XML to JSON Converter – Transform XML Data Online
Convert XML markup to JSON format online for free. Our best XML to JSON converter transforms XML data, attributes, and nested elements into structured JSON objects with custom indentation. Supports file upload, instant download, and live preview.
Quick Definition & Key Takeaways
XML to JSON conversion converts hierarchical Extensible Markup Language (XML) elements, attributes, and text nodes into structured JavaScript Object Notation (JSON) key-value objects and arrays.
- Maps XML Attributes to
@attributes - Converts Repeating Elements into Arrays
- Pretty Print or Minify JSON Output
How to Convert XML to JSON Online in 3 Simple Steps
Follow these simple steps to transform XML markup files or snippets into formatted JSON objects:
Enter XML Code
Paste XML code directly into the editor or upload an .xml or .txt file from your device.
Choose Indentation
Select space or tab indentation. Set indent count to 0 to produce a minified JSON payload for web APIs.
Copy or Download
Review the live JSON output, copy it to your clipboard with 1-click, or download a .json file instantly.
Feature Comparison: XML vs. JSON Data Formats
Compare key characteristics of XML and JSON formats for modern web applications and APIs:
| Feature | XML (Extensible Markup Language) | JSON (JavaScript Object Notation) |
|---|---|---|
| Syntax & Grammar | Verbose markup with explicit opening and closing tags (e.g. <tag>value</tag>) | Lightweight key-value pairs and native array structures (e.g. {"tag": "value"}) |
| JavaScript Parsing | Requires DOM parsing APIs like DOMParser() | Native 1-step parsing using JSON.parse() compliant with ECMA-404 Standard |
| Attribute Support | Native XML tag attributes (e.g. <item id="101">) | Converted into @attributes sub-objects during conversion |
| Primary Standard | Governed by W3C XML Core Specification | Specified in RFC 8259 JSON Format Specification |
How XML Attributes & Text Nodes Convert
When converting XML to JSON, tag attributes are nested under the @attributes key to preserve metadata. When an XML element contains both attributes and inner text content, the text node is assigned to the @value key.
Repeated XML tags under a single parent node are automatically converted into JSON arrays, preserving array order for list processing.
Who Needs XML to JSON Conversion?
- Full-Stack Developers: Migrate legacy SOAP or XML Web Services into modern RESTful or GraphQL APIs.
- Frontend Engineers: Convert XML config files or feed payloads into JSON objects for React, Vue, or Angular state.
- Data Engineers: Standardize incoming XML data files into JSON document formats for MongoDB or Elasticsearch.
- Mobile App Developers: Compact XML data streams into lightweight JSON payloads to optimize mobile bandwidth.

@attributes object property in the output JSON. For example, <item id="101"> becomes {"item": {"@attributes": {"id": "101"}}}. This preserves all attribute data without conflicts.0. This strips all whitespace and newlines, producing compact single-line JSON optimized for API transmission and reduced payload size.Best XML to JSON Converter Online

XML to JSON Converter for SAP CPI
SAP Cloud Platform Integration (SAP CPI) developers frequently need to transform XML payloads into JSON for connecting legacy SAP systems with modern REST APIs. Our XML to JSON converter in SAP CPI context allows you to test and validate transformation logic before deploying it in your integration flows.
Paste your IDoc XML, BAPI response, or any SAP-generated XML payload to see exactly how it maps to JSON. This helps debug content modifiers and Groovy script transformations in iFlow development.
XML to JSON Converter for Income Tax Files
Indian Income Tax XML files (ITR-1 through ITR-7, Form 16, 26AS, AIS) use structured XML format. Converting these to JSON makes it easier to extract specific fields, integrate with accounting software, or build custom tax calculation tools. Our XML to JSON converter Income Tax feature handles all standard ITR XML schemas accurately.
XML to JSON Viewer
Our XML to JSON viewer provides a live, formatted preview of the converted JSON output. You can instantly see how your XML structure maps to JSON objects, arrays, and nested properties. The viewer supports syntax-highlighted code display, character/line counts, and one-click copy — making it ideal for debugging and validation.
