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

I rewrote the getLastRow/getLastColumn functions to specify a row index or column index.

function get_used_rows(sheet, column_index){
      for (var r = sheet.getLastRow(); r--; r > 0) {
        if (sheet.getRange(1, 1, sheet.getLastRow(), sheet.getLastColumn()).getCell(r, column_index).getValue() != ""){
          return r;
          break;
        }
      }
    }

function get_used_cols(sheet, row_index){
  for (var c = sheet.getLastColumn(); c--; c > 0) {
    if (sheet.getRange(1, 1, sheet.getLastRow(), sheet.getLastColumn()).getCell(row_index, c).getValue() != ""){
      return c;
      break;
    }
  }
}
