I want to do Pareto analysis, So I have column A which is ordered Z->A. I want to fill the column B as it is the sum of previous records in A. just like the example:
How Can I rewrite the B formula using ARRAYFORMULA function?
try in B2:
=ARRAYFORMULA(IF(A2:A="";;SUMIF(ROW(A2:A); "<="&ROW(A2:A); A2:A)))
