Determining the last row in a single column

Question

I have a sheet with data in cols A through H.

I need to determine the last row in column A that contains data (it\'s all conti

Answer 1

personally I had a similar issue and went with something like this:

function getLastRowinColumn (ws, column) {
  var page_lastrow = ws.getDataRange().getNumRows();
  var last_row_col = 0
  for (i=1; i<=page_lastrow;i++) {
    if (!(spread.getRange(column.concat("",i)).isBlank())) {last_row_col = i};
  }
  return last_row_col
}

It looks for the number of rows in the ws and loops through each cell in your column. When it finds a non-empty cell it updates the position of that cell in the last_row_col variable. It has the advantage of allowing you to have non-contiguous columns and still know the last row (assuming you are going through the whole column).
