I posted it so that you can easily see the structure of the formula,
to extend it if you need to. Just keep copying the IFs and change the
numbers in sequence. This will do the complete alphabet:
=IF(LEN(A1)<1,"",MID(A1,LEN(A1),1))&IF(LEN(A1)<2,"",MID(A1,LEN
(A1)-1,1))&IF(LEN(A1)<3,"",MID(A1,LEN(A1)-2,1))&IF(LEN(A1)<4,"",MID
(A1,LEN(A1)-3,1))&IF(LEN(A1)<5,"",MID(A1,LEN(A1)-4,1))&IF(LEN(A1)
<6,"",MID(A1,LEN(A1)-5,1))&IF(LEN(A1)<7,"",MID(A1,LEN(A1)-6,1))&IF(LEN
(A1)<8,"",MID(A1,LEN(A1)-7,1))&IF(LEN(A1)<9,"",MID(A1,LEN(A1)-8,1))&IF
(LEN(A1)<10,"",MID(A1,LEN(A1)-9,1))&IF(LEN(A1)<11,"",MID(A1,LEN
(A1)-10,1))&IF(LEN(A1)<12,"",MID(A1,LEN(A1)-11,1))&IF(LEN(A1)<13,"",MID
(A1,LEN(A1)-12,1))&IF(LEN(A1)<14,"",MID(A1,LEN(A1)-13,1))&IF(LEN(A1)
<15,"",MID(A1,LEN(A1)-14,1))&IF(LEN(A1)<16,"",MID(A1,LEN(A1)-15,1))&IF
(LEN(A1)<17,"",MID(A1,LEN(A1)-16,1))&IF(LEN(A1)<18,"",MID(A1,LEN
(A1)-17,1))&IF(LEN(A1)<19,"",MID(A1,LEN(A1)-18,1))&IF(LEN(A1)<20,"",MID
(A1,LEN(A1)-19,1))&IF(LEN(A1)<21,"",MID(A1,LEN(A1)-20,1))&IF(LEN(A1)
<22,"",MID(A1,LEN(A1)-21,1))&IF(LEN(A1)<23,"",MID(A1,LEN(A1)-22,1))&IF
(LEN(A1)<24,"",MID(A1,LEN(A1)-23,1))&IF(LEN(A1)<25,"",MID(A1,LEN
(A1)-24,1))&IF(LEN(A1)<26,"",MID(A1,LEN(A1)-25,1))
So that:
abcdefghijklmnopqrstuvwxyz
in A1 becomes:
zyxwvutsrqponmlkjihgfedcba
But it's not very nice !!
