[java] Getting Exception(org.apache.poi.openxml4j.exception - no content type [M1.13]) when reading xlsx file using Apache POI?

i'm using Apache POI(XSSF API) for reading xlsx file.when i tried to read file.i got the following error:

org.apache.poi.POIXMLException: org.apache.poi.openxml4j.exceptions.InvalidFormatException: Package should contain a content type part [M1.13]

please help me to sort out this problem.

Try saving the file as Excel Workbook ONLY. NOT any other format. It worked for me. I was getting the same error.

You get this exact error should you pass an old school .xls file into this API. Save the .xls as a .xlsx and then it will work.

Cleaned up the code (commented out the logger mostly) to make it run in my Eclipse environment.

Created this little testcode:

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;


public class ReadXLSXTest {

/**
 * @param args
 * @throws FileNotFoundException 
 */
public static void main(String[] args) throws FileNotFoundException {
    // TODO Auto-generated method stub


    ReadXLSX test = new ReadXLSX(new FileInputStream(new File("./sample.xlsx")));

    System.out.println(test.getSheetsName());
    System.out.println(test.getNumberOfSheet());


}

}

All this ran like a charm, so my guess is you have an XLSX file that is 'corrupt' in one way or another. Try testing with other data.

If the excel file is password protected, then this error comes up.

I get the same exception for .xls file, but after I open the file and save it as xlsx file , the below code works:

 try(InputStream is =file.getInputStream()){
      XSSFWorkbook workbook = new XSSFWorkbook(is);
      ...
 }

You might also see this error if you attempt to parse the same file twice from the same source.

I was parsing the file once to validate and again (from the same InputStream) to process - this produced the above error.

To get round this I parsed the source file into 2 different InputStreams, one to validate and one to process.

I was using XSSFWorkbook to read .xls, which resulted in InvalidFormatException. I have to use a more generic Workbook and Sheet to make it work.

This post helped me solved my problem.

Pretty sure that this exception is thrown when the Excel file is either password protected or the file itself is corrupted. If you just want to read a .xlsx file, try my code below. It's a lot more shorter and easier to read.

import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.Sheet;
//.....

static final String excelLoc = "C:/Documents and Settings/Users/Desktop/testing.xlsx";

public static void ReadExcel() {
InputStream inputStream = null;
   try {
        inputStream = new FileInputStream(new File(excelLoc));
        Workbook wb = WorkbookFactory.create(inputStream);
        int numberOfSheet = wb.getNumberOfSheets();

        for (int i = 0; i < numberOfSheet; i++) {
             Sheet sheet = wb.getSheetAt(i);
             //.... Customize your code here
             // To get sheet name, try -> sheet.getSheetName()
        }
   } catch {}
}
