Hi Friend,

Try the following code:

<[email protected] import="java.io.*"%>
<[email protected] import="java.util.*"%>
<[email protected] import=" org.apache.poi.hssf.usermodel.HSSFSheet"%>
<[email protected] import=" org.apache.poi.hssf.usermodel.HSSFWorkbook"%>
<[email protected] import=" org.apache.poi.hssf.usermodel.HSSFRow"%>
<[email protected] import=" org.apache.poi.hssf.usermodel.HSSFCell"%>
<%
short p=1;
String filename ="C:/excelFile.xls";
if (filename != null && !filename.equals("")) {
try{
FileInputStream fs =new FileInputStream(filename);
HSSFWorkbook wb = new HSSFWorkbook(fs);
for (int k = 0; k < wb.getNumberOfSheets(); k++){
HSSFSheet sheet = wb.getSheetAt(k);
int rows = sheet.getPhysicalNumberOfRows();
for (int r = 1; r < rows; r++){
HSSFRow row = sheet.getRow(r);
if (row != null) {
int cells = row.getPhysicalNumberOfCells();
%><br><%
HSSFCell cell = row.getCell(p);
if (cell != null) {
String value = null;
switch (cell.getCellType()){
case HSSFCell.CELL_TYPE_FORMULA :
value = "FORMULA ";
break;

case HSSFCell.CELL_TYPE_NUMERIC :
value = ""+cell.getNumericCellValue();
break;

case HSSFCell.CELL_TYPE_STRING :
value = cell.getStringCellValue();
break;

default :
}
%><%= value %><%
}
}
}
}
}
catch (Exception e){
e.printStackTrace();
}

}
%>

In the above code, we have passed the 'email' column index to the method row.getCell(p) where variable p of short type refers to column index.

Hope that it will be helpful for you.
Thanks
