this code has been adapted from what I found here on coderanch forum
public final class ExcelDocumentConverter { public static XSSFWorkbook convertWorkbookHSSFToXSSF(HSSFWorkbook source) { XSSFWorkbook retVal = new XSSFWorkbook(); for (int i = 0; i styleMap = (copyStyle) ? new HashMap() : null; for (int i = source.getFirstRowNum(); i maxColumnNum) { maxColumnNum = srcRow.getLastCellNum(); } } } for (int i = 0; i styleMap) { // manage a list of merged zone in order to not insert two times a // merged zone Set mergedRegions = new TreeSet(); destRow.setHeight(srcRow.getHeight()); // pour chaque row for (int j = srcRow.getFirstCellNum(); j styleMap) { if (styleMap != null) { int stHashCode = oldCell.getCellStyle().hashCode(); HSSFCellStyle sourceCellStyle = styleMap.get(stHashCode); XSSFCellStyle destnCellStyle = newCell.getCellStyle(); if (sourceCellStyle == null) { sourceCellStyle = oldCell.getSheet().getWorkbook().createCellStyle(); } destnCellStyle.cloneStyleFrom(oldCell.getCellStyle()); styleMap.put(stHashCode, sourceCellStyle); newCell.setCellStyle(destnCellStyle); } switch (oldCell.getCellType()) { case HSSFCell.CELL_TYPE_STRING: newCell.setCellValue(oldCell.getStringCellValue()); break; case HSSFCell.CELL_TYPE_NUMERIC: newCell.setCellValue(oldCell.getNumericCellValue()); break; case HSSFCell.CELL_TYPE_BLANK: newCell.setCellType(HSSFCell.CELL_TYPE_BLANK); break; case HSSFCell.CELL_TYPE_BOOLEAN: newCell.setCellValue(oldCell.getBooleanCellValue()); break; case HSSFCell.CELL_TYPE_ERROR: newCell.setCellErrorValue(oldCell.getErrorCellValue()); break; case HSSFCell.CELL_TYPE_FORMULA: newCell.setCellFormula(oldCell.getCellFormula()); break; default: break; } } /** * Récupère les informations de fusion des cellules dans la sheet source * pour les appliquer à la sheet destination...

Since all of the above answers don't help, here is working code:
Just write a main method that fills the necessary fields and uses transform().

See the article Upgrading to POI 3.5, including converting existing HSSF Usermodel code to SS Usermodel (for XSSF and HSSF). There's an example here.
回答5:
Seems to me like you should use the 'SS Usermodel'. See Apache POI's website for more on the subject.
