Convert Map values to relevant data type

In protobuf, I am using a map field -> map<string, google.protobuf.Any>. After compilation is getting converted into ma[string]*anypb.Any ,Now if I want to pass this to a template renderer engine, I am converting it manually in many places. Maybe we can have these types of conversion utils for the map also.

Can you give an example of the conversion you're doing please ?

Anyway, it seems too specific to the protobuf library.
