In those rare instances where I need to use indirect I sometimes point the
column reference to this, for example
=IF(QUOTIENT(COLUMN($C$2)-1,26)=0,"",CHAR(QUOTIENT(COLUMN($C$2)-1,26)+96))&CHAR(IF(MOD(COLUMN($C$2),26)=0,26,MOD(C OLUMN($C$2),26))+96)
which will return C, but change to D if a column is inserted.
Is there a shorter way to do this, some formula that will change back the 3
result of =COLUMN($C$2) back into a C?
(Forgive me for showing QUOTIENT(COLUMN($C$2)-1,26), I've already learned
from seeing Bob Phillips posts that INT((COLUMN($C$2)-1)/26) requires less
typing.)
