How to use array formula to return an array of sums in Excel

Question

eg, we have

 1  2  4
 3  4  5
 4  5  5
 2  4  5

I would like a array formula that returns an ARRAY = {7,12,14,11} Note it is not text, it i

Answer 1

I think this evaluates to the required array and could be extended to larger ranges:

=MMULT(A1:C4,TRANSPOSE(COLUMN(A1:C4)^0))

Answer 2

When your matrix starts at A1 you can use:

=VERKETTEN("{";SUMME(A1:C1); ",";SUMME(A2:C2);",";SUMME(A3:C3);",";SUMME(A4:C4);"}")

This is of course for the german version. But "SUMME" should be SUM and "VERKETTEN" should be CONCATENATE. I'm sure you will find it in the help.

then it will be:

=CONCATENATE("{";SUM(A1:C1); ",";SUM(A2:C2);",";SUM(A3:C3);",";SUM(A4:C4);"}")

Even shorter:

="{"&SUM(A1:C1)&","&SUM(A2:C2)&","&SUM(A3:C3)&","&SUM(A4:C4)&"}"

For more you might need to use scripts that can handle loops etc.
