Hi,

This is the data i have in range A1:C7 - headings are in range A1:C1

Docket NoTransporter NameDel.
126341335​
0M LOGISTICS LIMITED
1227061646​
126341335​
0M LOGISTICS LIMITED

My objective is to keep one row for each Docket and Transporter combination and create as many columns as there are Del.'s for that docket and transporter combination. I am trying to solve this problem by using the BYROW() and LAMBDA function. This is what i have tried so far

In cell E2, i entered this formula

=UNIQUE(A2:B7)

In cell G2, I entered this formula but i received the #CALC! error

=BYROW(INDEX(E2#,,1),LAMBDA(r,TRANSPOSE(FILTER($C$2:$C$7,$A$2:$A$7=r))))

I'd like the formula written in cell G2 to spill over to the rows and columns automatically.

What mistake have i committed in the formula written in cell G2? How can i modify the formula so that it spills over to the rows and columns automatically?

Thank you for your help.
 

Excel Facts

Which Excel functions can ignore hidden rows?
The SUBTOTAL and AGGREGATE functions ignore hidden rows. AGGREGATE can also exclude error cells and more.
Sort by date Sort by votes
The BYROW function can only be used with functions that return 1 record per row (this is explained in the errors section of the function help page).

With a formula you would be able to spill to columns but would need to fill the rows using the traditional autofill method.
Excel Formula: 
=TRANSPOSE(FILTER($C$2:$C$7,$A$2:$A$7=E2))
Power query is another way that it can be done although I would not be able to take you through the necessary steps at the moment (no desktop version of excel to hand).

I'm assuming then that not all Transporter names will be the same, unlike your sample. Therefore I have changed one of those values for my sample.
I'm also assuming that you have all the latest functions available.

See if this is any use. It may fail if your data is large since TEXTJOIN has a character length limit.

Actually, I don't think that I have. My suggestion would fail if two or more Docket No/Transporter Name combinations share the same Del numbers.
Example

Might just have the UNIQUE function in the wrong place?
Not highly tested though.

Hi
What about =IFERROR(DROP(REDUCE(0,UNIQUE(A2:A7),LAMBDA(x,y,VSTACK(x,TRANSPOSE(FILTER($C$2:$C$7,$A$2:$A$7=y))))),1),"")
