how to write values obtained using List and Iterator in a excel file using apache poi and selenium webdriver

Hi I need to store a list of values which I obtained from a webpage using List and Iterator using selenium webdriver, I want to store/write those values in a excel sheet
Link of the website:https://www.zigwheels.com/used-car
I have obtained a list of values under popular car models and I need to store it in a excel sheet using apache poi
Coding starts here:
WebElement li=
driver.findElement(By.xpath("//span[text()='Brand and Model']//parent::div//followingsibling::div//child::div[4]/ul"));
List<WebElement> alloptions=li.findElements(By.tagName("li"));
Iterator<WebElement> itr=alloptions.iterator();
while(itr.hasNext()) {
WebElement lii=itr.next();
String list=lii.getText();
System.out.println(list);

Create file, than sheet, then rows, and fill cells in row:
public void CreateNew_Make_BeckupFile() throws IOException
{
String filePath = "filepath.xls";
File f = new File(filePath);
if (!(f.exists() && f.isFile()))
{
Workbook workbook = new XSSFWorkbook(); // new HSSFWorkbook() for generating `.xls` file
/*
* CreationHelper helps us create instances of various things like DataFormat,
* Hyperlink, RichTextString etc, in a format (HSSF, XSSF) independent way
*/
CreationHelper createHelper = workbook.getCreationHelper();
for (int p = 0; p < listaTimova.size(); p++) {
// Create a Sheet
// Sheet sheet = workbook.createSheet("Employee");
SheetCreation (workbook, p);
}
// Write the output to a file
FileOutputStream outputStream = new FileOutputStream(filePath);
workbook.write(outputStream);
// Closing the workbook
workbook.close();
outputStream.close();
}
public void SheetCreation (Workbook workbook, int teamNumber)
{
CreationHelper createHelper = workbook.getCreationHelper();
Sheet sheet = workbook.createSheet("Sheet Name");
// Create a Font for styling header cells
Font headerFont = workbook.createFont();
headerFont.setBold(true);
headerFont.setFontHeightInPoints((short) 14);
headerFont.setColor(IndexedColors.BLUE.getIndex());
// Create a CellStyle with the font
CellStyle headerCellStyle = workbook.createCellStyle();
headerCellStyle.setFont(headerFont);
// Create a Row
Row headerRow = sheet.createRow(0);
// Create cells
for (int i = 0; i < columns.length; i++) {
Cell cell = headerRow.createCell(i);
cell.setCellValue(columns[i]);
cell.setCellStyle(headerCellStyle);
}
headerFont.setColor(IndexedColors.BLACK.getIndex());
headerCellStyle.setFont(headerFont);
for (int u = 0; u < listaTimova.get(teamNumber).listaIgracaTima.size(); u++)
{
Row headerRow2 = sheet.createRow(u + 1);
**RowCreation(headerRow2, teamNumber, u, 0);**
}
for(int i = 0; i < columns.length; i++)
{
sheet.autoSizeColumn(i);
}
}
**public void RowCreation(Row row, int teamNumber, int playerNumber, int cellNumber)**
{
row.createCell(cellNumber, CellType.STRING).setCellValue("Any value for cell");
row.createCell(cellNumber+1, CellType.STRING).setCellValue("next cell in row value...");
}

Get a row from excel file which contains a value

I need to get a row which contains value in column 1 in my excel file using Java
I need to search column when find cell then get the row which contains searched cell

FileInputStream fis = new FileInputStream(new File(filepath));
XSSFWorkbook workBook = new XSSFWorkbook (fis);
XSSFSheet sheet = workBook.getSheetAt (0);
List<XSSFRow> filteredRows = new ArrayList<XSSFRow>();
Iterator<Row> rows= sheet.rowIterator();
while (rows.hasNext ()){
XSSFRow row = (XSSFRow) rows.next ();
for(Cell cell : row) {
if(cell.getColumnIndex() == 1) {
// process a cell in column 1
if (cell.getStringCellValue()!=null){
String val = cell.getStringCellValue();
if (val.equals(""))
//You will find valid value in variable val
}
}
}

Write XLSX file to external storage in Android

I'm trying to create and save an XLSX file into my Download folder, but even if it doesn't gives error, nothing gets saved. This is the code:
private void importIntoExcel() throws IOException {
String[] columns = { "Numero Test", "Genere", "Data di nascita", "Data del test"};
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("RiepilogoTest");
Font headerFont = workbook.createFont();
headerFont.setBold(true);
headerFont.setFontHeightInPoints((short) 14);
headerFont.setColor(IndexedColors.RED.getIndex());
CellStyle headerCellStyle = workbook.createCellStyle();
headerCellStyle.setFont(headerFont);
// Create a Row
Row headerRow = sheet.createRow(0);
for (int i = 0; i < columns.length; i++) {
Cell cell = headerRow.createCell(i);
cell.setCellValue(columns[i]);
cell.setCellStyle(headerCellStyle);
}
// Create Other rows and cells with contacts data
int rowNum = 1;
// Write the output to a file
FileOutputStream fileOut = new FileOutputStream(new File(Environment.getExternalStorageDirectory().toString()+"risultatiTest.xlsx"));
workbook.write(fileOut);
fileOut.close();
}

