How does the converter handle XML tag attributes?

Attributes are preserved as properties prefixed with *@_(e.g. becomes "@_id": "1").

How are repeated XML tags handled?

Multiple sibling elements with the same tag name are automatically grouped into a single JSON array.

Does this tool parse CDATA blocks?

Yes, CDATA sections ( ) are automatically unwrapped into their raw string content.

Quick Answer & Understanding Your Result

Source: W3C XML DOM Specification

An XML to JSON Converter transforms hierarchical W3C XML documents, RSS feeds, and SOAP payloads into structured JSON objects.

Core Parsing Features

Tag Hierarchy Mapping: Converts nested XML tags into matching nested JSON object trees.
Attribute Preservation: Maps XML element attributes into JSON properties using configurable attribute prefixes (@_attribute).
Array Grouping & Text Nodes: Automatically aggregates repeated identical child tags into clean JSON arrays, preserving text content and CDATA blocks.

API Migration & Integration Uses

Modernizing Legacy SOAP APIs: Transforming legacy XML web service outputs into modern REST JSON formats.
Feed & Sitemap Ingestion: Parsing RSS feeds, SVG markup, and XML sitemaps for consumption in JavaScript/TypeScript apps.

Paste your XML text above to convert it into clean, formatted JSON instantly.

Formula & Calculation Logic

Technical Specification & AST

Mathematical Formula

JSON Output

= XMLParser.parse(input, ignoreAttributes: false )

XML AST parsing:

Traverses XML DOM nodes.
Collates repeated elements into arrays and maps attribute values into prefixed properties.

Step-by-Step Guide

Paste XML Document

Paste well-formed XML code into the editor.

Deterministic DOM Parsing

The parser converts XML nodes into a JSON AST in 0ms.

Copy or Download .json

Copy the formatted JSON object or save as a .json file.
