Markdown Table Editor

Paste a markdown table on the left and edit the cells in a live grid on the right. Add or remove rows and columns, rename headers, change column alignment, transpose, reverse, or clear — the clean markdown table on the right updates on every keystroke. Pure client-side, no upload.

How it works

  • Click any cell to edit. The markdown table on the right updates on every keystroke.
  • Use + Row and + Column to grow the table; Clear rows empties the data rows but keeps the header.
  • Change a column’s alignment with the per-column align dropdown — left, right, centre, or default (auto-detect numeric columns).
  • Transpose swaps rows and columns (the original header becomes the first column).
  • The output is the source of truth: copy it anywhere a GFM reader accepts tables.
