Hi @wachid
You need to set the column value to null when excel column is empty or blank. You need to write an expression to work it:
if(empty(items('Apply_to_each')?['Received']),null,items('Apply_to_each')?['Received'])
I have assumed that you are creating an item in a loop 'Apply to each'.
If this helps & solves your problem, please remember to give a 👍 and accept my solution as it will help others in the future.
Thanks
