JSON to XML Converter
Convert JSON objects and arrays to XML with configurable roots, attributes, and text nodes
Arrays repeat the same element name. Keys beginning with the attribute prefix become parent attributes.
Generated XML will appear here.
About this tool
JSON to XML Converter builds a browser DOM from any valid JSON value and serializes it as readable XML. Object keys become child elements, arrays repeat the same element name, root arrays use a configurable item name, and primitive values become text. A configurable prefix such as @ maps object properties to parent-element attributes, while a key such as #text adds direct text beside child elements. Root name, item name, attribute prefix, text key, and XML declaration are adjustable. XML-special characters in values are escaped by DOM APIs, and unsupported name characters are normalized. JSON has no standard one-to-one XML mapping, so namespace declarations, mixed-content ordering, type annotations, empty-array intent, and schema-specific element choices require manual review.
Scenario Recipes
Draft an XML payload from a JSON API fixture
Goal: Make an initial mapping explicit before implementing a production serializer
- Paste a sanitized representative JSON object and choose the root element required by the receiving API.
- Mark intended attributes and direct text with the configured prefix and text key, then generate XML.
- Review arrays, empty values, normalized names, and element order before validating against the official schema.
Result: A readable mapping draft that can guide, but does not replace, a schema-aware serializer.
Frequently Asked Questions
How are JSON arrays represented in XML?
Arrays repeat the same element name. A root-level array repeats the configured item element inside the root.
How can JSON values become XML attributes?
Put the configured prefix before a key, such as @id. That key is written as an attribute on the surrounding element.
What is the #text key for?
It adds direct text to an element that may also contain attributes or child elements.
Are special characters escaped safely?
Yes. XML nodes and attributes are created with DOM APIs, so value escaping is handled during serialization.
Can the output be validated against XSD?
No. The tool creates generic XML and does not load schemas, namespaces, or partner-specific mapping rules.
Is the JSON uploaded?
No. Parsing, DOM construction, formatting, copying, and downloads run locally.
