Convert CSV to Markdown

Convert CSV data into a clean, formatted Markdown table, entirely in your browser. Your data never leaves your device.

Converting CSV to a Markdown table turns spreadsheet-style comma-separated data into a clean GitHub-flavored Markdown table you can paste into a README, wiki, or document. iLoveMD does it entirely in your browser: paste CSV or open a .csv file, and it reads the rows and columns, treats the first row as the header, and escapes any characters that would break the table layout. Because the conversion runs locally in JavaScript, your data is never uploaded to a server, it works offline once the page has loaded, and there is no sign-up or tracking. Copy the table to your clipboard or download it as a .md file, ready for documentation or version control. For spreadsheets in Excel format, use the Excel to Markdown tool.

CSV to Markdown Table Docs

Convert any CSV (comma-separated values) into a clean, formatted Markdown table: header row + separator + body rows, column alignment automatic. Useful for embedding small datasets in Markdown documents without leaving plain text.

Format support

The parser handles the full RFC 4180 CSV spec:

  • Commas inside quoted fields, "Smith, John" stays one column.
  • Line breaks inside quoted fields, multi-line cell content stays in one cell.
  • Escaped quotes (""), properly unescaped.
  • Mixed line endings, \n, \r\n, and \r all work.

Output

The first row is always treated as the table header. A separator row (| --- | --- |) is inserted automatically below it so any Markdown renderer parses the output as a real table.

| Name      | Email             | Role      |
| --------- | ----------------- | --------- |
| Jane Doe  | jane@example.com  | Founder   |
| John Smith| john@example.com  | Engineer  |

Column widths in the output are padded so the source Markdown is readable in plain text too, not just when rendered.

Limitations

  • Very wide tables (50+ columns), render fine but become unwieldy in any Markdown view. Consider transposing or splitting.
  • Very long values inside cells: Markdown tables don't wrap natively; consumers (GitHub, Notion) handle this differently.
  • Delimiters other than comma, TSV (tab-separated) and semicolon-separated are NOT auto-detected. Convert your source to comma-separated first.

Privacy

Pure JavaScript parsing in your browser. No library load, no network call. Your spreadsheet data never leaves your device.

Frequently asked questions

Does my CSV get uploaded anywhere?

No. The conversion runs entirely in your browser. Your data never leaves your device.

Does it detect the header row?

Yes. The first row is treated as the table header, and a separator row is added automatically.

What about commas inside quoted fields?

Quoted fields are parsed correctly, so commas and line breaks inside quotes do not break the columns.

Does it work offline?

Once the page has loaded, yes. Conversions run locally without an internet connection.

Can it handle large spreadsheets?

Yes, within your browser's memory. Very large files may take a moment to render in the preview.
