JSON to XML Converter
Need to send data to a system that only speaks XML? This tool takes your JSON and generates properly formatted XML with correct indentation, an XML declaration, and safe element names. Arrays become repeated elements, nested objects become child elements, and special characters are properly escaped.
It's useful when you're integrating with older APIs, generating configuration files for Java applications, or creating test data for XML-based systems. The output is valid, well-formed XML that passes any standards-compliant parser.
How JSON Maps to XML
JSON objects become XML elements with child elements for each property. JSON arrays become repeated elements — each array item gets its own tag. Primitive values (strings, numbers, booleans) become text content within their parent element. Null values produce self-closing empty elements.
Element Naming
XML has stricter naming rules than JSON. Element names can't start with numbers, can't contain spaces, and have a limited character set. This converter automatically sanitizes JSON keys to produce valid XML element names — replacing invalid characters with underscores while keeping the names readable.
Special Character Escaping
XML has five characters that need escaping: &, <,>, ", and '. All string values are properly escaped in the output, so you won't get malformed XML even if your JSON contains HTML snippets or special characters.
Integration Scenarios
SOAP APIs: Building request bodies for legacy SOAP services that expect XML.Java Ecosystem: Spring configurations, Maven POMs, Hibernate mappings.Document Formats: XHTML, SVG, and other XML-based document formats.Data Exchange: Many B2B integrations still use XML (EDI, healthcare HL7, financial FIX).
Output Quality
The generated XML includes an XML declaration (<?xml version="1.0" encoding="UTF-8"?>), consistent 2-space indentation, and proper nesting. It's human-readable and machine-parseable. Copy it directly into your application, SOAP client, or testing tool — no cleanup needed.