Create Excel with Java format text

When I download Excel, I get cells with format Numbers I need format text en all Cells.
try {
XSSFSheet sheet = workbook.createSheet(eyelash);
XSSFFont font = workbook.createFont();
font.setColor(HSSFColor.WHITE.index);
XSSFCellStyle style = workbook.createCellStyle();
style.setFont(font);
style.setFillPattern(FillPatternType.SOLID_FOREGROUND);
style.setFillForegroundColor(HSSFColor.RED.index);
String[] header = { "name","surname"};
XSSFRow rowhead = sheet.createRow((short) 0);
XSSFCell cell;
int cellnum = 0;
for (int i = 0; i < header.length; i++) {
cell = rowhead.createCell(cellnum);
cell.setCellValue(header[i]);
cell.setCellStyle(style);
cell.setCellType(XSSFCell.CELL_TYPE_STRING);
cellnum++;
}
if (data) {
int myRowData = 1;
XSSFRow row = sheet.createRow((short) myRowData);
ArrayList<GasNomination> list = this.select();
for (int i = 0; i < list.size(); i++) {
row.createCell(0).setCellValue(list.get(i).name());
row.createCell(1).setCellValue(list.get(i).surname());
myRowData++;
row = sheet.createRow((short) myRowData);
}
}
} catch (Exception ex) {
}
I tried cell.setCellType(XSSFCell.CELL_TYPE_STRING);
But when I open my Excel I see formatcell type numeric ...

You can use DataFormatter,
System.out.println("started");
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet();
XSSFRow row = sheet.createRow(0);
XSSFCell cell = row.createCell(0);
cell.setCellValue(3.14159);
cell.setCellType(XSSFCell.CELL_TYPE_STRING);
XSSFDataFormat format = workbook.createDataFormat();
XSSFCellStyle style = workbook.createCellStyle();
style.setDataFormat(format.getFormat("Text"));
cell.setCellStyle(style);
workbook.write(new FileOutputStream("Test.xlsx"));
System.out.println("finished");

How to populate an Excel sheet with the data from an arraylist using Apache POI

How to populate an Excel sheet with the data from an arraylist using Apache POI?
public String exporttoexcel(UserDetails user) throws Exception {
System.out.print("Inside serviceimpl.ExportToExcel method");
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("new sheet");
HSSFRow row = sheet.createRow((short)0);
List<UserDetails> lstUserDetail = getUserDetailList();
for (int i=0; i<lstUserDetail.size(); i++) {
UserDetails lstUserDetail1 = lstUserDetail.get(i);
String a=lstUserDetail1.getStrUserName();
System.out.print("useridddd is"+a);
HSSFCell cell = row.createCell((short) 0);
cell.setCellValue(lstUserDetail1.getStrUserId());
cell.setCellValue(lstUserDetail1.getStrUserName());
cell.setCellValue(lstUserDetail1.getStrEMail());
cell.setCellValue(lstUserDetail1.getStrUserStatus());
cell.setCellValue(lstUserDetail1.getStrUserRole());
}
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
System.out.print("file created");
return null;
}

You have created one single cell and entering all the values in a same single cell each time.
You need to take two loops. One for iterating through row and another for iterating through column. Though I have not tested... use code like below.
for(int RowNum=0; RowNum<MaxArrayLength;RowNum++){
HSSFRow row = sheet.createRow(RowNum);
for(int ColNum=0; ColNum<ArrayWidth;ColNum++){
HSSFCell cell = row.createCell(ColNum);
cell.setCellValue(ArrayList[RowNum][ColNum]);
}
}

FileOutputStream fileOut = new FileOutputStream("your file path");
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = workbook.createSheet("sheet name");
try {
//creating the headers
Row row = sheet.createRow(0);
row.createCell(0).setCellValue("name");
row.createCell(1).setCellValue("Name1");
row.createCell(2).setCellValue("name2");
//get the list which u want
List<String> list = getNamesList();
int rowNum = 1;
for (Name name : list ) {
Row row1 = sheet.createRow(rowNum++);
row1.createCell(0).setCellValue((name.get..));
}
workbook.write(fileOut);
}
