org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException in POI API after an .xls file is updated with Libre Office

Question

I am reading an Excel using POI api, I use the following code to read the excel file.

    public class ExcelWorkBook {

        private static ExcelWorkBook excelWorkBook = null;
        private static String filePath;
        private static XSSFWorkbook workbook;

        /**
         * This  constructor used to initialize the {@link ExcelWorkBook}
         * @throws IOException
         */
        private ExcelWorkBook() throws IOException {
            try {
                workbook = new XSSFWorkbook(getFile());
            } catch (FileNotFoundException ex) {
                Logger.getLogger(ExcelWorkBook.class.getName()).log(Level.SEVERE, null, ex);
            }
        }

        /**
         * This method create a new object {@link ExcelWorkBook}
         * @return {@link ExcelWorkBook}
         * @throws IOException
         */
        public static ExcelWorkBook getInstance() throws IOException {
            excelWorkBook = new ExcelWorkBook();
            return excelWorkBook;
        }

        /**
         * This method create a {@link FileInputStream}
         * @return {@link FileInputStream}
         * @throws FileNotFoundException
         */
        private FileInputStream getFile() throws FileNotFoundException {
          FileInputStream file = new FileInputStream(new File(filePath));
          return file;
        }
        .
        .
        .
        .

But its throwing following exception in a particular file which is created using MS Office 2010 and undated using Libre office. What could Be the problem. The Stack trace of exception is attached below

Answer 1

I had exactly the same exception after I edited with Libe Office a .xlsx file containing comments. The removal of the comments solved the issue.

Answer 2

Your Excel will be parsed into XML first. This exception happens when the xml is invalid. This can be the case when you create the Excel Sheet with Microsoft Office and then edit the Sheet with some other Software like Libre or Open office.

I don't know what it is that Open Office or Libre Office do, but they do something to the document that POI doesn't like.

Use Microsoft Excel to read or edit your sheets. It worked for me, unfortunately.

Answer 3

I have inserted org.apache.xmlbeans in project. It helped.
