I'm no whiz at batch files, but what you're trying to do sounds like it should be easy to do as a macro. If you want it to be configurable, or save the file in a specific location you could do that in the VBA code, but if you just want to grab the same set of cells, delete the top row and save it as a csv file then try this code (you can modify the file location to fit your needs):
Application.CutCopyMode = False
ChDir "C:\Documents and Settings\Default\Desktop"
ActiveWorkbook.SaveAs Filename:= _
"C:\Documents and Settings\Default\Desktop\Book1.csv", FileFormat:=xlCSV, _
