Markdown Table Generator

Convert tab, comma, or pipe-separated data into GitHub-flavored Markdown tables with header and alignment options.

Tool workspace

The interactive tool requires JavaScript.

Instructions

1. Paste table data copied from a spreadsheet, CSV snippet, or delimited text.
2. Choose tab, comma, or pipe separation and select the header source.
3. Choose the alignment and whitespace behavior.
4. Generate the Markdown, review it, then copy it into your target editor.

Paste data from a spreadsheet, a small CSV snippet, or pipe-separated text, then choose the delimiter, header behavior, and alignment marker. Generation stays in your browser and returns Markdown text only without uploading the input.

The generator pads short rows, escapes cell pipes as \|, and supports default, left, center, or right alignment markers. It deliberately does not render an HTML preview.

GitHub-flavored Markdown tables

The output contains a header row, separator row, and body rows wrapped with pipes. Preview the result in the Markdown renderer where you plan to publish it.

Browser-local boundaries

The tool makes no network request. Use simple delimited input; complex CSV quoting belongs in a dedicated CSV parser.
