CSV to Markdown table: convert CSV into a GitHub table

$0.01 per call · failed calls are never charged · no account or API key needed

Convert CSV (comma, semicolon, tab or pipe, detected automatically; quoted fields supported) into a GitHub-flavoured Markdown table, with number columns right-aligned, pipes escaped and line breaks kept as <br>. Up to 100 KB. Use to show spreadsheet data in a README, chat reply, issue or report; for JSON use csv_to_json.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/csv/to-markdown?csv=tool%2Cprice%2Ccalls%0Aweather%2C0.01%2C120%0Asearch%2C0.01%2C45"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/csv/to-markdown?csv=tool%2Cprice%2Ccalls%0Aweather%2C0.01%2C120%0Asearch%2C0.01%2C45&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Example result

{
  "markdown": "| tool | price | calls |\n| --- | ---: | ---: |\n| weather | 0.01 | 120 |\n| search | 0.01 | 45 |",
  "rows": 2,
  "columns": 3
}
