I have two tabs of data from different reporting months with ~1800 lines sorted in different ways. I am trying to find the same Project Numbers (column A) from each tab and calculate the difference in Next Year Forecast (column AJ - December 2022 tab) and Forecast (column AI - July 2023 tab). Screenshots below for reference:

Excel Facts

Which lookup functions find a value equal or greater than the lookup value?
MATCH uses -1 to find larger value (lookup table must be sorted ZA). XLOOKUP uses 1 to find values greater and does not need to be sorted.
