XML to TypeScript Converter
Convert XML documents to TypeScript interfaces with automatic type inference. Generates strongly-typed interfaces from XML structures with support for attributes, nested elements, and arrays.
Conversion Options
Use interface vs type
Add export keyword
Keep original vs camelCase
Add ? to all properties
Add readonly modifier
Add ; at end of properties
Order alphabetically
Type[] vs Array<Type>
Parse XML attributes
Flatten into same interface
Detect number, boolean, Date
Recommended Settings
TypeScript Best Practices
- •Use interfaces for object shapes - they're more extensible and familiar to TypeScript developers
- •Enable export types to make interfaces reusable across your codebase
- •Use camelCase for property names (disable 'Preserve Element Names') for TypeScript conventions
- •Enable type inference to get number, boolean, and Date types instead of all strings
- •Merge attributes into main interface for cleaner types unless you need clear separation
Common Use Cases
- •API development: Generate types from XML SOAP/REST responses for type-safe clients
- •Data validation: Use generated types with Zod or io-ts for runtime type checking
- •Migration: Modernize XML-based systems with strongly-typed TypeScript interfaces
- •Configuration: Type-safe XML config file parsing with autocomplete support
- •Documentation: Auto-generated types serve as living documentation for XML structures
Pro Tips
- •Paste XML and it auto-validates - conversion triggers when valid XML detected
- •Type inference detects numbers, booleans, and ISO dates automatically
- •Nested elements generate separate interfaces ordered dependencies-first
- •Repeated elements become array types: tags: string[] or items: Item[]
Most Popular
Most users enable interface, export, type inference, merge attributes, and use Type[] syntax
When to Use This Tool
Generate TypeScript types from XML API responses or WSDL schemas for building type-safe SOAP/REST API clients. Convert XML API documentation or example responses to TypeScript interfaces for compile-time type checking, IDE autocomplete, and reduced runtime errors. Perfect for integrating with legacy SOAP services or XML-based APIs in modern TypeScript applications.
Recommended: API Integration
Transform XML schemas or data structures into TypeScript interfaces for strongly-typed data models. Use generated types with libraries like Zod or io-ts for runtime validation. Ideal for parsing XML configuration files, processing XML data feeds, or building data transformation pipelines with full type safety and IntelliSense support.
Recommended: Type Safety
Modernize legacy XML-based systems by generating TypeScript types for gradual migration to type-safe code. Convert XML DTDs, XSDs, or example documents to TypeScript interfaces that can be used with xml2js or similar parsers. Enables incremental adoption of TypeScript in projects dealing with XML data while maintaining backward compatibility.
Recommended: Legacy Systems
How It Works
Paste or type your XML document into the input field
Tool automatically validates XML using browser's DOMParser API
Green checkmark appears when XML validation passes successfully
Click 'Convert to TypeScript' to start conversion
XML is recursively parsed into object structure with attributes and text
Type inference analyzes text values to determine TypeScript types
Numeric strings → number, 'true'/'false' → boolean, ISO dates → Date
XML attributes merged into interface properties (or nested if option disabled)
Repeated XML elements detected and converted to array types
Nested elements generate separate interface definitions
Interfaces formatted with proper indentation and code style options
Property names converted to camelCase (or preserved if option enabled)
Interfaces ordered with nested types first, root interface last

Frequently Asked Questions
What is the difference between interface and type in TypeScript?
Interfaces and types are similar in TypeScript, but interfaces are generally preferred for object shapes. Interfaces can be extended and merged, while types are more flexible for unions, intersections, and primitives. For generated code from XML, interfaces are recommended as they represent object structures and can be easily extended if needed.
How are XML attributes converted to TypeScript properties?
With 'Merge Attributes' enabled (recommended), XML attributes become regular interface properties with inferred types. For example, <user id='123' verified='true'> creates properties id: number and verified: boolean. The tool automatically infers types from attribute values when type inference is enabled.
What does the optional (?) modifier do?
The optional modifier (?) makes properties optional in TypeScript, meaning they may or may not be present on the object. When 'Make Optional' is enabled, all properties get the ? modifier: name?: string. This is useful for XML with optional elements or when you want flexibility in the generated types.
How are repeated XML elements handled?
Repeated XML elements (multiple children with the same name) are automatically detected and converted to array types. Simple repeated elements become value arrays like tags: string[]. Complex repeated elements generate separate interfaces: items: Item[] where Item is the interface for each element's structure.
Why use Type[] vs Array<Type> syntax?
Both syntaxes are equivalent in TypeScript. Type[] is more concise and commonly used for simple cases, while Array<Type> is preferred for complex generic types. The tool defaults to Type[] (brackets) but you can toggle to Array<Type> syntax. Choose based on your team's code style preferences.
How is type inference handled for XML text content?
When 'Infer Types' is enabled, the tool analyzes text values to determine types: numeric strings become number, 'true'/'false' become boolean, ISO 8601 dates become Date, and everything else is string. When disabled, all values default to string type. This provides flexibility based on whether you want strict typing or looser string-based types.
Can I convert XML with namespaces?
Yes! The tool processes XML with namespaces by parsing element names as-is. Namespace prefixes are included in property names (e.g., ns:user becomes nsUser when camelCase conversion is enabled, or 'ns:user' if preserving keys). For cleaner types, consider preprocessing XML to remove namespace prefixes if they're not needed.
Is my XML data secure using this tool?
Absolutely! All XML parsing and TypeScript generation happens entirely in your browser using JavaScript and the DOM Parser API. Your XML is never sent to any server, uploaded anywhere, or stored remotely. Everything runs 100% locally client-side, ensuring complete privacy for sensitive XML documents like API schemas or proprietary data structures.
