I don't understand your question. If you need to enter an array
within a formula, just type the characters normally. E.g.,
=SUM(LARGE(A1:A5,{1,2,3}))
If you are using an array formula, you don't type in the {}
characters. Instead, you press Ctrl+Shift+Enter rather than just
Enter, and Excel will automatically insert the {} character
around the formula. You don't type in the {} characters in an
array formula.
