect, and it is what makes the table sortable and styleable later. 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. Everything runs in your browser.
How it works
Builds a real HTML table: the first line becomes <th> cells inside <thead> and every line after it 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 TSV to an HTML table
- Paste tab-separated text into the input on the left, or upload a
.tsvfile. - Choose a bare table to paste into an existing page, or a complete HTML document to save and open.
- Copy the markup on the right, or download it as an
.htmlfile.
Why the structure matters
It is easy to produce something that looks like a table and is not one. The output here uses real
<thead> and <tbody> sections with <th> cells for the
headings, because that structure is what everything downstream depends on: screen readers announce the column
name when reading a cell, email clients render it predictably, and sorting scripts and CSS
:nth-child rules can tell headings from data.
Escaping
Every cell is escaped before it reaches the markup. A value containing <b> is displayed as that
text rather than turning the rest of the row bold, and an ampersand becomes & so the page
stays valid. This matters most when the data came from somewhere you do not control.
Bare table or complete page
A bare <table> is what you want when pasting into a CMS, a blog post or an existing template.
The complete-document option wraps it in a doctype, head and minimal styling so you can save the file and open it
in a browser directly — useful for a quick shareable report.
Common use cases
- Publishing a spreadsheet extract on a web page or in a wiki.
- Building a table for an HTML email from data you already have.
- Turning a copied range into a self-contained file to send to someone.
Frequently asked questions
How do I convert TSV to an HTML table?
Paste your tab-separated text into the left panel or upload a .tsv file. The table markup appears on the right, ready to copy or download.
Does it produce a proper table structure?
Yes. The header line becomes th cells inside thead and the remaining lines become td cells inside tbody, which is what screen readers, email clients and sorting scripts expect.
Can I get a complete web page instead of just the table?
Yes. Tick the complete document option and you get a full HTML file with a doctype and head that you can save and open in a browser directly.
Is my data escaped?
Yes. Ampersands, angle brackets and quotes are escaped, so a value containing markup is displayed as text instead of being interpreted.
What if my data has no header row?
Untick the header option and every line is treated as a data row, producing a table with a tbody only.
Is anything uploaded?
No. The conversion happens entirely in your browser.
