The XML to JSON Converter transforms XML documents into JSON format using the fast-xml-parser library, capable of parsing XML attributes (prefixed with @_), CDATA sections, comments, and namespaces. It generates pretty-printed JSON output for easier readability, supporting XML files up to several megabytes efficiently. Since the conversion runs entirely in your browser, no data is transmitted to external servers, preserving your privacy. For additional data handling, you might consider using Json To Xml to reverse the process or Xml Formatter to improve XML readability.

How to Use

  1. Paste or load your XML content into the input field.
  2. Optionally enable or disable attribute parsing to include or exclude XML attributes (prefixed with @_).
  3. Click the convert button to generate JSON output.
  4. View the pretty-printed JSON result in the output area.
  5. Copy or download the JSON for further use.

How It Works

This tool leverages the fast-xml-parser library, which parses XML strings into JavaScript objects by traversing the XML DOM structure. It captures XML attributes by prefixing them with @_ to differentiate from element nodes. CDATA sections and comments are also recognized and converted appropriately. Namespace handling ensures that elements and attributes with prefixes are preserved in the JSON output. The parser optionally ignores attributes to simplify the JSON structure when required. The final output is formatted using JSON pretty-printing with indentation for clarity.

Example

<note>
  <to>Alice</to>
  <from>Bob</from>
  <heading>Reminder</heading>
  <body>Meeting at 10 AM</body>
</note>

Converts to:

{
  "note": {
    "to": "Alice",
    "from": "Bob",
    "heading": "Reminder",
    "body": "Meeting at 10 AM"
  }
}

When to Use

  • Parsing SOAP API XML responses into JSON objects for easier manipulation in JavaScript.
  • Converting RSS or Atom XML feeds to JSON for web application consumption.
  • Extracting metadata from SVG XML files for frontend rendering or analysis.
  • Transforming configuration files in XML format to JSON for compatibility with modern frameworks.
  • Students learning data format conversions and XML structure parsing.

For formatting raw XML or JSON data before conversion, consider using Xml Formatter or Json Formatter.

Frequently Asked Questions

Does the XML to JSON Converter handle XML attributes?

Yes, the tool parses XML attributes and prefixes them with @_ in the JSON output. You can optionally ignore attributes if you prefer a cleaner JSON structure.

Can this converter process large XML files?

The converter uses the fast-xml-parser library optimized for performance and can handle XML files of several megabytes efficiently, depending on your browser's memory limits.

Are CDATA sections preserved in the JSON output?

CDATA sections are recognized and their content is included as string values within the JSON output, ensuring no data loss during conversion.

Is my XML data uploaded to any server during conversion?

No, all parsing and conversion occur locally in your browser using JavaScript, so your XML data is never uploaded or transmitted externally, maintaining privacy.

How does the tool handle XML namespaces?

XML namespaces and prefixed elements or attributes are preserved in the JSON output as part of the key names, allowing you to retain namespace distinctions.

Can I convert the JSON result back to XML?

Yes, you can use the related Json To Xml tool to reverse the process and convert JSON back to XML format.
