Question

Answer 1

If you want complete certainty then you can use this code:

 for(Row blankRow : sheet)
    {
     for(int cn = 0; cn < blankRow.getLastCellNum(); cn++) 
        {
            Cell cells = blankRow.getCell(cn, Row.CREATE_NULL_AS_BLANK);
        }
    }

It marks all the null spaces as blank and then the CELL_TYPE_BLANK works like it should be working.
