How can I return the value of an empty cell using a formula?

Question

Google Sheets

It is necessary that, according to the condition, the cell has either a value or is empty (but not "").

Answer 1

I like the reference to an empty range the best. Just create a named range, in my case it is BLANK, which refers to some always empty cell. Further, for example, in B1
=IF(A1=1;BLANK;A1)
If to C1add =ISBLANK(B1), then it will returnTRUE
