Markdown Table Formatter
Paste a rough Markdown table and get it aligned with clean, consistent column widths.
Turn CSV data, tab-separated data, or a messily-aligned Markdown table into a properly formatted Markdown table with consistent column widths and pipe alignment. Handy for writing documentation, GitHub READMEs, or pull request descriptions where a hand-typed table quickly goes ragged. Also converts plain CSV or TSV directly into Markdown table syntax. Runs entirely client-side.
Runs on your device. This tool processes your file inside this browser tab. Nothing is uploaded, so it also works offline once the page has loaded, and closing the tab discards the file from memory.

Common questions
Do I need a separator row?
Yes - a standard Markdown table with a header, a `---` separator row, and data rows below.
Can I convert CSV directly to a Markdown table?
Yes - paste CSV or tab-separated data and it's formatted into proper Markdown table syntax.
Does it support column alignment (left/center/right)?
Standard Markdown alignment markers in the separator row (`:---`, `:---:`, `---:`) are preserved and applied.
Is my data uploaded anywhere?
No - parsing and formatting run entirely in your browser.
