how do i set up an excel file to read spread sheets

Do you mean to use automation to manipulate spreadsheets as opposed to
importing them using TransferSpreadsheet? If so, this code contains what you
need to open a spreadsheet. That is done in the GetExcel Sub. If you want
to create a new spreadsheet, read up on the CreateObject method in VBA Help.

Paste this code into a standard module. Mine is named modExcelRoutines. I
really don't use the GetExcel sub, but it is a good basis for learning how to
open a spreadsheet. Also, to manipulate an Excel object, you will need to
study up on the Excel Object model. I have found using the Object Browser in
VBA is a great way to do that.

Option Compare Database
Option Explicit

' Declare necessary API routines:
Declare Function FindWindow Lib "user32" Alias _
"FindWindowA" (ByVal lpClassName As String, _
ByVal lpWindowName As Long) As Long

Declare Function SendMessage Lib "user32" Alias _
"SendMessageA" (ByVal Hwnd As Long, ByVal wMsg As Long, _
ByVal wParam As Long, _
ByVal lParam As Long) As Long

Sub GetExcel()
Dim MyXL As Object ' Variable to hold reference
' to Microsoft Excel.
Dim ExcelWasNotRunning As Boolean ' Flag for final release.

' Test to see if there is a copy of Microsoft Excel already running.
On Error Resume Next ' Defer error trapping.
' Getobject function called without the first argument returns a
' reference to an instance of the application. If the application isn't
' running, an error occurs.
Set MyXL = GetObject(, "Excel.Application")
If Err.Number 0 Then ExcelWasNotRunning = True
Err.Clear ' Clear Err object in case error occurred.

' Check for Microsoft Excel. If Microsoft Excel is running,
' enter it into the Running Object table.
DetectExcel

' Set the object variable to reference the file you want to see.
Set MyXL = GetObject("c:\vb4\MYTEST.XLS")

' Show Microsoft Excel through its Application property. Then
' show the actual window containing the file using the Windows
' collection of the MyXL object reference.
MyXL.Application.Visible = True
MyXL.Parent.Windows(1).Visible = True
' Do manipulations of your file here.
' ...
' If this copy of Microsoft Excel was not running when you
' started, close it using the Application property's Quit method.
' Note that when you try to quit Microsoft Excel, the
' title bar blinks and a message is displayed asking if you
' want to save any loaded files.
If ExcelWasNotRunning = True Then
MyXL.Application.Quit
End If

Set MyXL = Nothing ' Release reference to the
' application and spreadsheet.
End Sub

Sub DetectExcel()
' Procedure dectects a running Excel and registers it.
Const WM_USER = 1024
Dim Hwnd As Long
' If Excel is running this API call returns its handle.
Hwnd = FindWindow("XLMAIN", 0)
If Hwnd = 0 Then ' 0 means Excel not running.
Exit Sub
Else
' Excel is running so use the SendMessage API
' function to enter it in the Running Object Table.
SendMessage Hwnd, WM_USER + 18, 0, 0
End If
End Sub

I'd suggest asking in a newsgroup related to Excel.

This newsgroup is for questions about Access, the database product that's
part of Office Professional.
