Hi @sudharsan1985,
I think I did not explain myself well.
In the video that you suggested, I understand how not to repeat items or obtain unique values, but it is from a table. But I want to know how to create a flow that can review the values ​​of the Excel row and see if they exist in the Sharepoint List and then Create new Items from Excel to Sharepoint and not create repeated rows.
You can help me with this.
