We support CR, LF or CRLF. __Text__   38b0852c-9673-4230-9b58-e0a336a348fe 4175f9fa-83db-4da7-95d6-62d1f2296c56 689626da-ebe3-4e01-a505-e36b09acae33 7f9e25cd-119b-44f3-8351-5c95ce3f8009 80b7407f-abee-42c2-86c2-00b49241c214 8d553fa4-1173-4263-b9b2-4ed33b6a5d60 964cf285-ee6a-4161-a291-3dbeda009a37 00026568-4479-4768-8aa1-42af920fefe5 000857c8-da88-4fd3-b853-1d919f982ff0 000c1019-f6cf-49d8-acc7-83ff7b1883f2   Duplicates will be removed during the matching process. ## Event Format You can optionally specify one or more events for each device. To specify an event put a comma after the device identifier and then the text of the event name. You may use any event names that make sense to you, and they will become available in the Audience Marketplace after the upload is processed. Note there are three "special" event names that are treated specifically in the Audience Marketplace: - impression - click - conversion If generating files from a platform which tracks these advertising-related events, please try to use these event names if possible. __Text__ 38b0852c-9673-4230-9b58-e0a336a348fe,impression 4175f9fa-83db-4da7-95d6-62d1f2296c56,impression 689626da-ebe3-4e01-a505-e36b09acae33,impression 7f9e25cd-119b-44f3-8351-5c95ce3f8009,impression 80b7407f-abee-42c2-86c2-00b49241c214,impression 8d553fa4-1173-4263-b9b2-4ed33b6a5d60,impression 964cf285-ee6a-4161-a291-3dbeda009a37,impression 00026568-4479-4768-8aa1-42af920fefe5,impression 000857c8-da88-4fd3-b853-1d919f982ff0,impression 689626da-ebe3-4e01-a505-e36b09acae33,click 000c1019-f6cf-49d8-acc7-83ff7b1883f2,impression 964cf285-ee6a-4161-a291-3dbeda009a37,click 689626da-ebe3-4e01-a505-e36b09acae33,conversion     Every line does not have to specify an event.
