What this tool does

This Markdown table formatter makes tables readable in source form and more reliable in GitHub, documentation, notes, and static-site Markdown files.

Processing logic: split rows by pipe characters, normalize cell counts, calculate column widths, rebuild separator rows, and apply selected alignment.

Tables with escaped pipes inside cells may need manual review after formatting.

Example

Try the sample input, run format table, and compare the before-and-after structure in the result panel.

Use cases

  • Clean code before review or sharing.
  • Prepare structured text for documentation, snippets, or production workflows.
  • Check size, line count, structure, and quality before exporting.

Tips for better output

  • Keep the first row as the header.
  • Avoid unescaped pipe characters inside cell text.
  • Use short column names for better source readability.
