Question 1

Does this build an HTML table from my TSV?

Accepted Answer

No. It wraps the whole input in one pre block. For real table markup with rows and cells, use the CSV to HTML Table Converter, or paste your TSV into a spreadsheet and export it as HTML.

Question 2

Will special characters in my data break the output?

Accepted Answer

No. Angle brackets and ampersands are HTML-escaped before being wrapped, so a value like A & B renders as text rather than being interpreted as markup.

Question 3

Is my data uploaded anywhere?

Accepted Answer

No. The conversion runs entirely in JavaScript in your browser tab; nothing is sent to a server.

Question 4

Can I convert the other direction, HTML back to TSV?

Accepted Answer

Yes. Switch Convert as to HTML to TSV, which reads an HTML table's rows and cells and writes them out as tab-separated text.
