XML to JSON Converter

About XML to JSON Converter

The XML to JSON Converter parses any well-formed XML document and transforms it into a clean, structured JSON representation. This is essential when migrating data from XML-based systems to modern JSON APIs, processing legacy SOAP responses in JavaScript applications, or converting configuration files between formats. The tool handles elements, attributes, namespaces, CDATA sections, and deeply nested structures with full fidelity.

Why Convert XML to JSON?

JSON has become the dominant data interchange format for web applications, REST APIs, and NoSQL databases. However, many enterprise systems, financial protocols, government data feeds, and legacy applications still produce XML. Converting XML to JSON enables modern front-end frameworks (React, Vue, Angular) and Node.js backends to consume data that was originally designed for SOAP and XML-based workflows. It also simplifies data storage in document databases like MongoDB, CouchDB, and Elasticsearch.

Key Features

• Full XML support — handles elements, attributes, namespaces, CDATA sections, processing instructions, and mixed content.
• Smart type detection — automatically converts numeric strings to numbers and boolean text values to true/false in JSON.
• Pretty-print output — generates well-indented, readable JSON with 2-space or 4-space formatting options.
• Array detection — identifies repeated XML sibling elements and converts them to JSON arrays automatically.
• Attribute prefix — XML attributes are prefixed with @ in the JSON output to distinguish them from child elements.
• Text content handling — mixed content elements preserve both text and child element data in the JSON structure.

How to Use

1. Input XML — paste your XML into the input editor, upload an .xml file, or fetch XML from a URL.
2. Convert — click Convert or press Ctrl+Enter to parse and transform the XML.
3. Inspect output — view the JSON result in the right panel with full syntax highlighting.
4. Export — copy the JSON to your clipboard or download it as a .json file.

Conversion Rules

Understanding how XML structures map to JSON helps you predict the output and work with it effectively:

• Each XML element becomes a JSON key with its children as the value (object or string).
• XML attributes are represented as keys prefixed with @ (e.g. "@id": "123").
• Repeated sibling elements with the same tag name become a JSON array.
• Elements with only text content become simple string (or number/boolean) values.
• CDATA content is extracted as plain text and placed in the corresponding JSON string.
• Empty elements become empty strings or null in the JSON output.

Real-World Use Cases

• Converting SOAP/XML API responses to JSON for consumption by JavaScript front-end applications.
• Migrating legacy XML configuration files (web.config, app.config) to modern JSON-based config systems.
• Parsing XML exports from Oracle, SQL Server, or SAP and transforming them into JSON for MongoDB import.
• Creating JSON test data from existing XML fixtures in automated testing pipelines.
• Transforming RSS/Atom XML feeds into JSON for modern content aggregation dashboards.
