To be fair is mainly just repeating bits.

to stop partial matches use =MID(A2,AGGREGATE(15,6,SEARCH(Words&" ",A2),1),SEARCH(" ",A2,AGGREGATE(15,6,SEARCH(Words&" ",A2),1))-AGGREGATE(15,6,SEARCH(Words&" ",A2),1)).

The search part (SEARCH(Words&" ",A2),1) finds the word, the space finds the whole whole and not partials

aggregate 15 is the same as small but aggregate can deal with arrays, the 6 is telling it to ignore errors (i.e not matches). So if there are 2 matches this will find only the first one

the first AGGREGATE finds the number of the first character of the word we are looking for. (26)

the second AGGREGATE finds the number of the first space after the word we are looking for (31)

the third is just a repeat of the first AGGREGATE.

All this in the MID makes it Mid(a2,26,31-26)

Hope it helps
