How do I convert XML to JSON?

Paste your XML data into the converter, configure options like attribute handling and array detection, then click Convert. The tool transforms XML into JSON instantly with automatic type conversion and structure preservation.

Is this XML to JSON converter free?

Yes, completely free with no limits on conversions. No signup required, no watermarks. All processing happens in your browser for complete privacy.

Are my XML files uploaded to servers?

No, all XML to JSON conversion happens locally in your browser. Your data never leaves your computer, ensuring complete privacy for sensitive XML documents and configuration files.

How are XML attributes converted to JSON?

XML attributes are converted to JSON properties with a prefix (default "@"). For example, <element attr="value"> becomes {"@attr": "value"}. This preserves all attribute data in the JSON output.

How does the tool handle repeated XML elements?

Repeated elements are automatically converted to JSON arrays. You can configure whether to force arrays, use smart detection, or avoid arrays entirely based on your needs.

Can numbers and booleans be parsed automatically?

Yes, the tool can automatically parse string values that look like numbers or booleans (true/false) into their proper JSON types for cleaner data structures.

How are XML namespaces handled?

Namespaces can be preserved in element names using a configurable separator, or they can be ignored during conversion depending on your requirements.

What happens with mixed content (text + elements)?

Mixed content is handled by separating text into a special text node property (default "#text") while preserving child elements for complete data preservation.

Can I convert SOAP responses to JSON?

Yes, our converter handles SOAP envelope structures and extracts the body content to JSON format. It properly processes SOAP namespaces and nested response data for use in modern JavaScript applications.

How do I handle XML with CDATA sections?

CDATA sections are converted to regular text content in JSON. The CDATA wrapper is removed, and the content is placed in the appropriate text node property, preserving any special characters without escaping.

What is the difference between @ and _ for attribute prefixes?

Both are common conventions. The @ prefix is more widely used and clearly indicates attributes. The _ prefix may be preferred if your JSON will be used in languages where @ has special meaning. Choose based on your application requirements.

Can I convert large XML files?

Yes, the converter efficiently handles XML files up to several megabytes. For very large files (>10MB), processing time may increase. The tool shows progress and conversion statistics to track processing of large documents.

How do I preserve XML element order in JSON?

JSON objects technically do not guarantee key order, though modern JavaScript engines preserve insertion order. Our converter maintains the original element order from the XML during conversion for practical purposes.

What if my XML has encoding declarations?

XML encoding declarations (like <?xml version="1.0" encoding="UTF-8"?>) are automatically handled. You can optionally ignore the declaration in output. The converter supports UTF-8 encoded content by default.

Can I use this for RSS or Atom feed conversion?

Absolutely! The converter handles RSS and Atom XML feed structures, converting channel information, items, and metadata to JSON format suitable for JavaScript feed readers and aggregators.

How do I convert JSON back to XML?

Use our companion JSON to XML Converter tool for reverse conversion. It handles the inverse transformation, converting JSON objects and arrays back to well-formed XML documents with proper element structure.

Does the converter validate XML before conversion?

Yes, basic XML validation checks for well-formedness including matched tags, proper nesting, and valid syntax. Validation errors are reported with line numbers and descriptions to help fix issues before conversion.

What happens to XML comments during conversion?

By default, XML comments are ignored during conversion since JSON has no comment syntax. You can optionally preserve comments as special properties if you need to retain this information in the output.
