JSON to XML Converter

What is JSON to XML Converter?

JSON to XML Converter is a free online tool that transforms JSON (JavaScript Object Notation) data into XML (Extensible Markup Language) format. It maps JSON objects, arrays, and values to equivalent XML elements and structures, enabling data exchange with systems that require XML.

Why Would You Need to Convert JSON to XML?

• Legacy System Integration: Send data to older systems, SOAP services, or enterprise applications that require XML
• Document Generation: Create XML documents for reporting, invoicing, or regulatory compliance
• Data Exchange: Communicate with partners or APIs that only accept XML format
• Configuration Files: Generate XML configuration files from JSON data sources
• Cross-platform Compatibility: Ensure data works with XML-based tools and workflows

How to Convert JSON to XML - Step by Step

1. Input Your JSON: Paste your JSON data or upload a JSON file
2. Configure Options: Set root element name and attribute handling preferences
3. Click Convert: Press the convert button to generate XML output
4. Export Result: Copy the XML or download it as an .xml file

Key Features

• Custom Root Element: Specify the name of the root XML element
• Array Handling: Converts JSON arrays to repeated XML elements with configurable wrapper
• Pretty Formatting: Generates well-indented, human-readable XML output
• Special Character Encoding: Properly escapes XML special characters in values
• Null Value Handling: Configure how JSON null values are represented in XML

Tips for Best Results

• Use descriptive JSON keys that make sense as XML element names (avoid starting with numbers)
• Remember that JSON arrays become repeated elements - consider if you need a wrapper element
• Validate the output XML if your target system has strict schema requirements

Frequently Asked Questions

How are JSON arrays converted to XML?

JSON arrays are converted to repeated XML elements. For example, an array "items": [1, 2, 3] becomes multiple "item" elements. You can customize the element name and optionally add a wrapper element.

What happens to JSON keys with special characters?

XML element names have restrictions (no spaces, cannot start with numbers). Keys that violate these rules are automatically sanitized or you'll be prompted to provide valid element names.

Can I add XML namespaces to the output?

Yes, you can specify a default namespace and prefix in the advanced options. This is useful when the target system expects namespaced XML documents.
