Inspect and debug your Protocol Buffer binaries

This tool attempts to decode Protocol Buffer binaries into JSON for easy analysis in a human-readable format. You can optionally enable debug and extended information to facilitate data exploration and debugging.

With no options selected, output is nearly identical to "protoc --decode_raw" except in JSON format. Fields with the same ID in a given scope are placed in an array.

Documentation on Protocol Buffers specifications can be found here: Specs, Numeric Types

Samples: Test 1, Test 2, Test 3

More Samples: String Discovery Option (test with option on/off)

Step 1: Upload Protobuf binary file
