If you have someone’s name in a cell and want to automatically extract initials, you can use LEFT, MID and FIND.

As always when working with text cells, you can wrap with UPPER, LOWER or PROPER.

A B < B function >
1 Joe Bloggs JB =LEFT(A1)&MID(A1,FIND(” “,A1)+1,1)
2 joe bloggs JB =UPPER(LEFT(A2)&MID(A2,FIND(” “,A2)+1,1))

 

I also found online  a funtion to manage three names – seems long so I imagine there is an easier way to do it, but it works:

A B < B function >
1 Joe John Bloggs JJB =IF(LEN(A1)-LEN(SUBSTITUTE(A1,” “,””))=0,LEFT(A1,1),IF(LEN(A1)-LEN(SUBSTITUTE(A1,” “,””))=1,LEFT(A1,1)&MID(A1,FIND(” “,A1)+1,1),LEFT(A1,1)&MID(A1,FIND(” “,A1)+1,1)&MID(A1,FIND(” “,A1,FIND(” “,A1)+1)+1,1)))
