For traversing 70,000 rows(using for loop), my macro is taking a lot of time to give output comment as per various conditions(if statement). Please help me improve my approach.I am working on around 70,000 rows and my code is taking a lot of time to run. Please see the attachment image that depicts how data looks. Can someone please guide me with a better approach here?
