I have a spreadsheet of many tens of thousands of rows and wish to prune the data to make it more manageable.
It is the output of a monitoring system that spits out a row of data every 15 minutes.
What I want to do is count how many rows of data there are at (say) a quarter past the hour, up to an end date (say, 1/1/23). I can use this in my macro then for various purposes.
I know how to use MINUTE() to get the minute value into a new column and then use COUNTIF on the new column but I don't want to do that as I will have to check through several macros to make sure they are addressing the correct columns.
Does anyone know how to count the occurrences of data at 15 minute intervals please?
