XML to JSON Converter Reference & Mapping Rules

The XML to JSON converter transforms nested XML tags and schema structures into standard JSON data objects. In modern application stacks, consuming raw XML in frontend JavaScript or serverless Node.js functions requires bulky parser dependencies. Converting XML payloads directly into JSON provides native compatibility with modern REST APIs, MongoDB, PostgreSQL JSONB fields, and TypeScript interfaces.

How XML Constructs Map to JSON

  • Repeating Elements to Arrays: Sibling elements sharing identical tag names (such as multiple <item> tags) automatically combine into a JSON array of objects.
  • Attribute Prefixing: Tag attributes can be preserved with a distinct prefix (e.g. @id or _id) or mapped directly as standard object properties.
  • Type Coercion: When enabled, numerical strings and booleans ("true", "false") automatically convert to native JSON numbers and boolean literals.
  • Mixed Content & CDATA: Tags containing both text content and child tags isolate their character data cleanly into #text properties without data corruption.

Privacy & Security

  • 🔒 All processing happens in your browser – no files are uploaded.
  • 🚫 No server interaction – everything runs locally using the native browser DOMParser.
  • 🕵️ No tracking, no logging – your data stays yours.
  • 💼 Safe for sensitive data – perfect for confidential enterprise or financial files.

Frequently Asked Questions

How are repeated XML tags handled?

When sibling tags share the same name (such as multiple <item> tags), they are automatically aggregated into a JSON array of objects.

Can I customize attribute names in the output?

Yes – use the Attribute Prefix dropdown to prefix attributes with @ (default), _, or no prefix.

Is the JSON output valid and formatted?

Yes – it is valid JSON formatted with 2-space indentation, ready to integrate into any application.

How are mixed content tags containing both text and child elements handled?

For elements with mixed content or attributes alongside text, DataFrog isolates the text node into a #text property while representing child tags and attributes as sibling properties, ensuring zero data loss.

Can I convert SOAP envelopes or XML RSS feeds with namespaces into JSON?

Yes! DataFrog handles XML namespaces gracefully by preserving tag local names or prefixes according to W3C DOM specifications, allowing RSS, Atom, and SOAP payloads to convert into clean JSON objects.
