XML to TypeScript
Generate TypeScript interfaces from XML structure — bridge legacy XML APIs to a modern TypeScript codebase.
Drop an XML file
we'll infer TypeScript interfaces from its structure
When your TypeScript app talks to a legacy XML API, you need typed shapes for the data. Converterzilla's XML to TypeScript generator infers types from a sample XML document — primitives become string/number/boolean, repeated elements become arrays, nested elements become nested interfaces — and emits a complete .ts file.
How to use XML to TypeScript in your browser
- Drop or paste a sample XML. Use a representative example with all the fields you care about.
- Set the root interface name. Defaults to Root — change if you want something more meaningful like ApiResponse.
- Click Generate. Interfaces appear in the output area, ready to drop into your codebase.
Why use Converterzilla for XML to TypeScript
Smart type inference
Numbers stay numbers, booleans stay booleans, the rest stays string. Repeated elements become array types.
Nested interfaces
Each nested element gets its own interface. Names are PascalCase'd.
Browser-only
Your XML never reaches a server — useful when the structure is internal API data.
Frequently asked questions about XML to TypeScript
Yes. Attributes appear as fields prefixed with @ — though we strip the @ in the field name to keep them valid TS identifiers.
Single-sample inference can't detect unions. If you have a field that's sometimes a string and sometimes an object, you'll need to manually merge the inferred types.
Not yet — output is interface declarations only. Type guards are on the roadmap.
