Ui Path Queue

I am using orchestration queue with name “Demo”. in uipath studio i am coppy all the excel data into add queue item. first time it adds all the items into queue but when 2nd time i run the job with new fields data and some previous one it also adds all data into orchestrator queue without removing duplicate can someone guide me for this ?

That’s is not handled by default in orchestrator, you ahve to handle that in code.

How by maintaining it in separate excel sheet?

Is there any way in uipath we put certain transaction into the question with different dates and want to execute these transaction in the question on mention transaction date.
