How to determine empty row?

Question

How I can determine empty rows in .xls documents using Apache POI?

Answer 1

If you are using apache-poi [4+]:

Then the below method works for you. As the other methods suggested did not work for me, I had to do it this way.

public static boolean isRowEmpty(Row row) {
    boolean isEmpty = true;
    DataFormatter dataFormatter = new DataFormatter();
    if(row != null) {
        for(Cell cell: row) {
            if(dataFormatter.formatCellValue(cell).trim().length() > 0) {
                isEmpty = false;
                break;
            }
        }
    }
    return isEmpty;
}

The method dataFormatter.formatCellValue(cell) would return "", an empty / ZERO length string when the cell is either null or BLANK.

The import statements for your reference:

import org.apache.poi.ss.usermodel.DataFormatter;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Cell;

Hope this helps!
