How to Use

Copy a table from Excel or Google Sheets and paste it; the Markdown equivalent appears immediately. Pick the delimiter (tab, comma, semicolon, or pipe). The first row is treated as a header. Column alignment (left / center / right) is configurable.

How Markdown Tables Work

Standard Markdown doesn't include table syntax, but GitHub Flavored Markdown (GFM) standardized the `| col1 | col2 |` pipe form. The separator row (`| --- | --- |`) can include colons (`:---:` for center) to specify alignment. The tool turns each input row into a Markdown row and pads columns for visual alignment in the source.

Use Cases

  • Embedding an Excel table into a README or documentation
  • Converting a Notion or Slack table into Markdown
  • Pasting spreadsheet data into a GitHub Issue or PR
  • Repurposing meeting-note tables (Notion / Confluence) for a tech blog
  • Sanity-checking script-generated Markdown from CSV input

Privacy

Conversion happens entirely in the browser; input never leaves your device. Tables with internal or confidential data stay local.
