I want to do something like this:
The value can be a character or some words.
If the value is number (for example = 0) then I can do:
sequence(11,6,0,0)
But I can't use a character or words.
Try this formula:
=ARRAYFORMULA(SUBSTITUTE(SEQUENCE(11,6,0,0), "0", "A"))
This uses SEQUENCE
but substitutes the "0" values for the required text value.
