I need to copy a XSSFSheet from one XSSFWorkbook to an other XSSFWorkbook. How can I do that? Can anyone help me please?

Thanks in advance

It’s a simple manipulation. You can do the vector to array and array to vector conversions easily, if required at any portion of the program.

excelData[1][0]=”Kushal”;
excelData[1][1]=”Paudyal”;
excelData[1][2]=”000-000-0000″;
excelData[1][3]=”IL,USA”;

excelData[2][0]=”Randy”;
excelData[2][1]=”Ram Robinson”;
excelData[2][2]=”111-111-1111″;
excelData[2][3]=”TX, USA”;

excelData[3][0]=”Phil”;
excelData[3][1]=”Collins”;
excelData[3][2]=”222-222-2222″;
excelData[3][3]=”NY, USA”;

return excelData;
}
how to make it more generic.I mean for an instance i have some 1000 records in my list after parsing ,so i cannot enter manually those 1000 records,how to make the cell grow dynamically???

public static String[][] preapreDataToWriteToExcel() {
try {
Parser ps = new Parser();
XMLReader xmlReader = null;
SAXParserFactory spfactory = SAXParserFactory.newInstance();
spfactory.setValidating(false);
SAXParser saxParser = spfactory.newSAXParser();
xmlReader = saxParser.getXMLReader();
xmlReader.setContentHandler(ps);
xmlReader.setErrorHandler(ps);
InputSource source = new InputSource(“C:/RunningShoes.xml”);

xmlReader.parse(source);
List sellersList = ps.getDetails();
for (ShoeCatalogBean seller : sellersList) {
System.out.println(sellersList.size());
String[][] excelData = new String[12][12];
excelData[0][0] = “CategoryGroup”;
excelData[0][1] = “Category”;
excelData[0][2] = “SubCategory”;
excelData[0][3] = “Gender”;
excelData[0][4] = “Brands”;
excelData[0][5] = “ProductName”;
excelData[0][6] = “StyleNumber”;
excelData[0][7] = “SelectedColor”;
excelData[0][8] = “Size”;
excelData[0][9] = “Width”;
excelData[0][10] = “Price”;
excelData[0][11] = “ProductDescription”;

excelData[1][0] = seller.getCategoryGroup();
excelData[1][1] = seller.getCategory();
excelData[1][2] = seller.getSubCategory();
excelData[1][3] = seller.getGender();
excelData[1][4] = seller.getBrands();
excelData[1][5] = seller.getProductName();
excelData[1][6] = seller.getStyleNumber();
excelData[1][7] = seller.getSelectedColor();
excelData[1][8] = seller.getSize();
excelData[1][9] = seller.getWidth();
excelData[1][10] = seller.getPrice();
excelData[1][11] = seller.getProductDescription();
……….
this is my piece of code.

Pls can you help me through this.

The method:
public static String [][] preapreDataToWriteToExcel(){
String [][] excelData = new String [4][4];
excelData[0][0]=”First Name”;
excelData [0][1]=”Last Name”;
excelData[0][2]=”Telephone”;
excelData[0][3]=”Address”;

excelData[1][0]=”Kushal”;
excelData[1][1]=”Paudyal”;
excelData[1][2]=”000-000-0000″;
excelData[1][3]=”IL,USA”;

excelData[2][0]=”Randy”;
excelData[2][1]=”Ram Robinson”;
excelData[2][2]=”111-111-1111″;
excelData[2][3]=”TX, USA”;

excelData[3][0]=”Phil”;
excelData[3][1]=”Collins”;
excelData[3][2]=”222-222-2222″;
excelData[3][3]=”NY, USA”;

return excelData;

}
Can we make String [][] excelData = new String [4][4]; more generic ,i mean to grow based on the length of the data present in the list. Because we are parsing a xml of some 3000 data and we cannot manually create the cell rows and columns.

