Markdown Table Generator
Markdown Table Generator turns a grid you fill in into GitHub-flavoured table syntax.
How to use it
- Fill in the header row and add rows or columns as needed
- Type into each cell — the Markdown table updates automatically
- Copy the generated Markdown with one click
The first row is the header, and the separator row is always three dashes per column — there is no alignment option, so left, right and centre markers cannot be produced. Each cell is trimmed; a pipe inside a cell is escaped and a line break becomes a single space, so a cell can never break the table. Empty cells are kept as blank columns, and short rows are padded to the column count. The output is plain text to copy — there is no rendered preview here, so paste it into Markdown Editor & Preview to see it. A table may hold up to 1,000 rows and 20,000 cells within a 1 MB budget, and nothing leaves the browser.
FAQ
No. Every separator cell is three dashes; the generator never emits the colon markers for left, right or centre, so all columns use the renderer's default alignment.
A pipe is escaped so it stays literal, and any line break is replaced with a space, so the cell stays on one table row. Cells are also trimmed.
Up to 1,000 rows and 20,000 cells in total, inside a 1 MB input budget. Empty cells are allowed and render as blank columns.
