What MediaWiki table format does it output?+
Standard wikitable markup: {| class="wikitable" to open, |+ for an optional caption, ! cells for the header row, |- to separate rows, | cells for data, and |} to close. It's the same syntax used across Wikipedia, Fandom, and any MediaWiki install.
How are pipes inside my data handled?+
The pipe character is MediaWiki's cell delimiter, so a literal | in your content would split a cell, start a new one with ||, or end the table with |}. We escape every literal pipe to the HTML entity |, which the wiki renders as a normal | without breaking the markup.
What happens to cells that contain line breaks?+
Wikitable rows are line-oriented — a raw newline inside a cell would break the row. We collapse any newline run to a single space so the cell stays on one line and the table stays valid.
Can I add a caption or sortable columns?+
Yes. Set a caption to emit a |+ caption line above the header, and toggle 'sortable' to add the sortable class so readers can click headers to sort. Both are optional — leave them off for a plain wikitable.
Does my CSV leave the browser?+
No. Everything runs locally in your browser — parsing, escaping, and rendering. There's no server upload, and you can verify it yourself in DevTools → Network.
