Chuyển đổi bảng CSV ⇄ Markdown

This tool converts CSV data into a clean Markdown table you can drop into READMEs, issues, wikis and documentation, and converts Markdown tables back into CSV. The first row becomes the header, and you can set the column alignment.

Writing Markdown tables by hand is fiddly: every row needs the right number of pipes and the alignment divider has to line up. Pasting CSV and getting a correct table back removes all of that busywork.

Everything is processed locally in your browser; nothing you paste leaves your device.

It reads standard CSV with comma, semicolon or tab delimiters and handles quoted fields, so data exported from a spreadsheet converts without breaking on commas inside values.

The output is a GitHub-Flavored Markdown table: a header row, an alignment divider, then the data rows. It renders in GitHub, GitLab, most wikis and Markdown editors.

Alignment is written into the divider row using colons, :--- for left, :---: for center and ---: for right, which Markdown renderers use to align each column. Pipe characters in the data are escaped and line breaks inside cells are flattened so the table always stays valid.
