Hi,

you can try like this 

string excel2007filename= Server.MapPath("file.xlsx");

string excel2003filename=Server.MapPath("file1.xlsx");

byte[] buffer=File.ReadAllBytes(excel2007filename)

File.WriteAllBytes(buffer,excel2003filename);

You need to work with Excel Com Component. The above code is just a kind of Copy-Paste code with the change in name. Probably this thread can assist you in that.

Why?  Excel 2003 can open Excel 2007 files.  The converter was released years ago in Windows update.

Thanks deepak, this thread seems like opening a excel file through code. But the problem is that my Hosting provider is supporting Microsoft ACE 12.0 driver (Excel 2007 support). I have to handle it with Jet driver (Excel 2003) thats why I want to convert Excel 2007 to Excel 2003 so that my application can handle both versions of Excel.
