Jeg fandt langt om længe noget på nettet.
http://www.exceltip.com/st/Read_information_from_a_closed_workbook_using_VBA_in_Microsoft_Excel/473.htmlWith the macros below you can read values and text from cells in closed workbooks.
The example macros shows how you can read the value from cell A1 in Sheet1 in all workbooks in a given folder.
Sub ReadDataFromAllWorkbooksInFolder()
Dim FolderName As String, wbName As String, r As Long, cValue As Variant
Dim wbList() As String, wbCount As Integer, i As Integer
FolderName = "C:\Foldername"
' create list of workbooks in foldername
wbCount = 0
wbName = Dir(FolderName & "\" & "*.xls")
While wbName <> ""
wbCount = wbCount + 1
ReDim Preserve wbList(1 To wbCount)
wbList(wbCount) = wbName
wbName = Dir
Wend
If wbCount = 0 Then Exit Sub
' get values from each workbook
r = 0
Workbooks.Add
For i = 1 To wbCount
r = r + 1
cValue = GetInfoFromClosedFile(FolderName, wbList(i), "Sheet1", "A1")
Cells(r, 1).Formula = wbList(i)
Cells(r, 2).Formula = cValue
Next i
End Sub
Private Function GetInfoFromClosedFile(ByVal wbPath As String, _
wbName As String, wsName As String, cellRef As String) As Variant
Dim arg As String
GetInfoFromClosedFile = ""
If Right(wbPath, 1) <> "\" Then wbPath = wbPath & "\"
If Dir(wbPath & "\" & wbName) = "" Then Exit Function
arg = "'" & wbPath & "[" & wbName & "]" & _
wsName & "'!" & Range(cellRef).Address(True, True, xlR1C1)
On Error Resume Next
GetInfoFromClosedFile = ExecuteExcel4Macro(arg)
End Function
