Markdown Table Generator with Excel and CSV Paste

Make a Markdown table without counting pipes

Markdown tables are easy to read and tedious to write: every row needs the right number of pipes, the second line needs a separator for each column, and one missing | breaks the whole table. This Markdown table generator gives you a spreadsheet-style grid instead. Type into the cells, add or remove rows and columns with the buttons, and the Markdown underneath updates as you go. The first row is the header.

Each column has an alignment control that cycles through default, left, center and right, which writes the matching separator (---, :---, :---: or ---:). With pretty output on, every column is padded to the same width so the raw Markdown lines up and stays readable in a code review or a plain-text editor; wide characters such as Chinese text and emoji count as two columns for that padding. Turn it off for compact output with no padding — renderers treat both forms identically. The trade-off shows up in version control: pretty output reads better, but making one cell wider than the rest of its column re-pads every row, while compact output keeps diffs to the lines you actually changed.

The output is GitHub Flavored Markdown (GFM) table syntax, which is what GitHub, GitLab, Bitbucket, Notion imports, Obsidian, Docusaurus, MkDocs and most static site generators understand. Original Markdown from 2004 has no table syntax at all, so if a renderer shows your table as raw pipes, it probably does not support GFM.

Excel paste, CSV to Markdown table, and importing existing tables

To convert a spreadsheet, select the cells in Excel or Google Sheets, copy, and paste into any cell of the grid. Spreadsheets put tab-separated text on the clipboard, and the grid spreads it across rows and columns starting from the cell you pasted into, growing the table if needed. For a CSV to Markdown table conversion, paste the file contents into the import box instead: the delimiter (comma, semicolon or tab) is detected from the first line, and quoted fields are handled properly, including commas, doubled quotes and line breaks inside quotes.

The same import box also reads Markdown. Paste an existing table — from a README you need to edit, say — and it is parsed back into the grid with its alignment, so you can add a column or reorder data without hand-editing pipes. Only the first table in the pasted text is imported, and rows with fewer cells are padded.

Escaping and cell content

A literal | inside a cell would end the cell early, so pipes are written as \| automatically and turned back into | when a table is imported. Line breaks inside a cell, which GFM tables cannot contain, are written as <br>, which GitHub and most renderers display as a line break. Inline Markdown in cells — **bold**, `code`, [links](https://example.com) — is passed through untouched, so you can format cell text as usual. Block content such as lists or code fences cannot go inside a GFM table cell at all.

Everything runs in your browser; nothing you type or paste is uploaded. Use the Markdown preview tool to see the rendered table.
