   'The purpose of this is to save typing Sheets("Sheet1")
   'over and over again
   Set Ws = Sheets("Sheet1")

   'Set the Path to the database. This line is useful because
   'if your database is in another location, you just need to change
   'it here and the Path Variable will be used throughout the code
   Path = "c:\msoffice\access\samples\northwind.mdb"

   'This set of code will activate Sheet1 and clear any existing data
   'After clearing the data it will select cell A1

   'Set the Database, and RecordSet  This Table exists in the database
   Set Db = Workspaces(0).OpenDatabase(Path, ReadOnly:=True)

   'This will set the RecordSet to all records in the Customers table
   Set Rs = Db.OpenRecordset("Customers")

   'You could instead set the RecordSet to, for example, the records
   'where the Country Code is "UK", without quotes. To do this, replace
   'the line above: Set Rs = Db.OpenRecordset("Customers") with the
   'Set Rs = _
   'Db.OpenRecordset("SELECT * FROM Customers WHERE Country = 'UK';")

   'This loop will collect the field names and place them in the first
   'row starting at "A1"
   For i = 0 To Rs.Fields.Count - 1
      Ws.Cells(1, i + 1).Value = Rs.Fields(i).Name
   Next I

   'The next line simply formats the headers to bold font
