Excel Return Array if condition is true

问题

I am trying to get something of the effect that when I have an if statement: if({TRUE;FALSE;TRUE},{1,2,3}) it will return with {1,3} is there any way to get this effect with an array of conditions and return an array of results?

回答1:

If one has the Dynamic Array Formula FILTER:

=FILTER({1,2,3},TRANSPOSE({TRUE;FALSE;TRUE}))

Without dynamic Array formula:

=TRANSPOSE(MODE.MULT(IF({TRUE;FALSE;TRUE},ROW(1:3)*{1,1})))

This is an array formula and depending on ones version, it may need to be confirmed with Ctrl-Shift-Enter when exiting edit mode.

回答2:

This formula will do what you say you want.

Note that there are a bunch of TRANSPOSE functions. This is because your Booleans are semicolon separated and your condition_if_true result is comma separated.

 =TRANSPOSE(AGGREGATE(15,6,IF(1/{TRUE;FALSE;TRUE},TRANSPOSE({1,2,3})),ROW(INDIRECT("1:"& SUM(--{TRUE,FALSE,TRUE})))))
