xml-to-json

Convert an XML file to JSON format. Auto-unwraps <root> and <root><item> wrappers for clean output. XML attributes are represented as @attr keys and text content as #text.

Endpoint

POST /v1/convert/xml-to-json

Content-Type: multipart/form-data

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

Output format: .json (application/json)

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

Conversion Rules

Simple XML -- auto-unwraps <root>: xml <root><name>Alice</name><age>30</age></root> Becomes: json {"name": "Alice", "age": "30"}
Repeated elements become a JSON array (auto-unwraps <root> and <item>): xml <root><item><id>1</id></item><item><id>2</id></item></root> Becomes: json [{"id": "1"}, {"id": "2"}]
XML attributes are prefixed with @: xml <user id="1" role="admin">Alice</user> Becomes: json {"@id": "1", "@role": "admin", "#text": "Alice"}

Output is pretty-printed JSON with 2-space indentation and unicode preserved. Repeated sibling elements with the same tag name become a JSON array automatically.

Code Examples

Python

import requests

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

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

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

Node.js

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

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

const json = await response.json();

PHP

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

Go

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

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