Answer 1

Error: NullPointerException on org.apache.poi.ss.util.SheetUtil.getCellWidth(SheetUtil.java:122)

Fix: Always set value to Cell as shown below, it throws NullPointerException when there is null in Cell, so set the value as:

Cell c = row.createCell(i);
c.setCellValue(text == null ? "" : text );
