Is there a method without using macro or script, to get this result?
Bus Line L1 L2 L3 L4 Result
Stops
1 X X L2,L4
2 X L4
3 X X L1,L3
I need to concatenate COLUMN'S NAME for each "X" on rows.
In F2 enter the array formula:
=TEXTJOIN(",",TRUE,IF(B2:E2="X",$B$1:$E$1,""))
and copy down:
Array formulas must be entered with Ctrl + Shift + Enter rather than just the Enter key. If this is done correctly, the formula will appear with curly braces around it in the Formula Bar.
