Is the XML to JSON conversion lossless?

Yes. XML attributes are preserved under "@attributes" keys, mixed text content under "#text", and repeated tags become arrays. The structure round-trips faithfully for most XML documents (excluding comments and processing instructions, which JSON cannot represent).

Does it handle XML namespaces?

Namespaced elements are preserved with their prefix in the JSON key (e.g., "ns:tag" stays as "ns:tag"). The xmlns attribute is captured under "@attributes" so you can re-emit the namespace if needed.

What's the maximum XML file size?

There's no hard limit, but conversion happens in your browser's memory. Files under 10MB convert instantly; very large files (50MB+) may take a few seconds and consume RAM proportional to the document size.

Is my XML data sent to a server?

No. All parsing happens locally in your browser using the native DOMParser API. Your data never leaves your device — there are no analytics, no logs, no uploads.

Can I convert the JSON back to XML?

Yes — use our companion JSON to XML converter. The "@attributes" and "#text" conventions are recognized in both directions for round-trip conversion.

Why are some elements showing as null?

Empty XML elements (like ) become null in JSON because they have no content and no attributes. If they had attributes, you'd see {"@attributes": {...}} instead.

About XML to JSON Conversion

XML and JSON are the two most common data interchange formats on the web. Legacy SOAP APIs, RSS feeds, configuration files, and enterprise systems still rely heavily on XML, while modern REST APIs and JavaScript applications expect JSON. Converting between them is a daily task for backend developers, data engineers, and integrators.

Why convert XML to JSON?

JSON is lighter, easier to parse in JavaScript, and natively supported by most modern languages. When integrating a legacy XML feed into a React app, mobile client, or NoSQL database, converting to JSON eliminates parsing overhead and simplifies your data pipeline.

How our converter handles XML attributes

XML supports attributes (e.g., <user id="1">) that JSON does not natively express. Our parser preserves them under a special "@attributes" key on the resulting object, so no information is lost in the conversion. Mixed content (text inside elements with children) is preserved under "#text".

Arrays vs single elements

When the same XML tag appears multiple times under a parent, we automatically convert it to a JSON array. A single occurrence becomes a plain object. This produces idiomatic JSON that's easy to consume from JavaScript without extra normalization.

What's preserved during conversion

Element names → JSON object keys
XML attributes → "@attributes" sub-object
Text content → string values (or "#text" key for mixed content)
Repeated tags → JSON arrays
Nested hierarchies → nested JSON objects
Unicode and UTF-8 character encoding
