No, but you could create a macro that would open each of your .csv files, format
it the way you want, save it (and repeat).
Start a new workbook and record a macro when you open one of the CSV files.
Continue recording when you format it.
Then you can tweak the macro to look more like:
Option Explicit
Sub testme()
Dim myFileNames As Variant
Dim iCtr As Long
Dim wkbk As Workbook
Dim NewFileName As String
myFileNames = Application.GetOpenFilename _
("CSV Files, *.csv", MultiSelect:=True)
If IsArray(myFileNames) = False Then
Exit Sub 'user hit cancel
End If
For iCtr = LBound(myFileNames) To UBound(myFileNames)
NewFileName _
= Left(myFileNames(iCtr), Len(myFileNames(iCtr)) - 4) & ".xls"
Set wkbk = Workbooks.Open(Filename:=myFileNames(iCtr))
'do your formatting
'save the workbook
Application.DisplayAlerts = False
wkbk.SaveAs Filename:=NewFileName
Application.DisplayAlerts = True
wkbk.Close savechanges:=False
Next iCtr
End Sub
The multiselect stuff allows you to click on the first and ctrl-click on
subsequent in the File|open dialog. That way you just select the ones you want
to convert.
