Return non-zero data and associated row header from an array

[MrNal]

I will be grateful for help with the following

I have an array in the following manner:

31/01/2018 28/02/2018 31/03/2018 30/04/2018 31/05/2018 30/06/2018......
First 120 0 145 0 0 20
2nd 0 10 0 6 0 0
.
.

Using a formula I will like to return any non-zero value with their associated date e.g. for First I will like to return the following

120 31/01/2018
145 31/03/2018
20 30/06/2018

The numbers in the array are derived by formula and I can't use traditional index/match because I don't know the date that the non-zero will occur beforehand. I know the column headers that will have the non zero- values

Will be grateful for help with formula that can achieve what I want.

Many thanks.

For this example, let's assume that A1:G3 contains the data. For the First, try...

I2:

=COUNTIF(B2:G2,">0")

J2, copied down:

=IF(K2<>"",INDEX($B$2:$G$2,MATCH(K2,$B$1:$G$1,0)),"")

K2, confirmed with CONTROL+SHIFT+ENTER, and copied down:

=IF(ROWS(K$2:K2)<=$I$2,INDEX($B$1:$G$1,SMALL(IF($B$2:$G$2>0,COLUMN($B$2:$G$2)-COLUMN($B$2)+1),ROWS(K$2:K2))),"")

Note that the formulas in Column J will only return an empty string ("") until the formulas in Column K have been entered.

Hope this helps!

A slightly different version.
I1 and K1 manually entered.
Formulas in I2:J2 copied down for as many rows as there are dates in the data section (so down to row 7 for this sample)
Then copy I2:J7 to K2 etc

Non-Zero

Many thanks for taking the time to come up with potential solutions.

Although both suggestions do work to a point, they don't quite work well for my purpose. I need the output to be in be in single colum as I need to then manipulate the data for another purpose. The real struggle is to get the date as I can get the row reference (first 2nd easily). It will be then easy to get data in the array (120,145,20 etc) as I can use index/match to retrieve this once I have a formula return the date.

Will be grateful for suggestions.

Is this what you want then?
