What is JSON to XML?
JSON dominates modern web APIs (REST, GraphQL); XML still powers enterprise systems (SOAP web services, financial protocols, government standards, Android/Java configs). Converting JSON → XML is needed for integration scenarios where one side speaks JSON and the other requires XML.
Common scenarios: SOAP integration (legacy enterprise APIs), Android manifest generation, Maven / Gradle build files, RSS / Atom feed creation, SVG generation from data, OFX/HL7 medical/financial standards, plist files (iOS/macOS configurations).
Conversion example
# JSON
{
"user": {
"name": "Alice",
"age": 30,
"hobbies": ["reading", "coding"]
}
}
# XML
<?xml version="1.0" encoding="UTF-8"?>
<root>
<user>
<name>Alice</name>
<age>30</age>
<hobbies>reading</hobbies>
<hobbies>coding</hobbies>
</user>
</root>JSON vs XML — historical context
- XML (1998) dominated APIs in the early-to-mid 2000s — SOAP, RSS, AJAX (X = XML originally)
- JSON rose in the late 2000s — simpler syntax, native to JavaScript, less verbose
- 2010+: most new public APIs are JSON; XML survives in enterprise/government/legacy
- 2026: ~95% of web APIs are JSON. XML is reserved for specific domains (SOAP, RSS, configuration formats, document standards like DOCX/ODT internally)
Conversion challenges
- JSON has no element name — XML needs a root element name (this tool uses
<root>) - JSON arrays become repeated XML elements with the same tag
- JSON keys become XML element names — must be valid XML (no spaces, no leading numbers)
- XML attributes vs elements — JSON has no attribute concept; conversion produces elements only
- Special characters —
<,>,&must be escaped as<, etc.
How to Use
- Paste JSON data, or upload a
.jsonfile. - Click Convert.
- Review XML — verify element nesting and array handling.
- Copy or download as
.xml.
FAQ
How are arrays converted?
JSON arrays become repeated XML elements with the same tag name. "hobbies": ["reading", "coding"] → <hobbies>reading</hobbies><hobbies>coding</hobbies>. This is the standard XML idiom for collections.
Is the XML declaration included?
Yes — output starts with <?xml version="1.0" encoding="UTF-8"?>. Required for strict XML parsers.
What if my JSON has keys with spaces or special characters?
XML element names can't contain spaces or start with numbers. Such keys produce invalid XML — rename them in JSON first (e.g., "first name" → "first_name") before converting.
Can I produce XML attributes instead of elements?
Not directly — JSON has no attribute concept. For SOAP/specific schemas needing attributes, use a library like xml-js with custom mapping rules.
Why use XML in 2026?
Mostly legacy / domain-specific: SOAP services in finance/government, RSS/Atom feeds, document formats (DOCX/EPUB use XML internally), Android/Java configs (AndroidManifest.xml, pom.xml), HL7 medical messaging. New systems almost always use JSON.
