XML to JSON Converter

How to Use the XML to JSON Converter

This free online XML to JSON converter transforms XML markup into clean, structured JSON output instantly in your browser. Whether you're migrating legacy SOAP API responses, converting configuration files, or building data transformation pipelines, this tool preserves nested elements, attributes, and arrays while generating valid JSON that's ready to use in modern JavaScript applications.

Step-by-Step

1. **Paste your XML** into the input panel.

Click Convert — The tool parses the XML and generates formatted JSON output instantly.

Copy the JSON — Use the Copy button to grab the result for your code, API, or data pipeline.

The converter handles namespace prefixes, CDATA sections, and deeply nested structures automatically.

Features

Accurate structure preservation — Nested XML elements map to nested JSON objects. Repeated elements become JSON arrays.

Attribute handling — XML attributes are preserved with a configurable prefix (default: @).

CDATA support — CDATA sections are extracted as plain text values.

Pretty-printed output — JSON output is indented and formatted for readability.

Error reporting — Invalid XML is flagged with clear parsing error messages.

One-click copy — Copy the JSON output to your clipboard instantly.

Zero server calls — All parsing happens in your browser using the DOMParser API.

Common Use Cases

SOAP to REST Migration — Convert XML responses from legacy SOAP APIs into JSON format for consumption by modern REST or GraphQL clients.

Configuration File Conversion — Transform XML config files (Maven pom.xml, Spring XML configs, Android manifests) into JSON for tools that prefer JSON input.

Data Pipeline Integration — Convert XML data exports from enterprise systems (SAP, Salesforce, government feeds) into JSON for ingestion by Node.js, Python, or data warehousing tools.

RSS/Atom Feed Parsing — Convert RSS or Atom XML feeds into JSON for display in web applications or processing in JavaScript.

Testing and Mocking — Generate JSON test fixtures from XML sample data for API testing frameworks like Jest, Supertest, or Postman.

Tips for Power Users

- When your XML has repeated child elements with the same tag name, the converter automatically creates a JSON array — no manual adjustment needed.

- For XML with mixed content (text nodes alongside child elements), text content is preserved as a #text property.

- Combine this tool with the JSON Formatter to further prettify or minify the output.

- Use the JSON Path Explorer afterward to navigate and query the converted JSON structure.

- For very large XML documents, consider splitting them into sections and converting each part separately.

Why Use This Tool?

This XML to JSON converter runs entirely in your browser using the native DOMParser API — no server uploads, no third-party libraries, and no data collection. Your XML content stays on your device throughout the conversion process. It's fast, handles edge cases like namespaces and CDATA, and produces clean JSON that's ready for immediate use in your applications.
