JSON to XML Converter
Convert JSON objects to XML format. Perfect for SOAP APIs, RSS feeds, legacy systems, and configuration files that require XML structure with full control over formatting and element naming.

XML Best Practices
- •Always include XML declaration for proper encoding specification
- •Use well-formed XML with single root element and properly closed tags
- •Escape special characters: &, <, >, ", ' using entity references
- •Use CDATA sections for large text blocks with special characters
- •Keep element names descriptive and use consistent naming conventions
JSON vs XML Trade-offs
- •XML is more verbose but self-documenting with schema validation (XSD)
- •JSON is compact and native to JavaScript, XML needs parsing
- •XML supports attributes, comments, and mixed content; JSON doesn't
- •XML has better tooling for enterprise systems (XSLT, XPath, XQuery)
- •Use JSON for modern APIs, XML for legacy systems and SOAP services
Pro Tips
- •Unwrap arrays creates multiple elements with same name (common in RSS/SOAP)
- •CDATA sections preserve formatting and special characters without escaping
- •Type attributes help preserve JSON type information for round-trip conversion
- •All conversion happens client-side - your data never leaves your browser

When to Use This Tool
Convert JSON data to XML for SOAP API requests. SOAP exclusively uses XML for message exchange. Generate properly formatted SOAP envelope bodies from JSON objects for legacy enterprise integrations.
Create RSS or Atom feed XML from JSON data structures. Perfect for generating podcast feeds, blog syndication, or news aggregators that require XML format with specific element structures.
Interface with older enterprise systems that only accept XML. Many banking, healthcare, and government systems require XML for data exchange due to established standards like HL7, ACORD, or EDIFACT.
Generate XML config files for applications like Spring, Maven, Ant, or .NET that use XML for configuration. Convert your JSON configs to XML when migrating between systems or frameworks.
Transform JSON data into XML for processing with XSLT stylesheets. XSLT is powerful for XML-to-HTML/PDF transformations in reporting and documentation systems.
Convert to XML for EDI (Electronic Data Interchange), SVG graphics data, or other XML-based formats like KML for maps, MusicXML for notation, or SCORM for e-learning content.
How It Works
Parse and validate JSON input
Check root and array element names are valid XML identifiers
Traverse JSON structure recursively
Convert objects to XML elements with child elements
Handle arrays based on unwrap setting (multiple elements vs container)
Escape special characters (&, <, >, ", ') or wrap in CDATA
Apply formatting (indentation, line breaks) if pretty print enabled
Add XML declaration if enabled
100% Private
Files never leave your device. All processing happens locally in your browser.

Frequently Asked Questions
What's the difference between unwrapped and wrapped arrays?
Unwrapped arrays create multiple elements with the same name (e.g., <item>1</item><item>2</item>). Wrapped arrays create a container element with item children (e.g., <array><item>1</item><item>2</item></array>). Unwrapped is common in RSS and SOAP, wrapped preserves array structure for round-trip conversion.
When should I use CDATA sections?
Use CDATA for large text blocks with HTML, code snippets, or special characters. CDATA preserves formatting and avoids escaping characters like <, >, &. For example: <![CDATA[<script>alert('test')</script>]]> keeps the HTML intact without escaping. Don't use CDATA for simple strings.
What are type attributes and when are they useful?
Type attributes add type="string|number|boolean|null|object|array" to each element. They preserve JSON type information, which is lost in plain XML (everything is text). Useful for round-trip JSON→XML→JSON conversion or when consumers need to know original types.
How are invalid XML element names handled?
JSON keys with spaces, special characters, or starting with numbers are automatically sanitized. Invalid characters become underscores, and names starting with numbers get an underscore prefix. For example, '123-key name' becomes '_123_key_name'. Manual validation warnings appear for custom root/array names.
Can I convert JSON arrays at the root level?
Yes, but the array will be wrapped in a root element. XML requires a single root element, so root-level JSON arrays like [1,2,3] become <root><item>1</item><item>2</item><item>3</item></root>. Use the 'unwrap arrays' option to control array element generation.
What's the difference between self-closing tags and empty tags?
Self-closing tags use <element/> for empty elements, while empty tags use <element></element>. Both are valid XML. Self-closing is more compact and common in XHTML. Some older XML parsers prefer explicit closing tags. Choose based on your target system requirements.
How do I convert XML back to JSON?
Use an XML to JSON converter tool (the reverse operation). Note that some information may be lost in conversion because XML and JSON have different features. XML attributes, comments, and processing instructions don't map directly to JSON. Use type attributes to preserve type information.
Is my data secure during conversion?
Absolutely! All conversion happens entirely in your browser using client-side JavaScript. Your JSON data never leaves your computer or gets sent to any server. The tool works completely offline after the page loads. No data is stored or transmitted.
