How to create an excel file in android?

I have to create an excel file programatically. Is there is any API to create an excel file or some other ways?

EDIT on 7th Nov 2011

I tried example Create an Excel Spreadsheet from this link Create an Excel spredsheet
and I am getting NullPointerException at

workbook.write();
, Using this I can create excel file on SD card, but when I open that excel file using MS office 2007 I am getting
Unable to read file
message

Here the stack trace,
ExcelStudy
is my activity that uses
WriteExcel
class

You can use jxl-2.6.12.jar, to create excel sheet in Android.

Here is Java Excel API Tutorial, and Documentation here.
