Here is a snippet of code taken from a code I use for something similar – it should help:
Option Explicit
Sub Exportmacro()
Dim rCell As Range, rRng As Range 'define loop names
Dim NewCaseFile As Workbook 'give a name to new work book for duplicate sheet
Dim wks As Worksheet 'name of the copy of feedback
Dim sPath As String
sPath = MacScript("(path to desktop folder as string)")
'turn off screen
With Application
'.ScreenUpdating = False ‘only removed while testing
'.EnableEvents = False
'.Calculation = xlCalculationManual ‘disabled for the moment
End With
'Student numbers in cells A7:A160 WARNING SET TO 3 STUDENTS ONLY FOR TEST
Set rRng = Worksheets("studentlist").Range("A7:A9")
For Each rCell In rRng '<--| loop through "students" range
'now open new workbook
Set NewCaseFile = Workbooks.Add
'now save as xls with student number as filename Filename:=sPath & rCell.Value & ".xlsx"
ActiveWorkbook.SaveAs Filename:=rCell.Value & ".xlsx", FileFormat:=xlOpenXMLWorkbook, CreateBackup:=False
'now close duplicate file
ActiveWorkbook.Close False
Next rCell '<-- next student number
End With '<-- once all done
'turn screen back on
Application.ScreenUpdating = True
Application.DisplayAlerts = True
End Sub
