Deleting Rows based on hierarcy
 

Bear with me - new to macros so I am not sure if this can even be done. I
have a spreadsheet of information (15k rows) and there are numerous rows
where all the info is the same except ithe date in one column is different. I
would like to write a macro that looks at the rows of exact duplicates except
for the date and deletes the row that has the lower date keeping the most
recent valued row. Is this possible?
