Markdown Table Generator

How this reads your output

The separator is detected from what you paste, with tabs taking priority because copying a range out of a spreadsheet puts tab-separated text on the clipboard. That means selecting cells and pasting works with no export step. Existing Markdown tables are accepted too and simply reformatted, with the separator row rebuilt to match the new column widths.

What the results mean

Detected separator

Tab, comma or pipe. Tabs win when present, since spreadsheet clipboard data uses them and commas inside values would otherwise split cells.

Ragged rows

Rows with a different cell count from the header. They are padded to match, which keeps the table valid but is worth checking.

Column widths

Measured across every row so the raw text lines up. Purely for readability in the source file.

Common problems and fixes

Pasting from a spreadsheet splits cells wrongly

A value containing a tab is the usual cause, which happens when text was pasted into the spreadsheet from somewhere else. Find and remove the stray tabs in the source, or export as CSV and use the CSV converter instead, which handles quoted fields properly.

The first row is treated as data rather than a header

Markdown tables require a header, so the first row always becomes one. If your data has no header, add a row of column names before pasting; every renderer expects one and a table without it will not display.
