I sincerely believe that spreadsheets are one of the most useful tools for teachers. I have said it more than once and, for me, should be one of the digital skills of a teacher. It’s true that I haven’t dedicated much time to them in this blog. A couple of years ago I dedicated one to the IMPORTRANGE formula. Today I will talk about another formula that can also be very useful, ARRAYFORMULA. It is especially useful when working with spreadsheets that collect responses from Google forms.
