JSON to XML
LiveConvert JSON data to well-formed XML documents with proper structure.
Understanding JSON (JavaScript Object Notation)
XML — Extensible Markup Language — remains the required data format for SOAP web services, RSS/Atom feeds, Android resource files, Maven/Gradle build configurations, and many enterprise integration platforms. When your data exists as JSON from a modern REST API but the consuming system requires XML, you need a converter that handles the structural differences between these two fundamentally different data representations.
Transform JSON data structures into well-formed XML documents with proper nesting and special character handling.
The Devkitr JSON to XML converter maps JSON objects to XML elements, arrays to repeated child elements, and primitive values to text content — handling naming rules (XML element names cannot start with numbers), special character escaping (&, <, >), and null value representation. The entire conversion runs in your browser, keeping API keys and sensitive data off external servers.
In a typical development workflow, JSON to XML becomes valuable whenever you need to convert json data to well-formed xml documents with proper structure. Whether you are working on a personal side project, maintaining production applications for a company, or collaborating with a distributed team across time zones, having a reliable browser-based conversion tool eliminates the need to install desktop software, write one-off scripts, or send data to third-party services that may log or retain your information. Since JSON to XML processes everything locally on your device, your data stays private and your workflow stays uninterrupted — open a browser tab, paste your input, get your result.
Key Features
Smart Element Naming
Handles JSON keys that conflict with XML naming rules by sanitizing element names — replacing leading digits, spaces, and special characters with valid alternatives.
Array-to-Element Mapping
Converts JSON arrays to repeated XML sibling elements with configurable wrapper and item element names, preserving the collection semantics.
Proper XML Escaping
Escapes reserved XML characters (&, <, >, ", ') in all output to produce well-formed XML that passes any XML parser validation.
Root Element Configuration
Lets you specify the root element name for the XML document rather than defaulting to a generic wrapper, producing cleaner output.
How to Use JSON to XML
Paste Source JSON
Copy the JSON object or array you want to convert and paste it into the input panel.
Set Root Element Name
Optionally specify the root XML element name — for example, "catalog", "users", or "response" — to match your target schema.
View Generated XML
The converter outputs well-formed, indented XML immediately. Review the element mapping to confirm it matches your expected structure.
Copy the XML
Copy the generated XML document to use in your SOAP request, configuration file, or integration platform.
Use Cases
SOAP Service Integration
Convert JSON payloads from a REST API into XML request bodies required by legacy SOAP web services in enterprise systems.
RSS/Atom Feed Generation
Transform JSON content data into XML-structured feeds for blog syndication, podcast distribution, or news aggregator compatibility.
Android Resource Files
Convert JSON-based localization data into Android strings.xml resource format for mobile app internationalization workflows.
Enterprise System Integration
Bridge modern microservices that use JSON with legacy enterprise platforms (SAP, Oracle) that consume XML-based data feeds.
Pro Tips
Understand that JSON and XML have different data models — JSON supports arrays natively while XML uses repeated elements, which affects how collections are represented.
Add an XML declaration (<?xml version="1.0"?>) manually if your target system requires it, as the converter focuses on the document body.
For complex mappings, consider using attributes for metadata and elements for data content to produce more idiomatic XML output.
Test converted XML against the target system's XSD schema if one exists, since the auto-generated structure may not match expected element ordering.
Common Pitfalls
Expecting the converter to produce valid XML from JSON with numeric keys
Fix: XML element names cannot start with digits. The converter sanitizes these, but rename numeric keys in your JSON to descriptive names for cleaner output.
Not specifying an appropriate root element name
Fix: Every XML document needs a single root element. Using a generic name like "root" works but makes the XML harder to understand — pick a meaningful name.
Ignoring character encoding differences
Fix: JSON uses UTF-8 Unicode. Ensure your target XML consumer also expects UTF-8, or add the encoding attribute to the XML declaration.
Frequently Asked Questions
QHow are JSON arrays handled in XML?
Array items are wrapped in repeating element tags using the parent key name as the element name.
QDoes it handle special characters?
Yes. Characters like <, >, &, and quotes are properly escaped as XML entities in the output.
QCan I customize the root element name?
The tool uses a default root element. You can edit the output to change the root tag as needed.
