How to Convert XML to JSON — Step-by-Step Guide

Paste your XML above and get properly structured JSON instantly. Handles attributes, namespaces, SOAP responses, and nested structures — all in your browser.

Step 1

Input Your XML Data

Start by entering your XML data — from SOAP web services, enterprise systems, configuration files, or data exports. Three ways to get it in:

•

Paste XML: Copy XML from your application, SOAP API, or config file and paste directly

•

Upload a file: .xml

•

Load a sample: Click "Sample" to see a live example of XML to JSON conversion

•

Validate first: XML validator if you're unsure it's well-formed

Example: XML Input

A typical XML structure with attributes and nested elements:

<?xml version="1.0" encoding="UTF-8"?>
<products>
  <product id="1" category="electronics">
    <name>Laptop Pro</name>
    <price currency="USD">1299.99</price>
    <specs>
      <cpu>Intel i7</cpu>
      <ram>16GB</ram>
    </specs>
  </product>
  <product id="2" category="electronics">
    <name>Smartphone X</name>
    <price currency="USD">899.99</price>
  </product>
</products>

Step 2

Configure Conversion Options

Control how XML features map to JSON structures. The defaults work for most cases, but these options let you handle edge cases:

•

Attribute handling: XML attributes (like id="1") become JSON keys with an @ prefix ("@id": "1"). This keeps them distinct from child elements.

•

Text node key: When an element has both attributes and text content, the text goes into a #text key by default. Configurable.

•

Array detection: Repeating sibling elements (like multiple <product> tags) are automatically converted to JSON arrays.

•

Namespace handling: Strip or preserve XML namespace prefixes. Stripping is useful for SOAP responses where namespaces add noise.

•

Pretty print: Output formatted JSON with proper indentation for readability, or compact JSON for use in APIs.

Example: Converted JSON Output

The XML above, converted to structured JSON:

{
  "products": {
    "product": [
      {
        "@id": "1",
        "@category": "electronics",
        "name": "Laptop Pro",
        "price": {
          "@currency": "USD",
          "#text": 1299.99
        },
        "specs": {
          "cpu": "Intel i7",
          "ram": "16GB"
        }
      },
      { ... }
    ]
  }
}

Step 3

Copy or Download JSON

Get your JSON and use it immediately:

•

Copy to clipboard: One-click copy for immediate use in your code editor, REST API testing, or Postman

•

Download as JSON: Save as a .json file for storage, version control, or sharing

•

Keep working: JSON table, JSON formatter, or validate with the JSON validator

What is XML to JSON Conversion?

XML (Extensible Markup Language) and JSON (JavaScript Object Notation) are both widely used data interchange formats, but they have very different structures. XML uses opening and closing tags with optional attributes — familiar if you've worked with HTML, SOAP web services, or enterprise integration systems. JSON uses key-value pairs and arrays, making it the standard for modern REST APIs and JavaScript applications.

Converting XML to JSON is one of the most common tasks when modernizing legacy systems, integrating with third-party SOAP APIs, or migrating data to NoSQL databases like MongoDB. The challenge is that XML concepts like attributes, text nodes, namespaces, and processing instructions don't have direct equivalents in JSON — so conversion requires careful decisions about how to represent them.

This tool handles all of those decisions automatically with sensible defaults (attributes become @key properties, text nodes become #text, repeating elements become arrays) while giving you the flexibility to configure output to match your exact requirements.

XML vs JSON: Key Differences

Understanding the differences between XML and JSON helps you know when to convert and what to expect from the output. Here is a direct comparison across the most important dimensions:

Feature	XML	JSON
Syntax	Tags: <name>value</name>	Key-value: "name": "value"
Verbosity	Verbose — opening and closing tags for every field	Compact — no closing tags needed
Attributes	Native support: <item id="1">	No equivalent — attributes become keys
Arrays	Repeating elements (implicit)	Explicit array syntax: [ ]
Comments	Supported: <!-- comment -->	Not supported in standard JSON
Namespaces	Built-in namespace support	No native namespace support
Data types	Everything is a string by default	String, number, boolean, null, array, object
Best for	SOAP APIs, documents, configuration, enterprise systems	REST APIs, web applications, NoSQL databases
Parsing speed	Slower — more complex parsing rules	Faster — native in JavaScript (JSON.parse())
File size	Larger due to tag overhead	30–50% smaller than equivalent XML

