Markdown Table Generator

Build Markdown tables visually — set rows and columns, type your data, choose alignment, and copy clean Markdown or preview the result instantly. No more counting pipes by hand.

How to Use

  1. Set the number of rows and columns
  2. Type your data into each cell
  3. Choose column alignment if needed
  4. Copy the generated Markdown table
  5. Copy the formatted or generated result directly to your clipboard.
  6. Use the result in your application, configuration, or documentation safely.

All processing is done in your browser, and files are never sent to a server.
