The Free CSV to Markdown Converter That Just Works
Sometimes you have data in a spreadsheet or CSV file but you need a Markdown table: documenting an API in a README, adding a comparison table to a wiki, dropping data into a GitHub issue, or turning an export into portable plain-text notes. Our free online CSV to Markdown converter does exactly that: paste your CSV, get a clean pipe-delimited Markdown table, and copy or download it as a .md file. Everything runs locally in your browser, so your data is never uploaded and never logged.
Your CSV is never sent to our servers. All conversion happens in JavaScript on your device. We log nothing. Free forever with no account required.
Auto-Detect Delimiter
Not sure if your file is comma, semicolon, tab, or pipe separated? Leave the delimiter on Auto and the converter figures it out for you using a robust CSV parser. You can also force a specific delimiter if your data is ambiguous, which is handy for European CSV files that use semicolons or for tab-separated exports.
Header Row and Column Alignment
Choose whether the first row of your data is a header. When it is, those values become the bold column headings and a divider row is added automatically. When it is not, the converter generates neutral Column 1, Column 2 headings so the table is still valid GitHub-flavored Markdown. Pick left, center, or right column alignment and the divider row uses the correct colon markers.
Clean, Valid Markdown Tables
- Pipe escaping: any pipe characters inside cells are escaped so they do not break the table
- Line breaks in cells: converted to
<br>so multi-line values stay in one row - Ragged rows: short rows are padded and long rows are kept intact
- Readable output: columns are padded to equal width so the raw Markdown is easy to read
