What you can paste
Comma or semicolon separated CSV (quoted cells with commas or line breaks inside are handled), tab-separated cells copied straight out of Excel, Google Sheets or Numbers, existing Markdown pipe tables, and plain text where columns are lined up with two or more spaces, such as terminal output.
Header and alignment
If the first row is all text and the rows below hold numbers, it's treated as the header. You can override that. In Markdown and HTML, number columns are right-aligned so digits line up; pick an alignment to apply the same to every column instead.
Using the LaTeX output
The tabular uses only \hline, so it works without extra packages. Special characters such as &, %, $ and _ are escaped. Wrap it in a table environment to add a caption.
