Problem with down load excell when renderer column

I have a data grid where one of the columns is created using a renderer (numeric type). When I download this data grid as an Excel file, this column appears as text format.
Desired outcome: This column should be in numeric format to enable numeric calculations in Excel.
Thanks.
The code is shown below:
