YAML to TypeScript POJO Generator

Paste YAML configuration or API samples and generate TypeScript interfaces in the browser. Same workflow as JSON-to-TypeScript tools, but YAML-first for Kubernetes manifests, CI files, and OpenAPI-style snippets.

Name the root interface, load a sample or your file, then copy or download types.ts. Parsing and type generation stay on your device.

How it works

YAML is parsed into plain JavaScript values, then converted into TypeScript declarations using the same structural inference approach as our JSON to TypeScript generator. Nested objects become nested interfaces; arrays infer element types from the first element when possible.

Frequently Asked Questions

Does this support multi-document YAML?

Only the first document returned by the parser is used. Split files or merge documents if you need several roots.

What happens for YAML timestamps or non-JSON values?

Timestamps and other special scalar types are parsed as JavaScript values. If inference looks wrong, convert those nodes to strings in YAML or use JSON-compatible YAML for best results.

Can I use this for strict runtime validation?

Generated output is for static typing only. Pair it with Zod, io-ts, or JSON Schema if you need runtime checks.
