JSON to XML Converter - Well-Formed Output in One Paste

Paste any JSON and get properly indented, well-formed XML output immediately. Every JSON object becomes an XML element, arrays produce repeated sibling tags, special characters are escaped as XML entities, and null values become self-closing tags. Choose your root element name and indentation style before exporting.

REST APIs return JSON but enterprise systems - banking, insurance, healthcare (HL7 FHIR), ERP platforms like SAP - still largely communicate in XML. SOAP web services require XML request bodies. Microsoft BizTalk, IBM MQ, and many EDI platforms expect XML. When you have JSON data that needs to enter an XML-based system, this converter handles the translation without requiring code.

Conversion Rules

JSON object → XML element with child elements for each key. JSON array → repeated sibling elements with the same tag name (customizable). JSON string → text content with special chars escaped (& < > "). JSON number/boolean → text content, unquoted. JSON null → self-closing tag (<fieldName/>). Keys with spaces or invalid XML characters are sanitized into valid element names automatically.

SOAP Integration

When calling SOAP services from a REST-native codebase, this converter helps build the XML Body content. Paste your JSON data model, convert it, then wrap the output in the SOAP Envelope and Body structure your service expects. The converter handles the data XML - you add the SOAP wrapper separately.

Frequently Asked Questions

Arrays produce repeated child elements. {'colors':['red','blue']} becomes (colors)(item)red(/item)(item)blue(/item)(/colors). The item element name is customizable - change it to match your XML schema requirements.

Null values become self-closing XML elements: (fieldName/) or with xsi:nil='true' if you enable XSI nil annotations for schema-validated XML.

Yes. Nesting depth is limited only by browser memory. JSON nested 10-20 levels deep converts to correctly indented nested XML elements.

It produces well-formed XML with proper UTF-8 encoding and escaped special characters. It is not automatically schema-valid (XSD-valid) - that depends on whether your JSON data matches the target XML schema's constraints.

XML element names cannot start with digits. Keys like '1stItem' are prefixed with an underscore: '_1stItem'. Keys with spaces become underscore-separated: 'first name' → 'first_name'. All sanitization is shown in the output.
