Convert XML to JSON Converter

Online XML to JSON Converter

This free online XML to JSON converter transforms XML markup into structured JSON format directly in your browser. Whether you are working with REST APIs, data pipelines, or configuration files, converting XML to JSON enables easier data manipulation using modern JavaScript and web technologies.

What This Tool Does

The tool parses your XML input using a robust browser-safe XML parser and converts the document structure, including elements, text content, attributes, and nested nodes, into a JSON object. You can control whether attributes are included, whether numeric strings are parsed as numbers, and the output indentation level.

XML vs JSON: Why Convert?

JSON is lighter: JSON has less verbosity compared to XML, resulting in smaller payloads for APIs and network requests.
Native JavaScript support: JSON is natively supported in JavaScript via JSON.parse() and JSON.stringify(), making it easier to work with in web apps.
Simpler schemas: Many modern databases like MongoDB and PostgreSQL (JSONB) natively support JSON documents but not XML.
Tooling: Modern tools like jq, JSONPath, and most REST API clients work with JSON out of the box.

Frequently Asked Questions

How are XML attributes handled?

When "Parse XML attributes" is enabled, attributes are included in the JSON output with an "@_" prefix (e.g., @_category, @_lang). You can disable this to ignore attributes entirely.

Does this tool handle namespaces?

Basic namespace-prefixed elements are preserved in the JSON output as keys (e.g., "ns:element"). Full namespace resolution is not supported in this browser-based converter.

Is my XML data sent to a server?

No. All XML parsing and JSON conversion happen entirely inside your web browser. No data is uploaded to any external server.

What happens with repeated XML elements?

When the same element name appears multiple times under the same parent, the converter automatically groups them into a JSON array. For example, multiple <book> elements become a JSON array under the "book" key.
