XML to JSON Converter: Convert XML to JSON Online | Free Tool

A Attributes are stored in an @attributes object. For example, <item id="1"> becomes {"@attributes":{"id":"1"}}.

A Yes, the converter handles large XML files efficiently in your browser. For very large files (50MB+), consider a desktop tool.

A Yes, 100% free with no limits. No account needed.

A No, your data is never stored or uploaded to any server. This XML to JSON converter operates entirely within your browser, processing all conversions locally on your device. This ensures maximum privacy and security for your XML input, as no information leaves your computer. Feel confident converting sensitive XML files without concern for data retention.

A This converter processes CDATA sections by treating their content as regular string values within the resulting JSON output. For instance, `<example><![CDATA[<p>Hello World</p>]]></example>` will be accurately converted to `{"example": "<p>Hello World</p>"}`. It ensures that any embedded markup, special characters, or structured text within CDATA blocks are preserved exactly as plain strings in the JSON, making it reliable for data integrity in web development and API contexts.

A This converter processes XML namespaces by including them as part of the element names in the resulting JSON, typically using the `prefix:localname` format. For example, an XML element like `<soap:Envelope>` would be converted to a JSON key such as `"soap:Envelope"`. This ensures the original namespace information is preserved within the JSON structure, making it straightforward to reconstruct or parse according to the original XML schema. It maintains data integrity for complex XML documents in web development and API contexts.

A Duplicate elements like <item>Apple</item><item>Banana</item> get converted into a JSON array: ["Apple","Banana"]. If there's only one element, it stays as a single string. This matches how most APIs expect data. QA testers should watch for this when validating network configs.

A XML always requires a single root element by definition. The converter wraps your content in one JSON object using that root tag as the key. For example, <catalog><book>...</book></catalog> becomes {"catalog":{...}}. This isn't a bug — it's how XML works. If you need the raw items without the wrapper, extract the inner array after conversion. QA testers flatten this structure for API payloads that expect arrays at the top level.

A Yes, self-closing tags convert to empty strings in JSON. So <br/> becomes {"br": ""} and <img src="photo.jpg"/> becomes {"img": {"@attributes": {"src": "photo.jpg"}}}. Null elements require special handling — they won't turn into JSON null values. Junior devs often expect null but get empty strings instead. Quick tip: if your downstream system needs explicit nulls, add a post-processing step to replace empty strings.

A No, comments get stripped out entirely. So <!-- user ID --> becomes invisible in the final JSON. This matches how most APIs handle data — comments aren't part of the payload. If you're QA testing config files, add a visual marker like <note> instead of relying on comments. That way you'll see it in the output.
