If I have values in column A in a spreadsheet starting from A1 to A5 as for example 1, 2, 3.5, 4, 6 and I need to extract all values less than 5 in a new column, what is the best method? And how do I set the auto extraction if the value 5 is in for example in cell C1. That is mean when I changed the value in C1 the values extracted in the new column will changed according to the new value in C1.
