JSON to XML Converter — Transform Data Formats Instantly
JSON and XML are the two most common data interchange formats. While JSON is lighter and more popular for APIs, XML is still widely used in SOAP web services, RSS feeds, and enterprise systems. This tool converts JSON to well-formatted XML with proper escaping of special characters.
Paste valid JSON and get properly indented, well-formed XML output. The converter handles nested objects, arrays, primitive types, and special characters that need XML escaping (ampersands, angle brackets, quotes). Arrays are represented as repeated elements with consistent tag names.
XML remains the required format for many enterprise integrations. Banking APIs, healthcare systems (HL7/FHIR), government submissions, and SOAP-based services all expect XML input. If your application produces JSON but a downstream system needs XML, this converter bridges the gap without writing custom transformation code.
One key difference between JSON and XML is that XML supports attributes on elements, while JSON has no direct equivalent. This converter maps all JSON data as child elements. If your target XML schema requires attributes, you may need to adjust the output manually or use an XSLT transformation.
For the reverse conversion, use our JSON Formatter which validates and beautifies JSON. Developers working with both formats regularly can use our JSON Formatter alongside this tool for a complete data format workflow.

- Click Convert to transform JSON into well-formed XML
- Copy or download the resulting XML document
When to Convert JSON to XML
XML is still required by many enterprise APIs, SOAP services, and legacy systems like banking and healthcare integrations. When converting, JSON arrays become repeated XML elements, and JSON keys become XML tags. Keep in mind that XML attributes have no direct JSON equivalent — this converter maps everything as child elements. Validate the output against your target XML schema if one exists.
When to Use the JSON to XML Converter
Use this converter when integrating with SOAP-based web services, generating RSS or Atom feeds from JSON data, submitting data to government or banking APIs that require XML, migrating data between systems with different format requirements, or building configuration files for XML-based frameworks.
Common Use Cases
- •Convert REST API responses to XML for legacy system integration

Expert Tips
- ✱Validate your JSON input first using our JSON Formatter — the converter will reject malformed JSON.
- ✱If your target system requires XML attributes rather than child elements, you will need to restructure the output manually or use an XSLT transform.
- ✱For large JSON files, be aware that XML is typically 30-50% larger than the equivalent JSON due to closing tags and verbose syntax.
- ✱Test the converted XML against your target XSD schema if one exists — structural validity does not guarantee schema compliance.
Frequently Asked Questions
- JSON arrays become repeated XML elements with the same tag name. For example, {"items": ["a", "b", "c"]} becomes three <items> elements. The specific tag name depends on the parent key in the JSON structure.
- This tool converts JSON to XML only. The reverse conversion (XML to JSON) requires different handling for attributes, namespaces, and mixed content that JSON does not natively support. Use a dedicated XML-to-JSON tool for that direction.
- Yes. Characters that are special in XML (< > & " ') are automatically escaped in the output. For example, a JSON value containing 'A & B' becomes 'A & B' in the XML output.
- The converter produces namespace-free XML by default. If your target schema requires namespaces, you will need to add the namespace declarations (xmlns attributes) to the output manually.
