local exporter as <file_name>.proto file

[skmonjurul]

Is .proto file supported by exporter?

receivers:
otlp:
protocols:
grpc:

exporters:
file:
path: ./sampleProto.proto

service:
extensions: []
pipelines:
traces:
receivers: [otlp]
exporters: [file]

Is this valid? Because I am not getting any error and sampleProto.proto file is getting created but the data is in json format.

By ".proto" you mean binary proto, not the proto definition :)

See https://github.com/open-telemetry/opentelemetry-collector/discussions/2457 where we discussed exactly this.
