CSV/JSON to table

CSV/JSON to table is an API that turns data into a real, presentation-ready table: as a PDF or as an image. Give it a CSV or a JSON array, no HTML to write.

How it works

You send csv (the text) or data (an array), never both, and get back the table already built, with a highlighted header and alternating rows. Defaults to PDF; with format=png (or jpeg/webp), an image.

Coming from an Excel file? Use Excel to JSON first, and pass its result to this tool's data.

All you need

Your API key. Create it in your dashboard with "+ Create key".
In your automation platform, an "HTTP Request" step (n8n, Make, Zapier, Pipedream…).
