How to filter multiple columns data to one column in Excel?

Question

I have two columns data contain "#N/A" and "Data", but I have not any idea to filter/combine to one column.

So see below pic, How to combine(or filter) multiple columns to D column?

Can give me a hint to solve?

Answer 1

Assuming that there is only one "wanted" value in a row and assuming that a row can contain all unwanted #N/A values, you can use this array formula, which must be confirmed with Ctrl-Shift-Enter, starting in row 1, then copied down

=LOOKUP(2,1/NOT(ISNA(A1:C1)),A1:C1)
