Converts XML documents to JSON with configurable attribute handling (prefix, flatten, or promote), array detection for repeated elements, namespace stripping, and CDATA content extraction. Supports element-to-object or element-to-array mapping and preserves XML hierarchy in the JSON structure.
Modern APIs, frontend frameworks, and databases favor JSON over XML, but many legacy systems, SOAP services, and configuration files still use XML. This tool bridges the gap for data migration and integration without manual XML traversal.
This tool is part of the DevStackIO platform — a collection of free online developer tools from DevStackIO. Browse more free developer resources on DevStackIO.
Frontend developers consuming SOAP XML APIs, data migration engineers moving from XML to JSON databases, DevOps converting XML configs to JSON, and anyone integrating XML-based services with JSON-native tools.
Paste your XML content into the input editor; the tool parses the XML structure and validates well-formedness
Configure attribute handling: choose "@ prefix" (XML attributes become @attr keys), "flatten" (merge with elements), or "promote" (attrs at top level)
Enable array detection — repeated sibling elements with the same name become JSON arrays instead of overwriting
Toggle options: strip XML namespaces, extract CDATA as plain text, preserve comments, or handle empty elements as null
Click "Convert" and review the JSON preview; copy or download the result
Input: '<root><item id="1"><name>Alice</name></item><item id="2"><name>Bob</name></item></root>' with array detection -> Output: {"root":{"item":[{"@id":"1","name":"Alice"},{"@id":"2","name":"Bob"}]}}Input: '<data><![CDATA[Hello <world>]]></data>' with CDATA extraction -> Output: {"data":"Hello <world>"}What XML features are supported?
Well-formed XML, attributes, CDATA, processing instructions, namespaces, comments, and mixed content.
How are XML namespaces handled?
They can be stripped (flattened) or preserved as prefix:localname keys.
What happens to XML attributes?
They can be prefixed with @, flattened with elements, or promoted to top-level keys.
Does it handle XSD or DTD schemas? No, this is a structural converter
validation against schemas is not supported.
