WHILE loop with a live formula

Perhaps you meant to reply to this thread?

Because both that thread and your solution require a button click. The one in this thread was an attempt to find a way to while-loop without a button but with a column formula.

Nice effort btw. Your approach avoids doc recalculations. But if one has to use RunActions()within a loop, then recalculations (and thus delays between iterations) are unavoidable and your method isn’t any faster than mine.
