XML Formatter & Converter

Our formatting tool allows a smooth data transfer between other systems and forms the basis of other tools, such as XML to JSON converters, which utilise the consistent tag structure and location of attributes to correctly transform XML to the structure of a JSON object.

What is XML Formatting?

XML formatting: The logical organization of data based on the rules of the Extensible Markup Language (XML) (opening and closing tags, nested elements, attributes, and a single root element) to form a hierarchical, self-describing document. XML formatting is used to make sure the data is well-formed (all tags are closed correctly, all attributes are quoted, case-sensitive integrity, and usually the data is indented and has line breaks) and is still human readable, yet the structure can be reliably read by a machine. Note: Turn your JSON into C# code , explore our tools, and fix it fast!

Why Convert XML to JSON?

🌐 Lightweight and Web-Native

JSON is smaller, can be more quickly processed and is supported by JavaScript formally, which is why it is best suited to use in web applications and REST APIs.

⚙️ Streamlined Data Processing

It operate on arrays, objects and key-value pairs rather than long and unwieldy XML nodes and attributes.

🔗 Fluent Interoperability

Feed JSON straight into MongoDB, Node.js services, React components, or any recent data pipeline.

🚀 Faster Performance and Bandwidth

JSON has a compact syntax that can help decrease payload size (by up to 30 per cent over XML) to speed up API responses and reduce the cost of data transfer to mobile and web apps.

How It Works

📥 Enter your XML code

Paste any XML data, be it an API response, a configuration file or a database export. Copy it and paste it in the input box of the converter. It can take minified or pretty-printed XML, and you can clear or Load Sample to have a sample.

🔄 Click on the Convert Button

Press the convert button. The tool checks your XML to be well-formed at first - it ensures that there are matching tags, one root element, and attributes are quoted correctly. On passing validation, the XML tree is recursively converted to JSON, elements to objects, attributes to prefixed properties and repeated sibling elements to arrays.

📋 Copy Output

Once it has been converted, the JSON will be displayed in the output area neatly indented to be readable. To instantaneously grab it, click the “Copy to Clipboard” button. You also have options of pretty-printing or minifying output, or settings to flatten attributes or make arrays single-item.

🚀 Directly Insert It into Your Code, API or Database.

The JSON is prepared to be read and merged - no additional cleaning needed. The converted output is immediately operable whether you are developing a web application or testing your API or analysing data.

Example

❌ XML

<user><name>Dev</name></user>

✅ JSON

{
  "user": {
    "name": "Dev"
  }
}

Frequently Asked Questions

Is it compatible with big XML files?

Yes, it supports files as large as several MB in your browser. Streaming or batch processing is recommended with large files.

Is it possible to transform the JSON into XML?

No direct tool within this specific tool, but we do offer a separate JSON to XML converter if needed.

How are XML namespaces handled when converting to JSON?

Namespaces are maintained as xmlns attributes in the JSON output, or can be stripped with the options panel.

Is my data safe?

Absolutely, the converter is 100% client-side - your XML does not leave your computer.
