Hi Support,

I am facing an issue while converting PDF to Excel file suing ASPOSE API. My scenario is to create a single sheet Excel file for all the pages exist in the PDF. I am creating xls and xlsx file. While opening xls file it shows error (for reference please check XLSFileError.png file). When we open the file through option “Do you want to open it anyway”, it shows all the content in single sheet. But when we close this file it always ask “Want to save your changes”. Somehow Aspose API is creating corrupted Excel files. Also we are not able to open XLSX file created from ASPOSE API. We are getting error which you can check in file “XLSXFileError.png”.

I am attaching two PDF file with converted XLS and XLSX files. Also I am attaching java code and error png files for references. Please check and let me know how we can sole this.

Thanks

Vishal

Hi Vishal,

Thanks for contacting support.

This warning message of MS Excel version 2007 and higher is not a bug. This message appears because Aspose.Pdf provides saving in MS Excel 2003 XML format. Whereas when using .xls file extension for output file, it is correct for lower versions of MS Excel. the Versions of MS Excel 2007 and higher expect .xls file extension for binary document of lower versions Excel, and *.xml for XML.

If you save an Excel document as xml with .xls extension in MS Excel 2003, and then try open it in MS Excel version 2007 or higher version, it will result in same warning message. So, its not a bug of Aspose.Pdf for Java. Therefore in order to avoid this warning message, you can change output file extension. Code snippet:

[Java]

Document doc = new Document("C:\\pdftest\\FA16_Size_Matrix_Artwork 1.5.16.pdf");

com.aspose.pdf.ExcelSaveOptions excelSaveOptions = new com.aspose.pdf.ExcelSaveOptions();

doc.save("C:\\pdftest\\FA16_Size_Matrix_Artwork 1.5.16.xml", excelSaveOptions);

See attached files and you can open them using in MS Excel version 2007 and higher without any warning messages.

Thanks for reply. Now if I am saving file as xlsx extension then it is creating file without any error but I am not able to open this file. Can you please check this and let me know why this is coming? I have also attached sample xlsx file.

Please provide an update on this as this is blocking our development.

Hi Vishal,


Thanks for sharing the details.

As shared earlier, please use xml as extension instead of xlsx and resultant file can be viewed using MS Excel.

Hi Vishal,

Thanks for your patience.

We have further investigated earlier reported issue and it does not seem to be a bug. We produce raw XML file. But formats such as Office 2003 XML are not supported by POI. Howecer you can use Aspose.Cells-16.11 to convert raw XML file into XLSX format.

[Java]

com.aspose.cells.Workbook workbook = 
    new com.aspose.cells.Workbook(myDir + "FA16_Size_Matrix_Artwork 1.5.16_new.xml");

workbook.save(myDir + "out1.xlsx", com.aspose.cells.SaveFormat.XLSX);

// Using Apache POI to open the generated XLSX file
OPCPackage pkg = OPCPackage.open(new File(myDir + "out1.xlsx"));
XSSFWorkbook wb1 = new XSSFWorkbook(pkg);

// Alternative approach using InputStream
InputStream inp = new FileInputStream(myDir + "out1.xlsx");
org.apache.poi.xssf.usermodel.XSSFWorkbook wb2 = new org.apache.poi.xssf.usermodel.XSSFWorkbook(inp);
