You can use SUBTOTAL or AGGREGATE function to sum visible rows but Excel doesn't provide the facility to sum only visible columns. Look below. Columns B and D are hidden. Hence, our function should sum up only A, C, E and F. G2 has the formula =SUM(A2:F2)
If you hide the columns, the sum stays the same whether columns are hidden or visible.
Unfortunately, Excel doesn't provide any native functionality to accomplish this. This will have to be done through a VBA function. We will write a VBA function "SumVisCols" which can be called like =SumVisCols(A2:F2)
(You can give any range not only A2:F2)
