This macro exports the values or formulas and charts from a worksheet range to a new workbook/worksheet:

Sub ExportRangeAsWB(SourceRange As Range, TargetFile As String, SaveValuesOnly As Boolean)
' Exports the data in the range SourceRange to
' the workbook TargetFile in standard workbook format
' Examples:
' ExportRangeAsWB Range("A1:M25"), "C:\FolderName\TargetWB.xls", True
' ExportRangeAsWB Worksheets("Sheet2").Range("A1:M25"), "C:\FolderName\TargetWB.xls", True

Dim r As Long, c As Integer, tr As Long
Dim TargetWB As Workbook, A As Integer
