TSV and HTML explained

TSV is CSV with tab characters as separators. Because tabs almost never appear inside data fields, it sidesteps most of CSV's quoting problems.

HTML is the markup language of the web, describing document structure — headings, paragraphs, lists, links — which browsers then render.

Where TSV files come from
Bioinformatics, data pipelines and anywhere fields contain commas.
Where HTML is used
Web pages, email templates and exports from documentation tools.

TSV vs HTML

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

Why convert TSV to HTML?

People make this switch when they run into the limits of TSV: handing files to non-technical recipients. HTML is the better fit when publishing on the web or generating documents programmatically.

TSV limitations that prompt the switch
Tabs are invisible, making manual editing error-prone. Less universally recognised than CSV.
What you give up
Layout depends on the renderer and available fonts. Not a fixed-layout format.

What is preserved when converting TSV to HTML?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.
