Class DateFormatConverter

java.lang.Object
  org.apache.poi.ss.util.DateFormatConverter

public class DateFormatConverter
extends java.lang.Object

Convert java DateFormat patterns into Excel custom number formats. For example, to format a date in excel using the "dd MMMM, yyyy" pattern and Japanese locale, use the following code:

      // returns "[$-0411]dd MMMM, yyyy;@" where the [$-0411] prefix tells Excel to use the Japanese locale
      String excelFormatPattern = DateFormatConverter.convert(Locale.JAPANESE, "dd MMMM, yyyy");

      CellStyle cellStyle = workbook.createCellStyle();

      DataFormat poiFormat = workbook.createDataFormat();
      cellStyle.setDataFormat(poiFormat.getFormat(excelFormatPattern));
      cell.setCellValue(new Date());
      cell.setCellStyle(cellStyle);  // formats date as '2012?3?17?'
