In case you want to do this in java rather than using the ASP examples that itsvtk gave:

You could use the hssf part of poi in a servlet:

http://jakarta.apache.org/poi/hssf/

Let me know if you need any further code examples.

When you need to set content type to something other that text/html, I think it is better to use a servlet.

In one project where we needed this functionality,we used a servlet.Set the content type to application/vnd.ms-excel.
Created a tab delimited string for the required columns and sent the string.

Convert your code from JSP to ASP is very easy.... Almost most of the code will work as it is...

Hi Abhijit, I'd use something along the following lines:

// Open workbook
HSSFWorkbook wb = new HSSFWorkbook(new POIFSFileSystem(new FileInputStream("c:\\temp\\blank.xls")));

// Edit workbook
HSSFSheet sheet = wb.getSheet("Sheet1");
HSSFRow row = sheet.getRow(9);
HSSFCell cell = row.getCell((short) 2);

// Get Value
double value = cell.getNumericCellValue();
// or
String value = cell.getStringCellValue();

Hope this helps.
