My does exactly what I want it to. However, being relatively new to VBA I feel it could be a lot more efficient - namely I think I have overused loops and worksheet functions which are slowing it down. At the moment it takes around 3 minutes for ~15k rows of data.



At the moment it's more of a combination of separate steps joined together so it doesn't flow nicely, rather for each steps it iterates through every row which, while it gets the job done, is frustratingly inefficient.



At the moment I am trying to remove the loops perhaps using Range objects instead, but I would really appreciate any pointers in the right direction.

      My does exactly what I want it to. However, being relatively new to VBA I feel it could be a lot more efficient - namely I think I have overused loops and worksheet functions which are slowing it down. At the moment it takes around 3 minutes for ~15k rows of data.



      At the moment it's more of a combination of separate steps joined together so it doesn't flow nicely, rather for each steps it iterates through every row which, while it gets the job done, is frustratingly inefficient.



      At the moment I am trying to remove the loops perhaps using Range objects instead, but I would really appreciate any pointers in the right direction.
