Mz Mz Protobuf Parser szerző: Muuuz

Mz Mz Protobuf Parser is a lightweight, developer-focused tool that allows you to decode and inspect Protocol Buffer (protobuf) binary data without requiring the original .proto schema definition.

This extension is especially useful when working with unknown APIs, reverse engineering network traffic, debugging binary payloads, or analyzing data formats where the schema is unavailable or incomplete.

Simply paste your data in one of the supported formats — hexadecimal, Base64, or raw bytes — and the parser will automatically detect the encoding, decode it, and present a structured, human-readable view of the message.

Key features
Schema-free decoding
Parse protobuf messages without needing .proto files.
Automatic format detection
Supports Base64, hex (with or without spaces/0x), and raw binary input.
Structured field visualization
Displays field numbers, wire types, and decoded values in an expandable tree view.
Nested message support
Automatically detects and recursively parses embedded protobuf messages.
Smart data interpretation
Attempts to interpret fields as:
integers (varint, signed/unsigned)
floating point values (32-bit / 64-bit)
UTF-8 strings
raw byte arrays
Interactive exploration
Expand and collapse nested fields to explore complex payloads easily.
JSON export
Copy the parsed structure as formatted JSON for further analysis or debugging.
Error handling
Clear feedback when invalid or malformed data is provided.
Use cases
Debugging protobuf-based APIs
Inspecting network traffic (e.g. from web apps or mobile apps)
Reverse engineering undocumented services
Learning and understanding protobuf wire format
Analyzing GIS, telemetry, or binary data streams
