Type generation

Turn any document into ready-to-paste type definitions for 9 languages.

Targets

Pandia generates types for nine targets:

Target	Output
TypeScript	`export interface`
Rust	Derived `struct`
Go	`struct` with JSON tags
Kotlin	`data class`
Python	`@dataclass`
PHP	`final readonly class`
Java	POJO with getters and setters
Zod	`z.object(...)` schema
JSON Schema	Draft 2020-12

How it works

Open the Types panel in the sidebar, pick a target, and copy the output. Generation samples the document and infers the shape: where a field's values are missing in some objects, or are null, Pandia marks that field optional or nullable in the generated type.

Example

Given a small JSON object:

{
  "id": 42,
  "name": "Ada",
  "email": null,
  "active": true
}

The TypeScript target produces:

export interface Root {
  id: number;
  name: string;
  email: null;
  active: boolean;
}

Not configurable, by design

Note — the output is opinionated. There are no naming-convention settings or option toggles — each language uses fixed, idiomatic casing, and optionals are inferred for you rather than configured. Pick a target, copy, paste.
