XML to JSON Converter

What is XML to JSON Converter?

XML to JSON Converter is a powerful browser-based tool that transforms XML documents into JSON format instantly. Whether you're working with API responses, configuration files, or data feeds, this tool makes it easy to convert XML data into a clean, readable JSON structure without uploading files to any server.

Why Convert XML to JSON?

JSON has become the preferred data format for modern web applications and APIs due to its simplicity and lightweight nature. Converting XML to JSON unlocks several key advantages:

Your Data Stays Private

Security and privacy are built into the core of this tool. All processing happens entirely in your browser:

How to Use

Basic Conversion

Converting XML to JSON is straightforward and happens in real-time. Follow these simple steps:

Configure Attribute Handling

XML attributes can be represented in JSON in different ways. The converter gives you full control over how attributes are mapped to JSON keys. Use the Attr Prefix buttons in the toolbar to choose your preferred format:

{
  "book": {
    "@id": "123",
    "@category": "fiction",
    "title": "Example Book"
  }
}

{
  "book": {
    "_id": "123",
    "_category": "fiction",
    "title": "Example Book"
  }
}

{
  "book": {
    "id": "123",
    "category": "fiction",
    "title": "Example Book"
  }
}

Configure Text Node Key

When an XML element contains both text and child elements (mixed content), the text is stored with a configurable key. Choose the format that best matches your application's requirements:

• #text (default) — Text stored as "#text": "content"
• _text — Text stored as "_text": "content"
• value — Text stored as "value": "content"

Output Options

Customize how your JSON output is displayed and formatted:

Features

Real-Time Conversion

The converter processes your XML data as you type with a smart debounce mechanism. Paste or type XML on the left, and the JSON output updates automatically on the right — no need to click a convert button.

Flexible Attribute Handling

Choose how XML attributes are mapped to JSON keys with three options: @ prefix, _ prefix, or merge directly into the object. This flexibility lets you match the JSON structure expected by your application, whether you're working with specific API requirements or internal data standards.

Smart Element Grouping

When multiple XML elements share the same tag name (e.g., multiple <book> elements), they are automatically grouped into a JSON array. Single elements remain as objects. This intelligent handling ensures your JSON structure accurately represents the XML hierarchy without manual intervention.

<library>
  <book>Book 1</book>
  <book>Book 2</book>
  <book>Book 3</book>
</library>

{
  "library": {
    "book": [
      "Book 1",
      "Book 2",
      "Book 3"
    ]
  }
}

Interactive Tree View

Switch to the tree view to explore your JSON output visually. Each object and array node can be expanded or collapsed, with badges showing the number of keys or items. Color-coded values make it easy to distinguish strings, numbers, booleans, and null values.

File Support

Upload XML files directly from your device. The converter accepts .xml, .svg, .xhtml, and .rss file formats. Download the converted JSON as a .json file with one click.

• .xml — Standard XML documents
• .svg — Scalable Vector Graphics files
• .xhtml — XHTML documents
• .rss — RSS feed files

Validation and Error Reporting

Invalid XML is detected immediately with clear error messages. The status bar shows whether your XML is valid or invalid, along with detailed statistics including element count, attribute count, and output file size.
