Validate data XML, preserve text values and attributes, then copy or download formatted JSON without uploading the source.
Your checked result will appear here.
Ordinary elements, attributes and text cross the validation boundary. Document types and custom entity declarations stop before the parser constructs an object.
The converter uses explicit mapping rules. It does not infer numeric types or discard attributes to make the output look simpler.
Closing tags, quoting and the single-root structure must be valid before conversion begins.
Child elements become nested object properties; repeated siblings become arrays.
Attribute names receive an @ prefix so they cannot silently collide with child element names.
Text and attributes remain strings, preserving leading zeroes and values such as 12.50.
This fixture is covered by the product test. Four elements and two attributes become one nested object; the price remains the string 12.50.
<catalog version="1">
<item id="sku-1">
<name>Notebook</name>
<price>12.50</price>
</item>
</catalog>{
"catalog": {
"item": {
"name": "Notebook",
"price": "12.50",
"@id": "sku-1"
},
"@version": "1"
}
}<!DOCTYPE catalog [...]>Document types and custom entity declarations are outside this data-conversion boundary.
Well-formed XML can still violate the contract expected by another system. Conversion preserves structure; it does not certify semantics.
Check whether a downstream consumer expects an array even when the source contains only one occurrence.
Elements that mix text and child tags may need a domain-specific representation rather than a generic object map.
Prefixes remain part of names. Confirm how the destination identifies namespace URIs and qualified fields.
Run an XSD or application validator separately when element order, allowed values or required fields matter.
Comments, processing instructions, schema definitions and document-level entity behavior are not the goal of this data utility.
