JSON to XML Converter
Convert JSON to XML in your browser, no file uploads.
What it's for
Bridge between REST and SOAP
Guaranteed interoperability
Generates valid XML compatible with SAX and DOM parsers, SOAP services, and any legacy system.
100% private
Conversion happens in your browser. Your JSON is never sent to any server.
Well-formed XML
Output always meets well-formed XML rules: one root element, escaped characters, UTF-8.
Instant
XML updates in real time as you type. No buttons, no waiting.
How it works
Three steps, no hassle
Paste or type your JSON
Enter your JSON object or array in the left editor. The validator alerts you to syntax errors before converting.
Automatic conversion
XML is generated instantly as you type. Each JSON key becomes an XML element and arrays produce repeated child nodes.
Copy or download the XML
Use the copy button to grab the result to your clipboard, or download it as a ready-to-use .xml file.
FAQ

XML remains the required choice in enterprise environments using SOAP, WSDL, EDI, or standards like HL7 in healthcare and XBRL in finance. It is also preferable when the document needs rich metadata through attributes or requires validation with complex XSD schemas. JSON dominates modern REST APIs due to its lower verbosity, but XML holds clear advantages in legacy interoperability and native namespace support.
JSON has no explicit root element, while XML requires exactly one. The converter wraps the result in a <root> element by default. If your JSON object has a single top-level key, that key can serve as the root element. For JSON arrays, each item becomes a child node of the root element, e.g., <item>.
JSON has no concept of attributes — only key-value pairs. When generating XML from JSON, all keys are converted to child elements rather than attributes. If you need specific XML attributes, you must post-process the resulting XML manually or use a naming convention like '@attr' that some converters recognize.
JSON arrays have no direct equivalent in XML. The most common convention is to repeat the same child element for each array item. For example, ["a", "b"] inside a key 'item' generates <item>a</item><item>b</item>. This representation is valid XML but requires the consumer to know to expect repeated elements to correctly interpret the list.
Yes. The converter automatically escapes characters that have special meaning in XML: & becomes &, < becomes <, > becomes >, " becomes ". The resulting XML includes the <?xml version='1.0' encoding='UTF-8'?> declaration to indicate UTF-8 encoding, compatible with all Unicode characters including accented letters, CJK ideographs, and emoji.
JSON to XML: bridging the REST world with SOAP services and legacy systems
JSON and XML are the two most widely used data interchange formats in software development, but they emerged in different contexts with different philosophies. JSON (JavaScript Object Notation) arose in the 2000s as a lightweight alternative to XML for web APIs, leveraging JavaScript object syntax. XML (eXtensible Markup Language), standardized by the W3C in 1998, was designed for documents with complex structure, rich metadata, and formal validation via DTD or XSD.
The need to convert between the two formats arises constantly in enterprise environments. A team may build a modern REST API returning JSON but need to integrate it with a legacy ERP system that only accepts SOAP/XML. In sectors like healthcare (HL7 FHIR uses JSON but HL7 v2/v3 uses XML), finance (XBRL is XML), and government (many European interoperability standards are XML-based), bidirectional conversion is a daily task.
Convertir.ai processes the conversion entirely in your browser — your JSON never leaves your device. This is especially relevant when working with sensitive API data, configuration credentials, or customer information. The result is always well-formed XML with a UTF-8 encoding declaration, ready to be consumed by any standard XML parser.
