Hi Balaji
If you are taking the values from the excel sheet and stroing the report in the excel sheet you can do that by using the datatable object.
You can import both the sheets and compare them
If you want to compare with the runtime values of the Java Application You can use the GETROProperty of the object and store it in a string and you can compare
I think i answered your question if you want further clarrifications feel free to ask
