CSV → Markdown table API

Convert CSV (or TSV) to a GFM pipe table.

POST /api/v1/convert/csv-to-table turns CSV or TSV data into a clean GitHub-Flavored Markdown table. Handles quoted fields, embedded newlines, and locale-specific delimiters.

Overview

RFC-4180-compliant CSV parser. Quoted fields, embedded newlines, and escaped quotes are handled correctly. The first row becomes the table header.

Request

Authenticate with Authorization: Bearer YOUR_API_KEY and send a JSON body containing the parameters below. Pick your language:

curl -X POST 'https://trymarkdownviewer.com/api/v1/convert/csv-to-table' \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"csv":"name,age\nAda,36\nLinus,54"}'

Body parameters

Field	Type	Required	Description
csv	string	required	CSV/TSV source. Max 512 KiB.
delimiter	"," \| "\t"	optional	Field delimiter. Defaults to comma.

Response

Success responses are wrapped in a data field. Errors use { error: { code, message } } with an appropriate HTTP status — see the error reference.

    "markdown": "| name | age |\n| --- | --- |\n| Ada | 36 |\n| Linus | 54 |\n",
