    Apologies - clearly I missed that - try the following instead:

    =CHAR(65+INT((ROW(A1)-1)/26)) & CHAR(65+MOD(ROW(A1)-1,26))

    Try entering

    =CHAR(65+INT((ROW(A1)-1)/26)) & CHAR(65+MOD(ROW(A1)-1,26))

    in the first cell and then drag it down...

    Just for the sake of showing an alternative that works in modern Excel.

    =TOCOL(CHAR(SEQUENCE(3,,65))&TRANSPOSE(CHAR(SEQUENCE(26,,65))))

    This will spill a dynamic array (1 column, 78 rows) starting with "AA" and finishing with "CZ".
