Table to Markdown Converter

Turn a table you already have — an HTML <table>, a comma-separated CSV export, or a tab-separated block copied straight from a spreadsheet — into a clean, GitHub-Flavored Markdown table. Paste your data, pick the input format, and the Markdown appears instantly, ready to drop into a README, a pull request, an issue, or any Markdown-aware editor.

How to use it

1. Choose the Input Format that matches your data: HTML Table, CSV, or TSV.
2. Paste the table into the input box. If you copy a range of cells from Excel, Google Sheets, or Numbers, it arrives as TSV (tab-separated) — pick that option.
3. Adjust the options and copy the Markdown from the output panel.

The conversion runs entirely in your browser. Nothing you paste is uploaded to a server.

Options

• First Row as Header — treats the first row as the table header (the bold top row above the --- divider). Turn it off and the tool generates generic Column 1, Column 2, … headers, since a Markdown table always needs a header row.
• Column Alignment — sets the alignment marker in the separator row for every column: left (---), center (:-:), or right (--:). Markdown renderers use these to align the cell text.
• Compact Mode — outputs the smallest valid table (no padding spaces). Leave it off and columns are padded so the raw Markdown lines up in a monospace editor and stays readable before it's rendered.

What it handles for you

• Pipe escaping. A literal | inside a cell would otherwise split it into two columns, so every pipe in your data is escaped to \| automatically.
• Ragged rows. If some rows have fewer cells than others, the shorter rows are padded with empty cells so the table stays rectangular and valid.
• Messy HTML. The HTML parser reads <tr>, <th>, and <td> tags, strips any inline markup inside cells, and decodes common entities like & and  .

Which format should I pick?

If you copied cells directly from a spreadsheet, use TSV — that's the format the clipboard uses. If you exported a .csv file, use CSV (it understands quoted fields containing commas). If you're pulling a table out of a web page's source, use HTML Table.

Does it produce GitHub-Flavored Markdown?

Yes. The output is a standard GFM pipe table — the same syntax GitHub, GitLab, and most Markdown editors render as a table.

Is my data private?

Yes. The conversion happens locally in your browser; the table text never leaves your device.
