What is this tool?

Builds GitHub-flavored Markdown tables. Paste comma- or tab-separated data (a spreadsheet copy-paste works — tabs are detected automatically, and quoted CSV cells are handled) with the first row as the header, or switch to the interactive builder and type into a grid. Pick left, center, or right column alignment; cells are padded so the raw Markdown stays readable, and pipe characters are escaped automatically.

How to use it

  1. Paste CSV/TSV data, or build the table cell by cell.
  2. Choose column alignment (left, center, right).
  3. Copy the generated Markdown table.
