Hello Developers,

I am using Jdeveloper 12.2.1. My requirement is to export data into excel that is working perfectly. but when I open excel so all the data comes into General(String) format and I want

Number into Number format and Date into Date format.

I used below code to change format for Date but its still coming in general(String) Format.

(("Birthdate".equalsIgnoreCase(colName))) {

                            CellStyle cellStyle = workbook.createCellStyle();

                            CreationHelper createHelper = workbook.getCreationHelper();

                            cellStyle.setDataFormat(

                                createHelper.createDataFormat().getFormat("dd-MMM-yy"));

                            cell.setCellValue(CellValue);

                            cell.setCellStyle(cellStyle);

Please help.
