RussianNo, the exception is not because of using trial version or old version of Aspose(although the recommended version to be used is always the latest one, you should use Aspose.Cells for Java 7.4.2 and Aspose.Slides for Java 7.2.0)
For handling xlsx and pptx files, you will have to modify your conversion methods as follows:
public void convertPPTToPDF(String Path) throws Exception
{
String extension = "";
Integer index = Path.lastIndexOf(".");
if (index > 0) {
extension = Path.substring(index+1);
}
if (extension.equals("ppt"))
{
Presentation pres = new Presentation(Path);
String destPath=Path.substring(0, index)+".pdf";
pres.saveToPdf(destPath);
}
else if (extension.equals("pptx"))
{
//Instantiate a PresentationEx object that represents a PPTX file
PresentationEx pres = new PresentationEx(Path);
String destPath=Path.substring(0, index)+".pdf";
//Saving the PPTX presentation to PDF document
pres.save(destPath, com.aspose.slides.SaveFormat.Pdf);
}
System.out.println("Powerpoint file converted to PDF successfully");
}
public void convertExcelToPDF(String Path) throws Exception
{
String extension = "";
Integer index = Path.lastIndexOf(".");
if (index > 0) {
extension = Path.substring(index+1);
}
if (extension.equals("xls"))
{
Workbook workbook = new Workbook(Path);
//Save the document in PDF format
String destPath=Path.substring(0, index)+".pdf";
workbook.save(destPath, FileFormatType.PDF);
}
else if (extension.equals("xlsx"))
{
//Createing and XLSX LoadOptions object
LoadOptions loadOptions = new LoadOptions(FileFormatType.XLSX);
//Creating an Workbook object with 2007 xlsx file path and the loadOptions object
Workbook workbook = new Workbook(Path, loadOptions);
String destPath=Path.substring(0, index)+".pdf";
workbook.save(destPath, FileFormatType.PDF);
}
System.out.println("Excel file converted to PDF successfully");
}
I have checked that the updated methods are working fine for ppt, pptx, xls and xlsx files with latest version of Aspose.Cells and Aspose.Slides for Java.
I am a developer evangelist at Aspose.
