json-to-xml

Convert a JSON file to XML format. Arrays are wrapped in <root><item> elements, objects become direct children of <root>, and scalar values are wrapped in <root><value>.

Endpoint

POST /v1/convert/json-to-xml

Content-Type: multipart/form-data

Accepted input: .json files (UTF-8 encoded)

Output format: .xml (application/xml)

Authentication

Requires either a private API key or a JWT token from a public key.

X-API-Key: sk_live_your_private_key

Or:

Authorization: Bearer <jwt_token>

Request Parameters

Parameter	Type	Required	Default	Description
`file`	file	Yes	--	The `.json` file to convert. Must be UTF-8 encoded.
`output_filename`	`string`	No	Input filename	Custom output filename. The `.xml` extension is added automatically.
`direct_download`	`boolean`	No	`true`	When `true`, returns raw XML bytes. When `false`, returns JSON metadata with a presigned download URL.

Conversion Rules

JSON object {"name": "Alice", "age": 30} becomes: xml <root> <name>Alice</name> <age>30</age> </root>
JSON array [{"id": 1}, {"id": 2}] becomes: xml <root> <item> <id>1</id> </item> <item> <id>2</id> </item> </root>
Scalar value "hello" becomes: xml <root> <value>hello</value> </root>

The root element is always <root>. Output is pretty-printed with single-space indentation.

Direct Download (`direct_download=true`, default)

HTTP 200 OK
Content-Type: application/xml
Content-Disposition: inline; filename="data_20260405_123456789.xml"

Code Examples

Python

import requests

with open("data.json", "rb") as f:
    response = requests.post(
        "https://api.enconvert.com/v1/convert/json-to-xml",

        files={"file": ("data.json", f, "application/json")}
    )

with open("data.xml", "wb") as out:
    out.write(response.content)

Node.js

const form = new FormData();
form.append("file", fs.createReadStream("data.json"));

const response = await fetch("https://api.enconvert.com/v1/convert/json-to-xml", {
    method: "POST",
    headers: { "X-API-Key": "sk_live_your_private_key" },
    body: form
});

const xml = await response.text();

PHP

$ch = curl_init("https://api.enconvert.com/v1/convert/json-to-xml");
curl_setopt_array($ch, [
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => ["X-API-Key: sk_live_your_private_key"],
    CURLOPT_POSTFIELDS => ["file" => new CURLFile("data.json", "application/json")]
]);
$xml = curl_exec($ch);
curl_close($ch);
file_put_contents("data.xml", $xml);

Go

body := &bytes.Buffer{}
writer := multipart.NewWriter(body)
part, _ := writer.CreateFormFile("file", "data.json")
file, _ := os.Open("data.json")
io.Copy(part, file)

req.Header.Set("Content-Type", writer.FormDataContentType())
req.Header.Set("X-API-Key", "sk_live_your_private_key")
resp, _ := http.DefaultClient.Do(req)
