XML To JSON

XML attributes are converted to JSON properties with a prefix (default @ symbol) to distinguish them from element content. For example, <item id="1" type="product"> becomes {"@id":"1", "@type":"product", ...} in JSON. You can customize the prefix to reduce verbosity or match your schema preferences.

When merge text nodes is enabled, text content is placed in a #text property when elements also contain children. For example, <p>Hello <strong>world</strong></p> becomes {"#text":"Hello ", "strong":"world"}. Disable merging if you need fine-grained separation of text and element content.

Yes, when "Preserve order" option is enabled, element order is maintained in the JSON output. However, standard JSON objects don't guarantee property order in all contexts, so enable this option if order matters for your use case. When disabled, order may vary based on JSON object implementation.

Yes, use the "JSON to XML" reverse conversion feature or tool to verify round-trip fidelity. This helps ensure the conversion is reversible and that critical XML structure, attributes, and content are preserved during conversion, catching any data loss or transformation issues.

Usually yes, with attributes and text represented as JSON properties. However, some XML nuances like whitespace handling, comment preservation, processing instructions, or CDATA sections may be normalized or lost depending on conversion settings. Test round-trip conversion to verify fidelity for your specific XML structures.

Conversion is performed entirely in your browser using client-side JavaScript. No XML data is uploaded to servers, ensuring complete privacy, security, and compliance with data protection regulations—perfect for sensitive business data, confidential documents, or regulated information that cannot leave your device.

XML namespaces are preserved in element names or can be stripped/renamed based on conversion options. Consider the semantic meaning of namespaces before modifying them, as they often provide important schema or classification information that may be required for proper data interpretation in target systems.

Auto detects when elements repeat and creates arrays automatically; force arrays always creates arrays even for single elements (useful when consumers always expect arrays); never arrays always uses objects (useful when structure must be consistent regardless of element count). Choose based on your target schema requirements.

The tool attempts to parse and convert XML, but well-formed XML produces the best results. Malformed XML may cause parsing errors or produce unexpected JSON structures. Validate and fix XML structure issues before conversion for reliable, accurate JSON output that matches expected schemas.

Browser-based conversion works best for files under ~10MB due to memory limitations. For larger XML files or extremely deep nesting (50+ levels), consider splitting files, using server-side conversion tools, or preprocessing XML to reduce complexity before conversion to prevent browser performance issues or memory exhaustion.

XML comments and processing instructions are typically not preserved in JSON conversion, as JSON doesn't have direct equivalents. CDATA content is treated as regular text. If these XML features are critical, document them separately or use specialized conversion tools that preserve all XML features.

The auto-convert option uses standard detection (numeric strings become numbers, "true"/"false" become booleans). For more control, disable auto-convert and perform type transformations in your application code, or use JSON Schema validation to ensure types match your requirements after conversion.
