About XML
What XML is
XML (eXtensible Markup Language) is a tag-based data format used heavily in enterprise systems, SOAP APIs, RSS feeds, SVG graphics, and document formats like DOCX and XLSX.
Enterprise and legacy systems
Many banking, healthcare, and government systems still communicate via XML or SOAP. Converting modern JSON API responses to XML is a common integration requirement.
Document and configuration formats
Android layouts, Maven POM files, Office Open XML documents, and RSS feeds all use XML. If you work across these ecosystems, XML conversion is a recurring need.
Why this tool helps
Writing XML by hand from JSON is tedious — tag names must be valid identifiers, special characters must be escaped, and nesting must mirror the object structure. This tool handles all of it.
Benefits
Why convert JSON to XML
XML powers many legacy systems and document formats that still form the backbone of enterprise integrations.
SOAP API integration
Many banking, insurance, and government APIs require SOAP requests with XML payloads. Converting from JSON is the fastest way to build those payloads from modern data.
Office document generation
DOCX, XLSX, and ODP files are ZIP archives of XML documents. Understanding the XML structure is the first step toward programmatic document generation.
Portable and validated
XML supports schemas (XSD) for validation and XSLT for transformation. Converting to XML opens the door to these tools without writing XML from scratch.
Built for valid XML output
Generates well-formed XML with an XML declaration, proper escaping, and correct nesting for any JSON structure.
XML declaration included
Every output starts with <?xml version="1.0" encoding="UTF-8"?> so the output is immediately usable as a standalone XML document.
Special character escaping
Ampersands, angle brackets, quotes, and apostrophes in string values are escaped to their XML entity equivalents automatically.
Arrays expand to sibling elements
JSON arrays produce repeated sibling elements under the parent tag — the most common convention for JSON-to-XML conversion.
Tag name sanitization
JSON keys that are not valid XML tag names (starting with digits, containing spaces) are sanitized to valid identifiers automatically.
In-browser, no upload
Conversion runs entirely in your browser. JSON that contains credentials, PII, or internal data never touches a server.
Questions about JSON to XML
Common questions about the conversion and the XML structure produced.
The root element is always <root>. JSON arrays produce <item> elements inside <root>. JSON objects produce one child element per key inside <root>.
Array items are repeated as sibling elements using the array's key name as the tag. For example, a users array produces multiple <users> elements.
Yes. JSON keys that start with digits or contain spaces and special characters are sanitized to valid XML identifiers automatically.
No. The conversion runs entirely in your browser. Your JSON payloads never leave your machine.
