You can try to set the cell type:

HSSFCell cell = row1.createCell(i);
cell.setCellType(Cell.CELL_TYPE_STRING); // =0, or Cell.CELL_TYPE_NUMERIC = 1
cell.setCellValue(value);

See the API docs for more information.

Below works for me.

**

HSSFCell cell = row1.createCell(i);
cell.setCellType(new Double(value));

**

Note: 'value' should be on numerals , it won't work on alphanumeric values. replace it wherever(cell values) it is required.
