Overview
JSON 2 JSONP is a free, no-auth service that acts as a JSONP proxy, converting any JSON endpoint into a JSONP response on the fly to bypass browser cross-domain restrictions in legacy applications. It is particularly useful when working with older JavaScript environments that cannot use CORS. Simply pass your target JSON URL and a callback name to get a JSONP-wrapped response.
Beginner Tip
JSONP is a legacy technique mostly used for older browsers or environments without CORS support. If you are building a modern application, use a server-side proxy or an API that supports CORS instead, as JSONP has security limitations.
Available Data
The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.
Example Response
Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.
{
"status": "success",
"data": {
"result": "Data from JSON 2 JSONP",
"description": "Convert JSON to JSONP (on-the-fly) for easy cross-domain data requests using client-side JavaScript",
"timestamp": "2025-01-15T10:00:00Z"
}
} Field Reference
(JSONP response) The response is a JavaScript function call like myFunction({...}) wrapping the original JSON data from the target URL Implementation Example
Request skeleton. The URL below is this API's documentation page, not a live endpoint — swap in the path you need from the provider's docs before running it.
const url = "https://json2jsonp.com/";
const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data); What Can You Build?
