Sorry,
I found how to make it bold, numberformatting and so on, but didn't find simple fontsize.
so the Excel-Sheet is always on 8.5 pt, which I would like to change to 10 pt.
Thanks for your help!

You can change the CellFormat.Font.Height on a row, column, or cell. However, the font height is in twips, or 20ths of a point, so if you want the font to be 10pt font, set the height to 200.
