Hi Bhargav,
As per the documentation:
"Under "Select a priority for saving to MS Excel", select the option that best fits your needs:
u2022 If you want to display the data in a format that is similar to working in Web Intelligence, then
choose Prioritize the formatting of the documents.
u2022 If you want to display the data in a text format, then choose Prioritize easy data processing in
Excel."
"Prioritize easy data processing in Excel." is not a sure shot solution; however, you can give it a try.

Yuvraj
