Written by Ankur Goel

Here is a small code to write xlsx file though java code. 

You may need to include some of the jar files like

• xmlbeans-2.3.0.jar
• dom4j-1.1.jar
• poi-ooxml-schemas-3.6-20091214.jar
• poi-ooxml-3.6-20091214.jar
• poi-3.6-20091214.jar

You can google it and download and include it along with the below code.

import org.apache.poi.xssf.usermodel.XSSFWorkbook;

import org.apache.poi.ss.usermodel.*;

import java.io.*;

public class Start {

    public void WriteData()

    {

        try{

            Workbook[] wbs = new Workbook[] {  new XSSFWorkbook() };

            for(int i=0; i

            {

                Workbook wb = wbs[i];

                 Sheet s = wb.createSheet();

                Row r1=s.createRow(0);

                Cell c1=r1.createCell(0);

                c1.setCellValue("helo");

                c1=r1.createCell(1);

                c1.setCellValue((double)1);

                c1=r1.createCell(2);

                c1.setCellValue((double)3);

                c1=r1.createCell(3);

                c1.setCellFormula("B1+C1");

                String filename = "workbook.xlsx";

                FileOutputStream out = new FileOutputStream(filename);

                wb.write(out);

                out.close();

            }

        }catch(Exception e)

        {

            e.printStackTrace();

        }

    }

    public static void main(String[] args)

    {

        Start Object=new Start();

        Object.WriteData();

}

}

You can run the above code and a xlsx file is generated in the local directory. You will find some sample values you can then modify the code as required.
