Let’s say we have text in all of the following cells (but in cell B1 we only have one word) :

A1 B1 C1

A2

A3

A4

A5

I would like to know what’s the formula to find :

If the word in cell B1 appears in one of the cell of A1:A5 (but each cell from A1 to A5 contain more than one word) then if it’s true = C1

I hope it's clear enough

Thanks in advance
