How do I convert XML to JSON?

Paste or upload XML, use Smart mode for the default mapping, then review and copy or download the JSON. Processing happens locally in your browser.

How are XML attributes represented in JSON?

Smart mode groups attributes in an @attributes object so they remain distinct from child elements. Controlled mode also lets you prefix attribute keys or omit attributes explicitly.

How are repeated XML elements converted to arrays?

Auto arrays convert repeated sibling elements into JSON arrays. Force Array lets you name elements that should stay arrays even when a particular document contains only one instance.

What happens to XML namespaces when converting to JSON?

Qualified names and namespace declarations are preserved by default. You can strip prefixes in Controlled mode, but conversion is blocked if two qualified names would collapse onto the same JSON key.

Why did a value like 00123 stay a string?

Strings are preserved by default because leading zeros, large integers, phone numbers, and dates are often identifiers. Optional Safe Infer converts only conservative booleans and precision-safe numeric forms.

Can this converter handle SOAP XML?

Yes. It detects SOAP 1.1 and SOAP 1.2 envelopes by namespace and can convert either the complete envelope or the Body content. It does not call a SOAP API or fetch remote resources.

Is my XML uploaded to a server?

No. Parsing and conversion run locally in your browser. The tool does not fetch remote XML, DTDs, schemas, or external entities, and it does not include raw input or output in analytics.

XML to JSON Converter

Use XML to JSON Converter locally with mapping controls, namespace and array handling, XML/JSON trees, diagnostics, and safe developer workflows.

Overview

What this tool does

XML to JSON Converter transforms XML into application-friendly or structure-preserving JSON locally, while showing how attributes, arrays, namespaces, text nodes, and mixed content were mapped so structural changes are not hidden.

Practical cases

Examples

API XML response

Convert an XML API payload into predictable application JSON without sending it to a server.

Repeated product list

See repeated sibling elements become arrays and force stable arrays for selected element names.

Attributes and text

Keep element attributes under @attributes while preserving the element text under #text when both are present.

Namespaced document

Preserve qualified names by default or strip prefixes only after collision checks pass.

SOAP response

Detect SOAP 1.1 or 1.2 envelopes and optionally convert the Body content only.

Mixed content

Preserve text and child order in #content so prose-like XML is not silently flattened.

Troubleshooting

Common errors

Malformed XML, mismatched tags, or multiple root elements prevent parsing.
Stripping namespace prefixes can create a collision between elements that have the same local name.
A single element maps to an object while repeated siblings map to an array; use Force Array when downstream shape must remain stable.
Leading-zero identifiers such as 00123 are corrupted by aggressive scalar inference; this converter preserves strings by default.
Mixed text and child elements require ordered #content rather than a simple object mapping.
DTD declarations and external entities are blocked because local conversion must never resolve external resources.
JSON cannot preserve every XML semantic automatically; review the Conversion Integrity report before relying on a compact mapping.

Use Agent Mapping Context to preview a local Markdown summary of the active profile, namespace and array rules, mapping decisions, diagnostics, and integrity results. Raw XML and JSON are excluded unless you explicitly enable a bounded excerpt and review the preview before copying.
