Hi all and thanks for any help given. Due to confidentiality I can't share exact details or images but I hope to explain well enough to get help. I have 50,000+ rows of data, new data every hour from multiple devices at multiple locations, and I need to find averages for the separate devices over separate days. I have location name in column A, device name in column B, and date/ time in column C, results in column D. An example of the time format would be; 9/7/2022 7:00:00 PM. My hope was to type a location into E2, a device name into F2, and a date, e.g. 9/7/2022, into G2 then have a formula in H2 search and average all D columns in rows that match all three of those. Is that possible or is there a better way of doing this?
