Make public form in Excel (8)
I believe the answer is:
outclass
'excel' is the definition.
(related meaning)
'make public form' is the wordplay.
'make public' becomes 'out' (I've seen this in another clue).
'form' becomes 'class' (synonyms).
'out'+'class'='OUTCLASS'
'in' is the link.
(Other definitions for outclass that I've seen before include "Top" , "Trump" , "Be far superior to (someone)" , "Surpass greatly, be in a superior category" , "put in the shade" .)