XML — 312 characters

<user>
  <id>42</id>
  <name>Alice Johnson</name>
  <email>[email protected]</email>
  <role type="admin">
    <permissions>
      <permission>read</permission>
      <permission>write</permission>
    </permissions>
  </role>
  <active>true</active>
</user>

JSON — 198 characters

{
  "user": {
    "id": 42,
    "name": "Alice Johnson",
    "email": "[email protected]",
    "role": {
      "@type": "admin",
      "permissions": ["read", "write"]
    },
    "active": true
  }
}

When Do You Need to Convert XML to JSON?

XML to JSON conversion comes up constantly in real-world development. Here are the most common scenarios:

SOAP to REST Migration

Older enterprise systems expose data via SOAP APIs that return XML. When building modern REST frontends or mobile apps, you need JSON. Convert SOAP responses automatically and build a REST wrapper around legacy services.

Data Migration to NoSQL

Migrating from relational databases with XML columns or XML data exports to MongoDB, DynamoDB, or Firestore? These databases store JSON documents. Convert your XML exports to JSON as a first step.

RSS and Atom Feeds

RSS and Atom feeds are XML. If you're building a news aggregator, content dashboard, or feed reader in JavaScript, convert the XML feed to JSON to work with it natively using JSON.parse().

Configuration File Conversion

Many tools (Maven, Spring, Ant, log4j) use XML configuration files. When migrating to modern toolchains that prefer JSON or YAML configs, convert your XML configuration as a starting point.

E-Commerce Product Feeds

Product feeds from suppliers, marketplaces, and ERPs are commonly delivered as XML (Google Shopping, Amazon MWS). Convert them to JSON for use in headless commerce platforms and custom storefronts.

Government and Healthcare Data

Many public data APIs (HL7 FHIR, government open data portals) still publish in XML. Converting to JSON makes this data accessible to modern analytics pipelines, dashboards, and JavaScript-based data visualization tools.

Frequently Asked Questions

How are XML attributes handled in JSON conversion?

XML attributes are converted to JSON properties with an @ prefix — so id="1" becomes "@id": "1". This keeps them clearly distinct from child element content. You can configure the tool to merge attributes or use a custom prefix if your target system expects a different convention.

Can the tool convert SOAP XML responses to JSON?

Yes. Paste your SOAP response body directly — the converter handles SOAP envelope, header, and body elements. Enable "strip namespaces" to remove the soap: and schema namespace prefixes for cleaner output that's easier to work with in JavaScript.

Does it detect repeating XML elements as JSON arrays?

Yes. Repeating sibling elements with the same tag name are automatically converted to a JSON array. So three <product> elements become a "product": [...] array. You can also force a field to always be an array even when only one element is present.

Is the converted JSON compatible with REST APIs and JavaScript frameworks?

Yes. The generated JSON is standard and works with Node.js, React, Angular, Vue, and any REST API. You can also visualize the JSON in table format for easier analysis.

How does the tool handle XML namespaces?

Namespaces are preserved by default. Enable "strip namespaces" to remove them for cleaner JSON output — useful when integrating with SOAP services or microservices where the namespace information is not needed downstream.

What is the difference between XML and JSON?

XML uses opening and closing tags and supports attributes, making it verbose but expressive for document-oriented data. JSON uses key-value pairs and arrays, making it compact and native to JavaScript. JSON is 30–50% smaller than equivalent XML and parses significantly faster in browsers. See the full comparison table above.

Is there a file size limit?

No limits. Convert XML files of any size completely free. All processing runs in your browser — your data never leaves your machine. For very large files, use the file upload option rather than pasting to avoid browser clipboard limits.
