About this xml ↔ json converter
Convert supported XML to JSON or supported JSON to XML locally. CDATA is treated as text; XML spelling and original bytes are not guaranteed to be preserved Transforms and validates developer data structures locally, preventing confidential payload exposure during data wrangling.
Syntax parsing & data transformation logic
Converts supported XML and one-root JSON mappings in either direction. Attributes use `@`; ordered text, child elements, comments and processing instructions use `#content`. CDATA is treated as text, so this is not byte-for-byte or lexical round-trip preservation.
Worked conversion & output example
Scenario: Convert one XML child into the documented JSON shape.
Sample input:
Processing: Select XML to JSON and preserve child ordering in #content.
Illustrative output:
Syntax constraints & input size limits
Input is capped at 1,000,000 UTF-16 code units, output at 8,388,608, and nesting at 100 elements. DOCTYPE is rejected. JSON-to-XML requires exactly one root key and the supported `@`/`#content` shape; arbitrary JSON and XML constructs are not supported.
Data conversions and formatting in XML ↔ JSON Converter reflect standard structured syntax. Verify parsed outputs against your target runtime before deployment.
Local client execution boundary
Data parsing and transformations in XML ↔ JSON Converter execute in the local browser tab without remote data transmission.

How to use it
- Paste XML or a single-root JSON mapping and select the direction.
- For XML, parse elements into a root-keyed object with `@` attributes and ordered `#content`; for JSON, reconstruct one XML root from that mapping.
- Read the serialized JSON or XML result; invalid structures produce an error.
Frequently asked questions
How does XML to JSON represent a child element in this converter?+
With `<root><item>Ada</item></root>` and XML to JSON selected, the output places the child in `root.#content` as `{ "item": "Ada" }`.
How are XML attributes, text, comments, and processing instructions represented?+
The interchange representation uses `@` for attributes and `#content` for ordered content. It has constrained forms for comments and processing instructions rather than arbitrary JSON objects.
Can this tool convert any JSON object into XML?+
No. JSON-to-XML accepts only the documented XML-shaped structure and valid XML names and characters. Unsupported object shapes, malformed comments, and unsafe document structures are rejected.
Does XML ↔ JSON conversion preserve every lexical XML detail?+
It converts the supported structure, not a byte-for-byte XML archive. Check namespaces, entities, whitespace, declaration details, and schema rules separately when exact interchange matters.
