CSV to table
Convert CSV into a Markdown or HTML table. Runs entirely in your browser, no upload.
About this tool
CSV to table turns CSV data into a ready-to-paste Markdown table (the
GitHub | a | b | style) or an HTML <table>.
- Markdown: a pipe table with a header separator row;
|and newlines in cells are escaped so the table stays valid. - HTML: a clean
<table>with<thead>/<tbody>; cell text is HTML-escaped. - Toggle whether the first row is a header (otherwise
Column Nheaders are made), and pick the delimiter (,/ tab /;/|).
Privacy
Everything runs in your browser via WebAssembly — your CSV is never uploaded. Also available from the gizza CLI and in chat.
Common uses
- Drop a spreadsheet selection into a README, issue, or PR as a Markdown table.
- Generate an HTML table for a web page or email.
FAQ
What if a cell contains a pipe character or a line break?
In Markdown output, | is escaped as \| and newlines inside a cell are
replaced with spaces, so the pipe table stays valid. In HTML output, &, <,
and > are escaped, so cell text can't inject markup.
My rows have different numbers of fields — will the table break?
No. The table is sized to the widest row, and shorter rows are padded with empty cells, so a ragged CSV still produces a rectangular table instead of an error.
Can I convert tab- or semicolon-separated data?
Yes — choose tab, semicolon, or pipe as the delimiter (comma is the
default), or supply any other single character. Pasting straight from a
spreadsheet usually means tab-separated.
What headers are used when my data has no header row?
Switch the header toggle off and the tool generates Column 1, Column 2, …
for you; every data row (including the first) then lands in the table body.
