Instant JSON to Type Converter (TypeScript, Go, Rust, Python)

Stop manually typing interfaces for your API responses. Pixedra’s JSON Converter instantly generates type-safe definitions for your projects. Whether you need TypeScript Interfaces, Golang Structs, or Python Pydantic models, simply paste your JSON and get clean, production-ready code.

Unlike other converters, this tool runs 100% Client-Side. Your proprietary API data and sensitive JSON payloads never leave your browser. It is safe to use for production data.

How to Generate Types from JSON

  1. Paste JSON: Copy your API response or JSON object into the left "Input" panel.
  2. Select Language: Click the tab for your desired language (TypeScript, Go, Rust, or Python).
  3. Copy Code: The tool instantly parses the data and displays the generated code on the right. Click the "Copy" icon to use it in your editor (VS Code, IntelliJ).

Why Use Pixedra?

  • Privacy First

    We use local JavaScript execution. No server logs your data.

  • Smart Type Detection

    We differentiate between integers and floats (essential for Go/Rust).

  • Nullable Handling

    If a field is null in your JSON, we automatically mark it as optional (e.g., string | null or Option<String>).

  • Works Offline

    Once the page loads, you can use it without an internet connection.

Supported Conversions

1. JSON to TypeScript Interface

Automatically detects types (string, number, boolean) and handles Nested Objects. Generates clean interface definitions compliant with TS strict mode. Perfect for React, Next.js, and Node.js developers.

2. JSON to Go (Golang) Struct

Generates idiomatic Go structs with standard json tags. It automatically handles capitalization conventions (PascalCase for exported fields) so you can unmarshal JSON in Go instantly.

3. JSON to Rust (Serde)

Creates Rust structs compatible with the Serde serialization framework. Automatically maps JSON types to Rust primitives (String, i64, bool, Option<T>).

4. JSON to Python (Pydantic/Dataclass)

Converts JSON keys into Python class definitions. Ideal for FastApi and Django developers looking to strictly type their backend responses.
