Where Markdown tables render

GitHub, GitLab, Notion, Obsidian, most wikis and documentation generators render pipe tables. LLMs also read them reliably, which makes them a good format for giving tabular data to ChatGPT or Claude.

Large files

Huge tables are hard to read in Markdown. Filter the rows you need first, or keep CSV for data and use Markdown for summaries.

How to use

  1. Drop your file in the box above, or click to pick it.
  2. Wait a few seconds while it converts locally.
  3. Copy the result or download it.

FAQ

Are pipes in cells escaped?

Yes, | inside a cell becomes \| so the table does not break.

Semicolon-separated CSV?

Yes, the parser detects common delimiters.
