Created attachment 33399 [details] Test file for reproducing the error message. The attached file was generated by POI to allow user to edit the metadata and import back into the application. However, after I edited the file with LibreOffice Calc on Linux, it gives me an exception trying to load a user uploaded file into XSSFWorkbook. Steps to Reproduce: 1. Open the attached file into a InputStream 2. Create a workbook from the InputStream InputStream inp2 = new FileInputStream("/home/lei/Downloads/Test combine new.xlsx"); XSSFWorkbook xlsxWb2 = (XSSFWorkbook) WorkbookFactory.create(inp2); Actual Results - the application threw the following Error Messages: org.apache.poi.POIXMLException: java.lang.reflect.InvocationTargetException at

I forgot to mention that when I edited and saved the same file with Microsoft Excel or Google Spreadsheet, this error did not occur.
This is a known bug of windows excel. The generated xml can contain multiple instances of the same attribute in a single tag. The only workaround I found is to modify the org.apache.xmlbeans.impl.piccolo.xml.AttributeHolder class in order to ignore duplicate attributes. Example: public void addAndCheckAttribute(String uri, String localName, String qName, String type, String value) throws SAXException { for (int i = 0; i < this.length; ++i) { if (this.data[(i * 5 + 2)] == qName) { //throw new FatalParsingException("duplicate attribute '" + qName + "'"); setAttribute(i, uri, localName, qName, type, value); } } addAttribute(uri, localName, qName, type, value); }
It works fine when I modified and saved the file with Microsoft Excel or Google Spreadsheet. But it does not work when I modified and saved it with LibreOffice Calc 4.2.8.2 on CentOS 6.
As far as I read the discussion this is not caused by POI itself, but rather by LibreOffice, right? Therefore I am closing this for now, if this is really a problem in POI, then please reopen with a unit-test that can be used to reproduce this.
