XML and JSON are the backbone of data exchange on the web. While XML is highly descriptive and structured, JSON has become the standard for modern web APIs due to its lightness and ease of use in JavaScript. Our converter allows you to switch between these two essential formats instantly.
What is XML and JSON?
XML (eXtensible Markup Language) uses a tag-based structure similar to HTML, making it great for complex, hierarchical data. JSON (JavaScript Object Notation) is a text-based format that uses key-value pairs. Both are used to store and transport data, but JSON is typically easier for modern web applications to parse.

How to Convert XML to JSON
Paste XML Content
Paste your XML code into the input area. The tool will automatically validate the syntax.
Auto-Detect
The tool detects if your input is XML or JSON and sets the conversion direction.
Review Result
The converted JSON appears instantly. Nested tags are converted to nested objects/arrays.

Copy the result or download it as a .json file.
Key Features
Attribute Handling
Converts XML attributes into JSON properties with a prefix (e.g., _id).
Namespace Support
Correctly handles XML namespaces during transformation.
Prettified Output
Outputs cleanly formatted and indented JSON for readability.
Error Highlighting
Identifies malformed XML tags and provides location of errors.
Bidirectional
Easily convert back from JSON to XML.
Best Practices
- Ensure XML is well-formed with a single root element
- Validate XML namespaces if using SOAP or complex schemas
- Check for special characters that might need XML escaping
- Use meaningful tag names to generate clear JSON keys
- Verify how empty tags are represented (null vs empty string)
Common Use Cases
API Integration
Convert legacy XML API responses to JSON for modern frontend frameworks.
Web Development
Transform XML config files into JSON for simpler use in JavaScript apps.
Sitemap Mapping
Convert XML sitemaps to JSON for data analysis or custom processing.
Data Migration
Move data between systems that use different serialization formats.
Frequently Asked Questions
What happens to XML attributes?
Attributes are converted into JSON properties, usually prefixed with an @ or _ to distinguish them from child elements.
Does it support XML namespaces?
Yes, namespaces are preserved and converted into JSON keys.
Can I convert very large XML files?
Yes, as long as your browser has enough memory. Files up to 20-30MB are typically handled well.
Is it really private?
Yes. All conversion logic runs locally in your browser. No data is ever uploaded to our servers.
