I found this macro in the forums and it works great. What is does is
create a seperate CSV file for every row in the workbook.

What I would like to do though is create a file for every 25 rows. I
also would like to make the files .XLS, not .CSV.

Can anyone assist in tweaking this macro for me? Thanks!

Dim curWks As Worksheet
Dim newWks As Worksheet


Dim iRow As Long
Dim FirstRow As Long
Dim LastRow As Long


Set curWks = Worksheets("sheet1")
Set newWks = Workbooks.Add(1).Worksheets(1)


With curWks
FirstRow = 2 'headers in row 1
LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row


.Rows(1).Copy
With newWks.Range("A1")
.PasteSpecial Paste:=xlPasteValues
.PasteSpecial Paste:=xlPasteFormats
End With


For iRow = FirstRow To LastRow
.Rows(iRow).Copy
With newWks.Range("a2")
.PasteSpecial Paste:=xlPasteValues
.PasteSpecial Paste:=xlPasteFormats
End With
newWks.Parent.SaveAs _
Filename:="C:\temp\" & Format(iRow, "0000") & ".csv", _
FileFormat:=xlCSV
Next iRow
End With


newWks.Parent.Close savechanges:=False


End Sub
