What is YAML to TypeScript Converter?
Need to generate TypeScript interfaces from your YAML (YAML Ain't Markup Language) data? This tool does that instantly. Perfect for creating type-safe TypeScript code from YAML configs, API schemas, or data structures. Generate interfaces, types, and type definitions automatically.
According to TypeScript documentation, type definitions make code more maintainable and catch errors at compile time. Our converter analyzes your YAML structure and generates proper TypeScript interfaces. First, validate your YAML using our YAML Validator, then convert it to TypeScript. You can also convert from other formats like JSON to YAML first if needed.
Everything happens in your browser – your YAML never leaves your computer. Convert, download, and use your TypeScript interfaces right away.
What Makes This Tool Different
Automatic Interface Generation
We analyze your YAML structure and automatically generate TypeScript interfaces. Nested objects become interfaces, arrays become typed arrays, everything gets proper types.
Type Safety
Generated TypeScript code includes proper types, making it easier to catch errors before runtime. TypeScript's compiler will help you find issues early.
Validation Built-In
We validate your YAML first, so you know the conversion will work. Invalid YAML gets caught before conversion starts. Use our YAML Validator separately if needed.
File Upload Support
Got a big file? Just upload it. Works great for converting those massive YAML configs or data files without copy-pasting.
Download TypeScript
One click to download your TypeScript file. Drop it into your TypeScript project and start benefiting from type safety. Perfect for API clients or config type definitions.
Clean Code Output
The generated TypeScript code is clean and well-formatted. Interfaces are properly named, types are inferred correctly, and the code is ready to use.
How It Works
Paste or Upload YAML
Paste your YAML into the left editor, or click "Upload" to load a file. The YAML should be valid – use our YAML Validator first if you're not sure. You can also click "Sample" to see an example.
Automatic Conversion
As soon as you paste, the converter processes your YAML and displays the TypeScript interfaces on the right. Nested structures become interfaces, keys become properties, and arrays become typed arrays.
Download or Copy
Click "Download" to save the TypeScript file, or "Copy" to copy it to your clipboard. The TypeScript code is ready to use in your project. Drop it into your TypeScript project and start using type-safe code.
When You'd Actually Use This
API Type Definitions
Generate TypeScript interfaces from YAML API schemas. Create type-safe API clients with proper type definitions. Perfect for OpenAPI or other YAML-based API specs.
Config Type Safety
Create TypeScript types from YAML config files. Ensure type safety when reading configs in TypeScript applications. Catch config errors at compile time.
Code Generation
Generate TypeScript code from YAML data structures. Perfect for creating type definitions, interfaces, or type-safe data models from YAML schemas.
Type-Safe Development
Add type safety to YAML-based workflows. Convert YAML configs to TypeScript types for better IDE support, autocomplete, and error checking.
Common Questions
Is my YAML data stored?
Nope. Everything happens right in your browser. Your YAML never leaves your computer – we don't even see it.
How are nested structures handled?
Nested YAML structures become nested TypeScript interfaces. Keys become interface properties, and nested objects become separate interfaces or inline types.
Are types inferred correctly?
We do our best to infer types from your YAML structure. Strings, numbers, booleans, arrays, and objects are all handled. You may need to manually adjust some types for complex cases.
Can I use the generated TypeScript?
Yes. The generated TypeScript code is valid and ready to use. Drop it into your TypeScript project and start using it. You may want to review and refine the types for your specific use case.
What about optional properties?
The converter generates interfaces based on your YAML structure. If you need optional properties, you may need to manually mark them with `?` in TypeScript after conversion.
Does it work with large YAML files?
Yep. Since everything happens in your browser, it depends on your device. Small to medium YAML structures convert instantly. Really huge structures might take a few seconds.
Other YAML Tools You Might Need
Conversion is just one YAML task. Here are other tools that work well together:
