Is my CSV uploaded anywhere?

No. Parsing and rendering happen entirely in your browser, so your spreadsheet data stays on your device and is never sent over the network.

Which row becomes the table header?

The first row of your CSV is treated as the header, and the remaining rows fill the body of a GitHub-flavored Markdown table.

What happens to pipe characters and line breaks in cells?

Pipe characters inside cells are escaped so they do not break the table layout, and newlines within a cell are flattened onto a single line.

Why convert CSV to a Markdown table?

Pasting raw CSV into a README or pull request looks messy, while a clean Markdown table reads well everywhere GitHub-flavored Markdown is supported. Drop your CSV above and get a properly aligned table you can copy straight into your docs.

How it works

The converter parses your CSV in the browser, taking the first row as the header and the rest as data rows, then renders a GitHub-flavored Markdown table. Pipe characters in cells are escaped to keep columns intact, and any newlines inside a cell are flattened so each record stays on one row. Because it all runs locally, none of your data is ever uploaded.
