"The package must contain part of the content type [M1.13]"

Question

I try to write to an Excel file, but I get an error:

An exception in the stream "main" org.apache.poi.POIXMLException: org.apache.poi.openxml4j.exceptions.InvalidFormatException: The package must contain part of the content type [M1.13]

From what I understand, I miss a flask.

Can someone help me determine which file is this?

PS I am using Netbeans.

        wb = new XSSFWorkbook(fis);  
        s = wb.getSheetAt(0);

    }      

}

Answer 1

Use file extension to process WorkSheettype

  String inputFilename = new File(path).getName();

                    switch (inputFilename.substring(inputFilename.lastIndexOf(".") + 1,
                            inputFilename.length())) {
                        case "xls":
                            return readXLS(path);

                        case "xlsx":
                            return readXLSX(path);
                        default:
                            Log.e(TAG, "No XLS file chosen");
                            return "Please select valid \"Excel\" File\"";
                    }

For xlsx file: use XSSFWorkbook & XSSFSheet

    XSSFWorkbook workbook = new XSSFWorkbook(new FileInputStream(new File(path)));

    XSSFSheet sheet = workbook.getSheetAt(0);

For xls file: use HSSFWorkbook & HSSFSheet

    HSSFWorkbook workbook = new HSSFWorkbook(new FileInputStream(new File(path)));

    HSSFSheet sheet = workbook.getSheetAt(0);

Answer 9

, , , line3 :

File xlsxFile = new File( "C:\\myWorkbook.xlsx" );
FileInputStream finXLSX = new FileInputStream( xlsxFile ); //line1

FileOutputStream foutXLSX = new FileOutputStream( xlsxFile ); //line2

XSSFWorkbook workSheet = new XSSFWorkbook( finXLSX ); //line3

But I realized that line3 does not work, since I also opened the output stream for my xlsx file via line2, and then the execution of line3 was unsuccessful. I removed line2 to make it work.
