TypeMorph for VS Code
Convert JSON, YAML, OpenAPI, and JSON Schema into 160+ output formats — without leaving your editor.
Features
- Convert any schema — paste JSON or YAML, pick a target format, get code instantly in a side panel
- 160+ output formats — TypeScript, Zod, Go, Rust, Python, Prisma, SQL, React Props, and more
- Schema Quality Score — grades your schema A–F and flags issues (missing types, naming inconsistency, deep nesting)
- OpenAPI & JSON Schema aware — automatically detects and parses multi-component specs
- 100% local — no network requests, no API keys, no data leaves your machine
Usage
Convert a schema

- Output appears in a side panel with syntax highlighting
You can also select a portion of a file and convert just that selection.
