Spill Sum formula in column excel

Question

I have two sheets, one called All Project Net Profit with row data spilling across the rows with month/year dates and the Net Profit total in row 13. The following is a sample of the data:

2017	2017	2017	2017	2017	2018	2018	2018	2018	2018	2018	2018	2018
Aug-17	Sep-17	Oct-17	Nov-17	Dec-17	Jan-18	Feb-18	Mar-18	Apr-18	May-18	Jun-18	Jul-18	Aug-18
-22596	77104	81604	81604	81604	81604	81604	81604	81604	81604	81604	81604	81604

The other sheet called Yearly Net Profit calculates the yearly Net Profit using the formula =SUM((--TEXT('All Projects Net Profit',$I$13#,"£0,00")*(1*A2=--'All Projects Net Profit'!$I$1#))) pasted in to B2 .

For now I have manually copied the formula down the columns but is there a way to make it spill for the amount of entries in Column A?

Sample data for the Yearly Net Profit sheet:

Year	Net Profit
2017	299320
2018	979248
2019	943813
2020	-206450
2021	-763368

Answer 1

Using BYROW:

=BYROW(  A2:A6,
 LAMBDA( x,
SUM((--TEXT('All Projects Net Profit'!$I$13#,"£0,00")*(--x=--'All Projects Net Profit'!$I$1#)))))

You first declare the range you want to use your formula: A2:A6 ;

Then you use LAMBDA to name that byrow-range: x ;

Then use your "regular" formula and replace the A2 from your original formula, that you want to do byrow with x .

Done.
