This online tool allows users to convert Google protobuf files, which are a compact, binary format used by Google for serializing structured data, into JSON format. JSON is a widely-used, human-readable data interchange format that is easy for humans to read and write. With this tool, users can upload a Google protobuf file and view a JSON representation of its contents, as well as the structure of the JSON data. The tool also has a protobuf file reader function, which allows users to view and explore the contents of a protobuf file in a user-friendly interface. This can be useful for debugging and understanding the data contained in a protobuf file. The tool can be accessed from any web browser and supports real-time conversion and reading of Google protobuf files.
