hi!
It's very very simple to do
Just download load the POI project (poi-2.5.1-final-20040804.jar file) from the Apache Jakarta site - it's a open source project
just put the jar file into your class path.
import the packages which i mentioned below...(it's a minimum requirement)
import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.hssf.*;
import org.apache.poi.poifs.filesystem.*;
and refer the document (for coding) which include in that jar file itself... they included the example like Openning the workbook and fetching the rows....
so u develop the rest of the things...
Note: download bin & src.
