我正在尝试使用aspose单元格从excel文件中提取ole对象。在所需位置成功提取excel文件时，提取的文件不会在excel中打开。我在打开时收到这个消息：打开提取的excel文件时收到的消息
我也试过aspose-cells-20.3和20.8，但问题是一样的。
提取excel文件的代码是：

private static void extractEmbeddedImages(Workbook workbook) throws Exception {
        // Get the OleObject Collection in the first worksheet.
        OleObjectCollection oles = workbook.getWorksheets().get(0).getOleObjects();
        PrintWriter ws=new PrintWriter(new File(sDataDir + "/" + sFileNameWithoutExt + "_EmbeddedFiles.txt"));
        //PrintWriter ws=new PrintWriter(new File(sDataDir + "/EmbeddedFiles.txt"));

        // Loop through all the ole objects and extract each object. in the worksheet.
        for (int i = 0; i < oles.getCount(); i++) {
            if(oles.get(i).getUpperLeftColumn() < excludeColFrom) {
                if (oles.get(i).getMsoDrawingType() == MsoDrawingType.OLE_OBJECT) {
                    OleObject ole = (OleObject) oles.get(i);

                    String sRow=""+ole.getActualLowerRightRow();

                    com.aspose.cells.Cell cell  =  workbook.getWorksheets().get(0).getCells().getCell(Integer.parseInt(sRow), ole.getLowerRightColumn());
                    String sOrgFile=ole.getSourceFullName();

                    if(sOrgFile == null) //This code is only skipping those file with null resourceFullNme. 
                    {

                        if(ole.getProgID().equalsIgnoreCase("Bitmap Image"))
                            sOrgFile = ole.getLowerRightColumn()+ ".jpg";

                    }
                    else if(ole.getProgID().equalsIgnoreCase("Acrobat Document"))
                        sOrgFile = sOrgFile+".pdf";

                    String sFnamme= new File(sOrgFile).getName();

                    sFnamme = sFnamme.substring(sFnamme.lastIndexOf("\\")+1);

                    boolean isExits=isAlreadyExits((Integer.valueOf(sRow)-1)+"_"+sFnamme);
                    if(isExits)
                        sFnamme=(Integer.valueOf(sRow)-4)+"_Temp_"+sFnamme;
                    else
                        sFnamme=(Integer.valueOf(sRow)-4)+"_"+sFnamme;

                    FileOutputStream fos;
                    try {
                        byte[] data = ole.getObjectData();
                        if(data != null) {
                            fos = new FileOutputStream(sDownloadDir + "/" +sFnamme);

                            try {
                                fos.write(data);
                            } catch (IOException e1) {
                                // TODO Auto-generated catch block
                                e1.printStackTrace();
                            }
                            try {
                                fos.close();
                                ws.println(sFnamme);

                            } catch (IOException e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();
                            }
                        }
                    } catch (FileNotFoundException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
            }
        }
        ws.close();
    }

请帮忙。
提前谢谢
