Features

Multiple Input Methods

You can input all things by uploading a file, pasting the hex string or base64 string.

Display in Human-readable Format

This tool uses a table to display tags, field ids, wire types and the values of each fields in the given message.

It will try to recognise nested messages (even without the .proto file) and display them in a tree-like structure.

Make Use of .proto File

If you provide a .proto file and specify the message type, the viewer will display field names and enum values. You can even hover over the field name to see the field's original definition.
