How do I check if a cell contains a date value?

The code below check if the first cell of an Excel file contains a date value. In Excel the cell type for date is returned as HSSFCell.CELL_TYPE_NUMERIC, to make sure if it contains a date we can use a utility method HSSFDateUtil.isCellDateFormatted(HSSFCell cell), this method will check if the cell value is a valid date.

package org.kodejava.example.poi;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFDateUtil;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;


public class DateCellType {
    public static void main(String[] args) throws Exception {
        String filename = "datecelltype.xls";

        try (FileInputStream fis = new FileInputStream(filename)) {
            HSSFWorkbook workbook = new HSSFWorkbook(fis);
            HSSFSheet sheet = workbook.getSheetAt(0);

            // Read a cell the first cell on the sheet.
            HSSFCell cell = sheet.getRow(0).getCell(0);
            if (cell.getCellTypeEnum() == CellType.NUMERIC) {
                System.out.println("Cell type for date data type is numeric.");

            // Using HSSFDateUtil to check if a cell contains a date.
            if (HSSFDateUtil.isCellDateFormatted(cell)) {
                System.out.println("The cell contains a date value: " + cell.getDateCellValue());
        } catch (FileNotFoundException e) {

The example result of the code snippet:

Cell type for date data type is numeric.
The cell contains a date value: Wed Mar 01 17:36:59 WITA 2017

  1. I have both numeric cells and date cells in my spreadsheet. When I read then using POI, all of them are identified as Date type. How can I differentiate between numeric values and date values?
