Paste your Python classes or data structures that you want to convert to Protocol Buffer format. Our tool intelligently analyzes your Python code structure and generates corresponding protobuf schemas.

Whether you're working with simple dataclasses, complex nested classes, or existing Python models from your applications, the converter handles various Python code patterns and transforms them into efficient protobuf definitions for gRPC services and microservices communication.

Select the Protocol Buffer output format that best suits your development needs. Each format serves different purposes in modern application architectures.

The proto schema format generates complete .proto files ready for compilation, while text format provides human-readable protobuf data for testing and debugging. Binary format offers compact, efficient data encoding perfect for microservices communication.

Copy or download the generated protobuf definition and integrate it into your development workflow. The generated schema files are ready for immediate use in your applications and deployment pipelines.

The protobuf schemas work perfectly in containerized environments like Kubernetes and Docker-based deployments. You can use them to define service contracts, generate client libraries, and ensure consistent data structures across distributed systems.

Compile your generated .proto file using the Protocol Compiler (protoc) to generate code for your target programming languages. This creates the client and server stubs needed for your application.

The compiled code integrates seamlessly into API-first development workflows, enabling strong typing and automatic serialization across different services and programming languages in your distributed system.

# Save as user.proto and compile
protoc --python_out=. user.proto

# Use in your Python project
import user_pb2
user = user_pb2.User()
user.id = 123
user.name = "John Doe"
