Add Custom XML Part using Apache POI - java

What is the proper way to add custom XML Part to XLSX file using Apache POI?
I have tried creating package part and add relation to workbook using the code below, but my newly added part is added as blank file because the workbook clears package parts in POIXMLDocument#prepareForCommit().
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import org.apache.poi.POIXMLDocumentPart;
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.openxml4j.opc.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class AddCustomXmlPart {
public static void main(String[] args) {
String outputFileName = System.getProperty("user.home") + "/Documents/test-updated.xlsx";
try {
XSSFWorkbook workbook = new XSSFWorkbook();
workbook.createSheet("Test");
addCustomXmlPart(workbook);
workbook.write(new FileOutputStream(outputFileName));
} catch (IOException e) {
e.printStackTrace();
} catch (InvalidFormatException e) {
e.printStackTrace();
}
}
private static void addCustomXmlPart(XSSFWorkbook workbook) throws IOException, InvalidFormatException {
final OPCPackage opcPackage = workbook.getPackage();
final PackagePartName partName = PackagingURIHelper.createPartName("/customXml/item1.xml");
final PackagePart part = opcPackage.createPart(partName, ContentTypes.PLAIN_OLD_XML);
final OutputStream outputStream = part.getOutputStream();
outputStream.write("<test>A</test>".getBytes());
outputStream.close();
final PackageRelationship packageRelationship = part.addRelationship(
partName, TargetMode.INTERNAL, PackageRelationshipTypes.CUSTOM_XML);
final POIXMLDocumentPart documentPart = new POIXMLDocumentPart(workbook, part, packageRelationship);
workbook.addRelation(packageRelationship.getId(), documentPart);
}
}

As suggested by Gagravarr:
import java.io.*;
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.openxml4j.opc.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class AddCustomXmlUsingOpc {
public static final String PARENT_PATH = System.getProperty("user.home") + "/Documents/";
public static void main(String[] args) {
String outputFileName1 = PARENT_PATH + "01.xlsx";
String outputFileName2 = PARENT_PATH + "02.xlsx";
try {
XSSFWorkbook workbook = new XSSFWorkbook();
workbook.createSheet("Test");
workbook.write(new FileOutputStream(outputFileName1));
final OPCPackage opcPackage = OPCPackage.open(new File(outputFileName1));
addCustomXmlPart(opcPackage);
opcPackage.save(new File(outputFileName2));
} catch (IOException e) {
e.printStackTrace();
} catch (InvalidFormatException e) {
e.printStackTrace();
}
}
private static void addCustomXmlPart(OPCPackage opcPackage) throws IOException, InvalidFormatException {
final PackagePartName partName = PackagingURIHelper.createPartName("/customXml/item1.xml");
final PackagePart part = opcPackage.createPart(partName, ContentTypes.PLAIN_OLD_XML);
final OutputStream outputStream = part.getOutputStream();
outputStream.write("<test>A</test>".getBytes());
outputStream.close();
part.addRelationship(partName, TargetMode.INTERNAL, PackageRelationshipTypes.CUSTOM_XML);
final PackagePartName workbookName = PackagingURIHelper.createPartName("/xl/workbook.xml");
final PackagePart workbookPart = opcPackage.getPart(workbookName);
workbookPart.addRelationship(partName, TargetMode.INTERNAL, PackageRelationshipTypes.CUSTOM_XML);
}

Apache poi : setting custom properties at worksheet level using apache poi

public static void main(String[] args) {
try {
FileInputStream file = new FileInputStream(new File("D://New Microsoft Excel Worksheet.xlsx"));
XSSFWorkbook wb = new XSSFWorkbook(file);
XSSFSheet sheet = wb.createSheet("newsheet5");

props.addNewCustomPr().setId("APACHE POI");

Xlsx file is corrupted after writing custom properties at sheet level.
I'm getting an error message as 'excel cannot open the file because the file format or file extension is not valid . Vefiry that the file has not been corrupted and the file extension matches the format of the file' when tried open the excel file.
Sheet custom properties only are useable using VBA. They are stored in the Excel file but the values are within binary document parts customProperty1.bin, customProperty2.bin, ... This is nothing what apache poi provides access to until now.
Using XSSF one needs creating the binary document part, then getting the relation Id to that binary document part. Then set CTCustomProperties - CTCustomProperty. There the Id points to the binary document part containing the value and the name is the property name.
Following complete example shows this. It is tested and works using current apache poi 4.1.2. It needs ooxml-schemas-1.4.jar being in class path because default poi-ooxml-schemas-4.1.2.jar does not contain all needed low level CT*-classes.

I've been struggling with the same issue and found a way to make it work, but it's far from optimal. Here it is anyway and hopefully you or someone else can come up with a better method.
package temp.temp;
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.List;
import org.apache.poi.ooxml.POIXMLDocumentPart;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.openxmlformats.schemas.spreadsheetml.x2006.main.CTCustomProperties;
import org.openxmlformats.schemas.spreadsheetml.x2006.main.CTCustomProperty;
import org.openxmlformats.schemas.spreadsheetml.x2006.main.CTWorksheet;
public class Temp2 {
public static void main(String[] args) {
File inputFile = new File("C:\\myspreadsheet.xlsx");
try (BufferedInputStream fis = new BufferedInputStream(new FileInputStream(inputFile))) {
XSSFWorkbook wb = new XSSFWorkbook(fis);
for (int i = 0; i < wb.getNumberOfSheets(); i++) {
XSSFSheet sheet = wb.getSheetAt(i);
System.out.println("\nSheetName=" + sheet.getSheetName());
CTWorksheet ctSheet = sheet.getCTWorksheet();
CTCustomProperties props = ctSheet.getCustomProperties();
if (props != null) {
List<CTCustomProperty> propList = props.getCustomPrList();
propList.stream().forEach((prop) -> {
POIXMLDocumentPart rel = sheet.getRelationById(prop.getId());
if (rel != null) {
try (InputStream inp = rel.getPackagePart().getInputStream()) {
byte[] inBytes = inp.readAllBytes();
// By experimentation, byte array has two bytes per character with least
// significant in first byte which is UTF-16LE encoding. Don't know why!
String value = new String(inBytes, "UTF-16LE");
System.out.println(" " + prop.getName() + "=" + value);
} catch (IOException ioe) {
//Error
}
}
});
}
}
wb.close();
} catch (Exception e) {
System.out.println(e);
}
System.out.println("End");
}
}
Note that CTWorksheet comes from poi-ooxml-schemas-xx.jar and CustomProperties from ooxml-schemas-yy.jar, so both have to be on the classpath. If you're using modules (as I am), this gives big problems! Good Luck

Unable to write to Excel using Selenium webdriver

I have created a test where I am reading from excel and iterating through a worksheet to process an application in a web portal. This is working as expected.
However I am now trying to write results from the web page into another sheet on the same excel. The test case I am running passes in Eclipse but no data is written to the specified sheet. (I'm also looking to iterate on the results sheet to capture multiple application records, haven't got to that part yet).
Please see below my test script and the methods I have created in an ExcelConfig util sheet. Hoping someone can advise where I'm going wrong, thanks in advance.
