How to Convert JSON to XML Online

Transform structured JSON objects and datasets into XML documents in four simple steps:

Paste JSON Payload

Paste your JSON object or array into the left editor pane, or click "Sample" to load demonstration data.

Configure Root Tag

Specify your preferred root wrapper tag (e.g. <root> or <response>) and array item element name.

Generate XML

Click "Convert to XML" to validate JSON syntax, escape reserved characters, and produce formatted XML markup.

Copy or Download

Copy the formatted XML markup directly to your clipboard or download it as an .xml document with one click.

What is a JSON to XML Converter?

A JSON to XML Converter is an online utility that transforms structured JSON (JavaScript Object Notation) into Extensible Markup Language (XML) documents.

While modern web services and database systems communicate via JSON, many enterprise business platforms, banking networks, SOAP API endpoints, and government data portals strictly require data submitted in XML.

CodeCrate's browser-based converter provides a reliable bridge between modern JSON applications and legacy XML infrastructure by generating properly formatted element tags, escaping reserved XML entities, wrapping arrays in clean item nodes, and providing customizable root element encapsulation.

JSON to XML Conversion Example

Examine how key-value pairs and arrays serialize into well-formed XML elements:

Input: JSON Object JSON Input

{
  "invoice": {
    "id": "INV-2026-09",
    "customer": "Global Media Corp",
    "amount": 2450.00,
    "paid": true,
    "lineItems": [
      "Cloud Hosting",
      "CDN Bandwidth"
    ]
  }
}

Output: Formatted XML Document XML Output

<?xml version="1.0" encoding="UTF-8"?>
<invoice>
  <id>INV-2026-09</id>
  <customer>Global Media Corp</customer>
  <amount>2450</amount>
  <paid>true</paid>
  <lineItems>
    <item>Cloud Hosting</item>
    <item>CDN Bandwidth</item>
  </lineItems>
</invoice>

Key Features of CodeCrate JSON to XML Converter

Engineered for seamless enterprise system integration and compliant XML serialization:

Customizable Root & Item Nodes

Configure the exact root tag name and array element tags to match the precise XSD schema expectations of your receiving server.

Automatic Entity Escaping

Characters such as &, <, >, ", and ' are converted into standard XML entities without corrupting payloads.

Total Local Privacy

Executed purely in browser memory. Sensitive customer records, billing details, and API responses never leave your device.

Common Developer Use Cases

Typical integration scenarios requiring JSON to XML translation:

1. SOAP Web Service Payloads

Convert modern application JSON objects into SOAP XML envelopes and bodies for integration with enterprise Java and .NET backends.

2. ERP & Banking Feeds

Transform JSON transaction outputs into XML formats required by SAP, Oracle NetSuite, and financial clearinghouse gateways.

3. Sitemap & RSS Generation

Convert JSON list objects containing URLs and post dates into valid XML sitemaps or RSS 2.0 channel feeds for search engines.

4. Configuration File Migration

Migrate modern JSON application settings into XML configuration files for older software frameworks like Spring XML or Android manifest files.

Data Format Considerations: JSON vs XML

Keep these technical considerations in mind when generating XML from JSON:

Valid Tag Identifiers: XML element names must not contain spaces or start with numbers. The converter sanitizes invalid characters automatically with underscores.
Root Element Enclosure: Unlike JSON which can be a naked top-level array, XML strictly mandates a single root tag enclosing all content.
No Native Booleans: XML treats all node content as text. Booleans and numbers are rendered as literal text nodes (e.g. <active>true</active>) for the receiver's schema validator.

Frequently Asked Questions

Answers to common questions regarding XML tags, array wrapping, and escaping.

Why does XML require a single root element?

The W3C XML standard mandates that every well-formed XML document must contain exactly one root tag that encapsulates all other elements. You can customize this root tag name in our options toolbar.

How does the converter handle JSON arrays?

JSON arrays are transformed into repeated sibling XML tags. For top-level arrays, each item is enclosed inside a customizable element within the root wrapper.

How are special characters escaped in XML?

Reserved XML characters like ampersands (&), angle brackets (< and >), and quotation marks are automatically escaped into standard XML character entities.

Is my data uploaded to any remote server?

No. All JSON validation, serialization, and XML indentation happen 100% locally in your browser memory. No data is ever transmitted across the internet.

Can I include or omit the XML declaration header?

Yes. The options bar includes a checkbox to toggle the declaration header depending on whether you need a standalone file or a fragment.

Can I download the generated XML document?

Yes. You can copy the XML output directly to your clipboard or download it as a ready-to-use .xml document with a single click.
