XML ↔ JSON Converter

Convert between XML and JSON with attribute and nesting support.

Input (XML)
Output (JSON)

Paste XML to convert…

Conversion Details

XML → JSON

Converts XML elements to JSON objects, attributes to @ prefixed keys, and handles text nodes, nested elements, and arrays.

JSON → XML

Converts JSON objects to XML elements, @ prefixed keys to attributes, with proper escaping and XML declaration header.

All conversion happens locally in your browser. No data is sent to any server.

How Xml To Json Works in Your Browser

The ToolsForgess XML to JSON converter transforms XML documents into valid JSON output with correct handling of attributes, text content, nested elements, and repeated tags. Paste your XML string or upload an XML file, and receive the equivalent JSON structure instantly. The conversion engine parses XML using the browser's DOMParser and constructs a JSON object that preserves the document's hierarchical relationships — all without transmitting any data to a server. Attribute-to-property mapping, array detection for repeated elements, and text content extraction follow standard XML-to-JSON conversion conventions. This tool is essential for developers integrating legacy XML APIs with modern JavaScript applications, converting XML configuration files to JSON for Node.js environments, and preparing XML data for processing with JSON-based toolchains.

Key Features

  • Map XML attributes to JSON properties with configurable naming conventions. Attributes can be prefixed, nested, or merged with element text content based on your preference.
  • Detect repeated sibling elements and automatically wrap them in JSON arrays. The converter correctly handles mixed content elements with both text and child nodes.
  • Preserve the full hierarchical structure including deeply nested elements, namespaces, and processing instructions in the JSON output.
  • All XML parsing and JSON serialization occur entirely within the browser. No data is transmitted to any server during conversion.

Frequently Asked Questions

How are XML attributes represented in JSON?
By default, attributes are prefixed with an at-sign and nested under the element key. For example, an attribute id="123" becomes "@id": "123" in the JSON output. This convention can be customized.
Does it handle XML namespaces?
Namespace declarations are preserved in the JSON output. Namespace prefixes are included in element and attribute names to maintain semantic fidelity during conversion.
Can I convert JSON back to XML?
The current tool converts XML to JSON only. For the reverse operation, use the Format Transformer tool which supports bidirectional conversion between XML and JSON.
Is my XML data uploaded during conversion?
No. All XML parsing and JSON serialization occur entirely within the browser. Your XML content never leaves your device.

All data processing for Xml To Json runs 100% locally in your browser using client-side JavaScript. No data is uploaded to any server.

Technical Specification

XML-to-JSON Conversion Engine & Data Transformation

Overview

The ToolsForges XML-to-JSON converter transforms XML documents into clean, properly structured JSON objects, enabling developers to migrate data feeds, convert configuration formats, and bridge XML-based APIs with modern JSON-native applications. Paste your XML string and receive an instantaneous conversion that preserves element hierarchy, attribute mapping, and text content.

Feature Specifications

  • Attribute PreservationConvert XML attributes to JSON properties using configurable naming conventions, ensuring that metadata stored in attributes is preserved in the converted output without data loss.
  • Array Handling OptionsConfigure how repeated XML elements are converted — as JSON arrays or sequential properties — to match the conventions expected by your consuming application.
  • Text Content ExtractionExtract text content from mixed-content XML nodes and map them to JSON properties, preserving the semantic meaning of elements that combine text and child elements.
  • Pretty-Print OutputReceive the converted JSON with configurable indentation for immediate readability, or compact output for production use where file size is a priority.

Architecture

The converter uses React useState for XML input and the browser's DOMParser API for parsing. The conversion engine traverses the DOM tree, mapping element names, attributes, and text content to JSON properties following configurable conventions.

Frequently Asked Questions

How are XML namespaces handled in the JSON output?

Namespaced element names are preserved as-is in the JSON property names. You can configure whether namespace prefixes are included or stripped based on your conversion requirements.

Can I convert SVG files to JSON?

Yes. SVG is XML-based and the converter processes it like any other XML document. The resulting JSON represents the SVG element hierarchy as nested objects.

Does the converter handle CDATA sections?

Yes. CDATA sections are extracted as text content and mapped to the corresponding JSON property, preserving the original text without the CDATA wrapper.

Is my XML data stored?

No. All XML input and converted JSON output are processed entirely within your browser. No document data is transmitted to external servers.
