About This Tool

Transform between JSON and XML formats with our intelligent, free online converter. Key features include:

  • Smart semantic tag conversion with automatic singularization/pluralization
  • Flexible attribute handling and preservation
  • Support for complex nested structures and arrays
  • Pretty printing with proper indentation
  • Customizable root element naming
  • Browser-based processing for data privacy

JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) are two fundamental data formats in modern development. While JSON is preferred for APIs and web services due to its simplicity, XML remains crucial for legacy systems, documentation, and specific industry standards.

Our converter bridges these formats intelligently, maintaining data structure and relationships while offering smart features like semantic tag conversion and attribute handling. Whether you're working with API responses, configuration files, or data migration, this tool ensures accurate and meaningful conversions.

How to Use

  1. Select your conversion direction (JSON → XML or XML → JSON)
  2. Enter your data or upload a file
  3. Configure conversion options:
    • Pretty Print: Format output with proper indentation
    • Use Attributes: Convert properties to XML attributes
    • Root Element: Set the main XML container element
    • Semantic Tags: Enable smart array item naming
  4. Watch the conversion happen in real-time
  5. Copy or download your converted data

Frequently Asked Questions

What is semantic tag conversion?

Semantic tag conversion intelligently transforms array items into meaningful XML tags. For example, an array of 'people' becomes individual 'person' tags, making your XML more readable and semantically correct.

How does attribute handling work?

Properties prefixed with underscore (_) in JSON are converted to XML attributes. For example, {_id: '123', name: 'John'} becomes John. When converting XML to JSON, attributes are preserved with underscore prefixes.

Can I convert complex nested structures?

Yes, our tool handles deeply nested objects and arrays while maintaining their structure. It also supports mixed content, attributes at any level, and preserves the relationship between elements.

What's the difference between XML attributes and elements?

XML attributes are metadata that go inside the opening tag (e.g., ), while elements are nested content (value). Our tool lets you choose how to represent your data using either or both.

Is there a size limit for conversion?

The tool processes data in your browser, so the practical limit depends on your device's capabilities. For optimal performance, we recommend keeping files under 5MB. For larger files, consider processing in chunks.
