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.

FAQ

Can I paste a table copied directly from Excel or Google Sheets?

Yes. Spreadsheet cells are copied as tab-separated values, so choose the Tab delimiter and paste — the Markdown table appears immediately. The first row is treated as the header.

Which input delimiters are supported?

Tab (the default for Excel/Sheets pastes), comma (CSV), semicolon, and pipe. Pick the one that matches your source data.

How do I align columns left, center, or right?

Use the column alignment option. It writes colons into the GFM separator row (`:---` left, `:---:` center, `---:` right) so the resulting table renders with that alignment on GitHub and other GFM renderers.

Is it safe to paste internal or confidential spreadsheet data?

Yes. Conversion runs entirely in your browser — nothing is uploaded, logged, or stored — so tables containing internal or confidential data never leave your device.

Will the output render anywhere Markdown is accepted?

It produces GitHub-Flavored Markdown table syntax, which works in GitHub/GitLab issues and PRs, many static-site generators, and most GFM-compatible renderers. Plain CommonMark without table support won't render it as a table.
