title: Can I reference a range, within a function, that goes down to infinity?
body: <p>E.g. I put in cell O3 [=SUM(O4:O15901)]</p>
  
  <p>Let's say I may copy this formula elsewhere, or add more cells in column O in the future. Is there any way to just tell it to go all the way down, e.g. [=SUM(O4:O*)] or something?</p>
