[AccessD] Access To Excel via a CSV File

Can any of you Access/Excel gurus help here please.
I need to create a csv spreadsheet by code.  When it is complete, I need to
put formatting on it. Ie,make columns into Currency Types. Bold some Rows,
set some bacground colours, etc.
I have got as far as creating the CSV ok but then I am stumped.
Any advice most welcome.
