XML to JSON Converter (API, Data, Parse)

Bridge the gap between SOAP/Enterprise systems and modern REST APIs. Convert XML to JSON with attribute support.

Convert between XML and JSON formats instantly. Perfect for API integration.

A bi-directional structural bridge for migrating legacy enterprise data. Transform rigid XML payloads from outdated SOAP APIs into lightweight, modern JSON instantaneously. Powered by a robust DOM parser, this tool fiercely protects nested attributes and complex array typologies without requiring a roundtrip to a backend converter.

  • Unless a page explicitly says otherwise, files and text stay in the browser during processing.

The Legacy Systems Bridge

While GraphQL and REST APIs utilizing JSON completely dominate the modern software landscape in 2026, thousands of critical enterprise systems, banking mainframes, and government RSS feeds still stubbornly transmit data exclusively via XML (Extensible Markup Language). Our XML to JSON Converter is a vital translation layer, instantly converting these verbose payloads into lightweight, browser-native JSON objects.

Structural Preservation vs. Regex Hacks

Many cheap online converters use flaky Regular Expressions to strip <tags>, which catastrophically destroys nested data arrays and inline attributes. We engineered a fundamentally different approach. By leveraging a strict DOM-based parsing engine, the tool deeply understands the structural hierarchy of your data.

  • Attribute Persistence: When the engine encounters an XML attribute (e.g., <user id="404">), it intelligently translates it into a prefixed JSON property (e.g., {"@_id": "404"}), guaranteeing absolutely zero data loss during translation.
  • Automatic Array Folding: If a feed contains multiple <item> siblings, the engine automatically folds them into a perfectly formatted JSON array structure ([...]).

Rapid Reverse Translation

Need to communicate with a 15-year-old SOAP server that only accepts XML? Paste your modern JSON payload into the editor. The engine works flawlessly in reverse, generating a pristine, strictly formatted XML tree ready for transmission.

Key features

  • Bidirectional Engine: Convert an XML feed into a JSON object for your frontend, or turn a JSON config into XML for an older enterprise service.
  • Attribute Handling: Smartly manages XML attributes by prefixing them (default `@_`) or folding them into the object, ensuring no data is lost during conversion.
  • Code Folding & Minification: The output can be beautified for reading or compacted into a single line for efficient storage and transfer.

Frequently asked questions

How are XML attributes represented in JSON?

Attributes are usually converted to keys starting with `@_` or another prefix to distinguish them from child nodes (e.g., `<div class="box">` becomes `{"div": {"@_class": "box"}}`).

Can it handle CDATA sections?

Yes, the parser extracts text content from CDATA sections effectively, treating it as a standard string value in the resulting JSON.

is the conversion lossless?

Mostly yes, but because XML relies on order and JSON relies on keys (which are unordered), minor structural nuances regarding element order might change. Data values are preserved.
