Markdown Table Generator — CSV & Excel to Markdown, Free

About Markdown Table Generator

Markdown tables are simple to read but tedious to type, with their rows of pipes and the dashed separator line under the header. If your data already lives in a spreadsheet or a CSV file, retyping it as Markdown is wasted effort. This tool bridges the two: paste comma-separated or tab-separated data straight from Excel, Google Sheets, or a CSV export, and it produces a clean GitHub-Flavored Markdown table ready to drop into a README, a wiki, an issue, or a chat message.

Delimiter handling is automatic by default. The Auto setting inspects your pasted data and figures out whether the columns are separated by commas or tabs, which means copying a range directly out of a spreadsheet (where cells are tab-separated) just works. If detection ever guesses wrong, you can force Comma or Tab explicitly. The tool also escapes any pipe characters inside your cells as backslash-pipe, so values containing a pipe do not break the table's column structure.

You can set column alignment to Left, Center, or Right, which the tool writes into the Markdown separator row using the colon syntax that GitHub-Flavored Markdown understands. The result appears in a monospace panel, formatted with the header row, the alignment separator, and each data row, and a Copy button puts the finished Markdown on your clipboard. Because the output is plain GitHub-Flavored Markdown, it renders correctly on GitHub, Notion, Reddit, Slack, and most other Markdown surfaces.

Developers documenting APIs, technical writers building wikis, and anyone posting tabular data in an issue or forum thread can save real time here. The conversion happens entirely in your browser, so spreadsheet data you paste is processed locally and never uploaded.
