I am using poi 3.6
I am able to create the excel properly. But when I trying to set the cell type as number , it always give me cell type as general.
i.e. In the newly create excel , when I right click and go to format cell ->there I always found number to be a General.
My code is like this
style.setAlignment(CellStyle.ALIGN_RIGHT); dataCell.setCellValue(Float.parseFloat(value as String); dataCell.setCellType(Cell.CELL_TYPE_NUMERIC); dataCell.setCellStyle(style); Can you please suggest what is missing here ?

To create date cell which display current date to the cell, we can use Apache POI's style feature to format the cell according to the date. The setDateformat() method is used to set date format.
Select the cells. Select Home > Cell Style and select a style.
Apache POI uses the Workbook interface to represent an Excel file. It also uses Sheet, Row, and Cell interfaces to model different levels of elements in an Excel file. At the Cell level, we can use its getCellType() method to get the cell type.
The cell type specifies whether a cell can contain strings, numeric value, or formulas. A string cell cannot hold numeric values and a numeric cell cannot hold strings. The following code is used to create different types of cells in a spreadsheet.
You can try this approach too:
HSSFRow row = sheet.createRow(sheet.getLastRowNum()); HSSFCell cell = row.createCell(0); HSSFCellStyle style = workbook.createCellStyle(); style.setDataFormat(HSSFDataFormat.getBuiltinFormat("0.00")); cell.setCellStyle(style); cell.setCellValue(Float.parseFloat("21.5")); Of course, take a look at the documentation and examples about data formats.
