Convert CSV to Markdown Tables

Paste CSV data or upload a .csv file, auto-detect the delimiter, and get a clean Markdown table. Copy or download instantly.

Your files never leave your browser. All processing happens locally.

How do you turn a CSV file into a Markdown table?

Converting CSV to a Markdown table reformats rows of comma-separated values into the pipe-and-dash syntax that GitHub, GitLab, and most documentation tools render as a clean table. It's the quickest way to move spreadsheet data into a README or .md doc.

Paste your CSV or upload a file and the tool auto-detects the delimiter (comma, semicolon, or tab), handles quoted fields and escaped quotes, and outputs GitHub Flavored Markdown you can copy in one click. Files up to 512 KB are supported, and all parsing runs locally in your browser — your data is never uploaded.