For an instance in our apllication we are having something like this:
public class XmlToExcel {
public static void main(String[] args) {
String fileName = “C:\\temp\\testPOIWrite.xls”;
writeDataToExcelFile(fileName);
}

private static void writeDataToExcelFile(String fileName) {

String[][] excelData = preapreDataToWriteToExcel();

HSSFWorkbook myWorkBook = new HSSFWorkbook();
HSSFSheet mySheet = myWorkBook.createSheet();
HSSFRow myRow = null;
HSSFCell myCell = null;

for (int rowNum = 0; rowNum < 12; rowNum++) {
myRow = mySheet.createRow(rowNum);

for (int cellNum = 0; cellNum < 12; cellNum++) {
myCell = myRow.createCell(cellNum);
myCell.setCellValue(excelData[rowNum][cellNum]);

}
}

try {
FileOutputStream out = new FileOutputStream(fileName);
myWorkBook.write(out);
out.close();
} catch (Exception e) {
System.err.print(“In ” + e.getMessage());
}

}

/** Prepare some demo data as excel file content* */
public static String[][] preapreDataToWriteToExcel() {
try {
Parser ps = new Parser();
XMLReader xmlReader = null;
SAXParserFactory spfactory = SAXParserFactory.newInstance();
spfactory.setValidating(false);
SAXParser saxParser = spfactory.newSAXParser();
xmlReader = saxParser.getXMLReader();
xmlReader.setContentHandler(ps);
xmlReader.setErrorHandler(ps);
InputSource source = new InputSource(“C:/Women_RunningShoes.xml”);

xmlReader.parse(source);
List sellersList = ps.getDetails();
for (ShoeCatalogBean seller : sellersList) {
System.out.println(sellersList.size());
String[][] excelData = new String[12][12];
excelData[0][0] = “CategoryGroup”;
excelData[0][1] = “Category”;
excelData[0][2] = “SubCategory”;
excelData[0][3] = “Gender”;
excelData[0][4] = “Brands”;
excelData[0][5] = “ProductName”;
excelData[0][6] = “StyleNumber”;
excelData[0][7] = “SelectedColor”;
excelData[0][8] = “Size”;
excelData[0][9] = “Width”;
excelData[0][10] = “Price”;
excelData[0][11] = “ProductDescription”;

excelData[1][0] = seller.getCategoryGroup();
excelData[1][1] = seller.getCategory();
excelData[1][2] = seller.getSubCategory();
excelData[1][3] = seller.getGender();
excelData[1][4] = seller.getBrands();
excelData[1][5] = seller.getProductName();
excelData[1][6] = seller.getStyleNumber();
excelData[1][7] = seller.getSelectedColor();
excelData[1][8] = seller.getSize();
excelData[1][9] = seller.getWidth();
excelData[1][10] = seller.getPrice();
excelData[1][11] = seller.getProductDescription();

excelData[2][0] = seller.getCategoryGroup();
excelData[2][1] = seller.getCategory();
excelData[2][2] = seller.getSubCategory();
excelData[2][3] = seller.getGender();
excelData[2][4] = seller.getBrands();
excelData[2][5] = seller.getProductName();
excelData[2][6] = seller.getStyleNumber();
excelData[2][7] = seller.getSelectedColor();
excelData[2][8] = seller.getSize();
excelData[2][9] = seller.getWidth();
excelData[2][10] = seller.getPrice();
excelData[2][11] = seller.getProductDescription();
………
return excelData;
}

} catch (Exception e) {
System.err.println(e);
System.exit(1);
}
return null;
}

}

Any help would be appreciated.
I feel i posted a too big comment:-)

Use the following tutorial to learn how to read XML Files in Java which I wrote Just today.

http://sanjaal.com/java/2009/07/21/read-xml-file-in-java-using-dom-a-simple-tutorial/

See the notes at the end of the above tutorial on how you can writes contents thus read from XML to the excel files. Hope my suggestions will guide you to write directions.

Since both are working codes, you should have no problems modifying them to suit your needs.

} catch (FileNotFoundException e) {

e.printStackTrace();

}

}
It will be of great help if you can guide me through this.

But is there any way to read word comments and bookmarks using Java? Do u have a sample code? Any help would be appreciated.

Thanking you,
Bihag Raval

the coding works perfectly

i was searching POI Coding for past 2 days but atlast i got ur site and worked fine
Thanks
