JSON to CSV

JSON to CSV is an API that converts an array of JSON objects into a CSV, with columns taken from the first object's keys. It quotes only where needed (if a value contains a comma or a quote), not every field.

How it works

You send data (an array of objects, all the same shape) and get back the CSV text, ready to download or save.

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…).
