Question

How can I find the last row that contains data in a specific column and on a specific sheet?

Answer 1

function LastRowIndex(byval w as worksheet, byval col as variant) as long
  dim r as range

  set r = application.intersect(w.usedrange, w.columns(col))
  if not r is nothing then
    set r = r.cells(r.cells.count)

    if isempty(r.value) then
      LastRowIndex = r.end(xlup).row
    else
      LastRowIndex = r.row
    end if
  end if
end function

Usage:

? LastRowIndex(ActiveSheet, 5)
? LastRowIndex(ActiveSheet, "AI")
