Your file, as an API.

Drop in a spreadsheet. Explore its JSON. Publish when you’re ready.

Drop your file here

Excel, CSV or JSON. The preview runs in this browser.

Your data is ready for something bigger. Drop your file and see what your API could look like.

A LOOK INSIDE

From rows
to a response.

Turn the columns you already have into fields your app can read. The response on this page is an example. A published endpoint is a separate step.

GET /products EXAMPLE
[{
  "name": "Pocket notebook",
  "price": 8,
  "in_stock": true
}]

Before you upload

Where does my file go when I preview it?

It stays in this browser while you set up the project, including after a refresh. FileToAPI uploads the original file only after you review the project and create an account or sign in.

Do I need an account to try FileToAPI?

No. You can set up the file, endpoints, and plan in this browser without an account. An account is required to store the file, publish endpoints, or pay for a plan.

What happens if my file is too large for the free plan?

You can still preview it here when it is within the reading limit: 50 MB for CSV or JSON, 340.0 KB for .xlsx, and 422.5 KB for .xls. That limit is separate from hosting. Free stores a file up to 25 MB. A larger file can remain a preview. Importing it needs a plan that allows that size. Paying does not raise the reading limit.
