Font size small (4pt) using enhancedspreadsheet desformat even though designed as 12pt

My client often uses the enhancedspreadseet desformat in Oracle reports 12,2,1,3 to create spreadsheet output.

I looked at the design and the simple tabular reports have the font defined as courier new 12 pt.

The page width is ranges from 8 to 36 inches to accommodate the large number of columns in some reports.

When the report is run with enhancedspreadsheet option, the font size in the resultant spreadsheet is tiny - 4 pts.

Is there a way to preserve the font size provided at design time for enhancedspreadsheet reports?

Thanks.
