Reports & Discoverer :: Any Way To Pass Delimiter In Builder

I need to produce Excel spreadsheet from report builder.currently I am getting a format like,

ProductID;Count;CountUnique;
1001;12;16;
1002;11;6;
1004;16;666;
1006;60;86;

This format when opened in Excel does not group in separate columns resulting in all getting mixed up.I am looking a format like,

ProductID,Count,CountUnique,
1001,12,16,
1002,11,6,
1004,16,666,
1006,60,86,

This opens up clearly on excel. items like Product,Count are shown on separate columns along with the value.I am still looking into delimited formatting.
