How to use
- Paste your CSV into the editor — the first row becomes the table header.
- The markdown table appears instantly with a --- alignment row under each column.
- Copy the table and paste it into your README, issue or docs page.
Frequently asked questions
Which markdown flavor is the output?
GitHub-flavored markdown pipe tables, the dialect used by GitHub, GitLab, Obsidian and most static site generators. The output is a header line, a --- alignment line and one line per data row.
What happens to a pipe character inside a cell?
It is escaped as \| so it renders as a literal pipe instead of splitting the cell into two columns. The column structure of your table stays intact no matter what the data contains.
How are line breaks inside a cell handled?
A multi-line quoted CSV cell cannot keep its raw line break inside a table row, so each break is converted to a <br> tag. GitHub and most renderers show it as a line break inside the cell, preserving the original layout.
Does it fix rows with missing or extra columns?
No — it refuses to guess. A row whose column count differs from the header stops the conversion with an explicit error, so a damaged export never silently becomes a misaligned table.
Is my data sent to a server?
No. The conversion runs entirely in your browser with local JavaScript. Nothing is uploaded, stored or logged, so internal data is safe to paste.

About this tool
This free online CSV to markdown table converter produces GitHub-flavored pipe tables ready to drop into a README, an issue comment, a pull request description or any documentation site. Paste spreadsheet data and the table appears instantly: the first CSV row becomes the header, a --- alignment row is generated for every column, and each data row becomes one pipe-delimited line. The two characters that break markdown tables are handled for you: a pipe character inside a cell is escaped as a backslash-pipe so the column structure survives, and a line break inside a multi-line cell becomes a <br> tag that GitHub and most markdown renderers display as a real line break. Standard CSV quoting is respected — commas, escaped quotes and embedded newlines inside quoted fields all survive the trip. If the input is broken, the tool says so instead of improvising: rows with the wrong column count or an unterminated quote are reported with a clear error. Everything runs locally in your browser; no data is uploaded. Copy the table straight out of the preview.
