package knvbj;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.List;
import org.apache.poi.ss.usermodel.Row;

import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.nodes.TextNode;
import org.jsoup.select.Elements;

public class KNVBJ {

private static int Clnummer=1;
    public static void main(String[] args) throws IOException {       
        List urlList = ReadXlsx.readXlsx();
        urlList.get(1);
        for (String url : urlList) {
        System.out.println("url: " + url);
    }

    for (int i = 0; i < urlList.size(); i++) {
        Document doc = Jsoup.connect(urlList.get(i))
                .data("query", "Java")
                .userAgent("Mozilla")
                .cookie("auth", "token")
                .timeout(3000)
                .post();

        Element content1 = doc.getElementsByClass("details").first();
        String body = content1.toString();
        Document docb = Jsoup.parseBodyFragment(body);
        Element bbd = docb.body();
        String kkj = bbd.toString();                

        Document finalDocument = Jsoup.parse(kkj);
        Element ClubName = finalDocument.getElementsByClass("title").first();
        String NameOfClub = ClubName.text();
        System.out.println(NameOfClub);    

        Element Adres = finalDocument.getElementsByClass("text").get(1);

        String[] addressParts = Adres.html().split("

        String SplitString;
        String PlaatsName;
        String Straat;
        String telNo;
        String Accommodatie;
        String Postcode;                

        Accommodatie = addressParts[0].trim();
        Straat = addressParts[1].trim();
        SplitString = addressParts[2].trim();
        telNo = addressParts[3].trim();

        String splitted[]= SplitString.split(" ");
        Postcode = splitted[0];
        PlaatsName = splitted[1];

        System.out.println(Accommodatie + " " + Straat + " " + " postcode " + Postcode + " Plaatsname " + PlaatsName+ " "+ telNo);

        Elements anchors = finalDocument.getElementsByTag("a");
        String email = anchors.get(1).text();    

        String fname = "/Users/muratcanpinar/Downloads/KNVBJ/src/knvbj/Voetbalclubs.xlsx";
        InputStream inp = new FileInputStream(fname);                       

        Workbook wb = new XSSFWorkbook(inp);

        Sheet sheet = wb.getSheetAt(0);
        Row r1 = sheet.getRow(0);

        r1.createCell(Clnummer++).setCellValue(NameOfClub);
        r1.createCell(Clnummer++).setCellValue(Accommodatie);
        r1.createCell(Clnummer++).setCellValue(Straat);
        r1.createCell(Clnummer++).setCellValue(Postcode);
        r1.createCell(Clnummer++).setCellValue(PlaatsName);
        r1.createCell(Clnummer++).setCellValue(telNo);
        r1.createCell(Clnummer++).setCellValue(email);                          
    }
FileOutputStream out = new FileOutputStream("/Users/muratcanpinar/Downloads/KNVBJ/build/classes/knvbj/ClubI nformation.xlsx",true);
wb.write(out); 
out.close();
    }           
}

you need to create output Stream after you created all cells,then write them to the file. see the codes in details.
