Suppose I have a formula written as text, such as "=15+4", is there any way to convert this text back into a formula so that I will see the answer "19"?

Simply put, I am looking for a function which does the same as =FORMULATEXT(), but in reverse.

I Googled it and some respondent had written on another forum that it can't be done. I saw someone else had been able to use a Power Query called "Evaluate", but as I am running Excel on a Mac that kind of Power Query does not seem to be available to me.
