Quickstart
Preview a file, save it, import it, and call one real GET.
Updated November 10, 2026
These steps work on the current app. A block marked Example on the homepage is an illustration. The curl command shown after you publish is a real request.
1. Preview without an account
Open the homepage. Choose a CSV, Excel, or JSON file, or use a sample. You will see a few rows as JSON. Set a filter, hide a column, or rename a JSON key. Nothing is uploaded yet.
2. Create a free account
Continue when you want to keep the preview. Registration does not ask for a card. In the same browser, the file name, size, field settings, filter, and up to five sample rows are saved to the account. The page says Preview saved. Choose the original file again when you want every row.
3. Import on Free when the file fits
If the file is within the Free per-file and storage limits, import it. The status then says File imported and shows the row count. A file over the limit can remain a preview. The page names the size, the Free limit, and the cheapest plan that can store it.
4. Publish one endpoint
On the file, name the endpoint, choose the visible fields and JSON keys, the writable fields, a filter if you want one, and the methods. Publish. Free includes one published endpoint. You get a URL, an access key, and a curl command.
5. Call it
Run that curl command. The response omits hidden fields. The request appears under Usage. A second publish on Free stops at the endpoint limit.
