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");

Excel sheet is not opening in server side but it is opening in local

String filepath="";
try {
//String filename=file_name.replace('/','_');
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet(file_name);
HSSFRow rowhead = sheet.createRow((short) 0);
filepath=prop.getProperty("file_store_path")+file_name+timeStamp+".xls";
FileOutputStream fileOut = new FileOutputStream(filepath);
/* rowhead.createCell((short) 1).setCellValue("Domain ID");*/
rowhead.createCell((short) 0).setCellValue("Person ID");
rowhead.createCell((short) 1).setCellValue("Domain ID");
rowhead.createCell((short) 2).setCellValue("First Name");
rowhead.createCell((short) 3).setCellValue("Last Name");
rowhead.createCell((short) 4).setCellValue("Email Address");
rowhead.createCell((short) 5).setCellValue("SBU");
int i = 1;
while (rs.next()){
HSSFRow row = sheet.createRow((short) i);
/* row.createCell((short) 0).setCellValue(rs.getString("domain_id"));*/
row.createCell((short) 0).setCellValue(rs.getString("person_id"));
row.createCell((short) 1).setCellValue(rs.getString("domain_id"));
row.createCell((short) 2).setCellValue(rs.getString("first_name") );
row.createCell((short) 3).setCellValue(rs.getString("last_name"));
row.createCell((short) 4).setCellValue(rs.getString("email_address"));
row.createCell((short) 5).setCellValue(rs.getString("business_unit"));
i++;
}
workbook.write(fileOut);
fileOut.close();
System.out.println("XLS done!!");
}
I am having some issue with excel sheet exporting in Server side. The sheet is working fine in local but not working when deploying in Server. I am using XSSF format here (I have also used HSSF but getting different issue with that). I have attached the error message here.
How can I solve this issue?
The error I am getting is
java.lang.IndexOutOfBoundsException

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++) {

cell.setCellValue(lstUserDetail1.getStrUserName());
cell.setCellValue(lstUserDetail1.getStrEMail());

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);
}

Generate excel file using java with different column width

I am doing a java application (J2SE) which I have to generate a excel document (.xls). I did generate the file but I am not able to change the cell width dynamically according to the content which is having the maximum length in the same cell.
Here is my coding...
try {
ResultSet rs = com.dss.system.DBORCL.search("sql statement");
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("Excel Sheet");
HSSFRow rowhead = sheet.createRow((short) 0);
rowhead.createCell((short) 0).setCellValue("Site");
rowhead.createCell((short) 1).setCellValue("Part No");
rowhead.createCell((short) 2).setCellValue("Part Description");
int index = 1;
while (rs.next()) {
HSSFRow row = sheet.createRow((short) index);
row.createCell((short) 0).setCellValue(rs.getString("site"));
row.createCell((short) 1).setCellValue(rs.getString("part_no"));
row.createCell((short) 1).setCellValue(rs.getString("description"));
index++;
}
FileOutputStream fileOut = new FileOutputStream("F:\\IFS\\IFSDOC" + txtPLCode.getText() + "[" + currentDate + "-" + usesecond + "]" + ".xls");
wb.write(fileOut);
fileOut.close();
System.out.println("Data is saved in excel file.");
// rs.close();

sheet.autoSizeColumn(0) //for first column
sheet.autoSizeColumn(1) //for second column ... etc

Save As DialogueBox is not working in servlet response.setHeader

I am exporting data displayed in jqgrid into .excel file by clicking button .
Here is my code for export to excel button click..
$('#excel').click(function(){
var fromdate=$('#fromdate').val();
var todate=$('#todate').val();
if(fromdate && todate)
{
var URL='excel?fromdate='+$('#fromdate').val()+'&todate='+$('#todate').val();
$.ajax({
url:URL,
type:'GET',
success:function(data){
alert('Exported To Excel');
}
});
}
});
Now this button will direct to excel.java page which is servlet.Below is my exceljava page code .Now Asper my need when the user click on export to excel button a openwith and save as dialogue box should popup which gives user ability to give desired name and save to desired positionbut it is not happening with this code.plz point out my mistake ..
excel.java
try {
response.setHeader("Content-Type", "application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment; filename=excel.xls");
String datum1 = request.getParameter("fromdate");
String datum2 = request.getParameter("todate");

Date date = sdfSource.parse(datum1);
Date date2 = sdfSource.parse(datum2);

datum1 = sdfDestination.format(date);
System.out.println(datum1);
datum2 = sdfDestination.format(date2);
