从电子邮件(或几千封电子邮件)中提取数据[基于交换]

获取Exchange邮箱中的邮件有很多不同的方法,但由于这似乎是您只希望运行一次以提取数据的方法,因此我建议您编写一个vba宏以在Outlook内部运行(在Outlook中打开了有问题的Exchange邮箱)。迭代特定邮箱中的邮件并从中读取正文文本非常容易。然后你可以用你想要的东西写一个文本文件。

这是我用的代码……

Private Sub btnGo_Click()
  If ComboBox1.SelText <> "" Then
    Dim objOutlook As New Outlook.Application
    Dim objNameSpace As Outlook.NameSpace
    Dim objInbox As MAPIFolder
    Dim objMail As mailItem

    //Get the MAPI reference
    Set objNameSpace = objOutlook.GetNamespace("MAPI")

    //Pick up the Inbox
    Set objInbox = objNameSpace.GetDefaultFolder(olFolderInbox)
    For Each objFolder In objInbox.Folders
       If (objFolder.Name = ComboBox1.SelText) Then
          Set objInbox = objFolder
       End If
    Next objFolder

    //Loop through the items in the Inbox
    Dim count As Integer
    count = 1

    For Each objMail In objInbox.Items
       lblStatus.Caption = "Count: " + CStr(count)
       If (CheckBox1.Value = False Or objMail.UnRead = True) Then
          ProcessMailItem (objMail.Body)
          count = count + 1
          objMail.UnRead = False
       End If
    Next objMail
  End If
End Sub

Private Sub ProcessMailItem(strBody As String)
   Open "C:\file.txt" For Append As 1

   Dim strTmp As String
   strTmp = Replace(strBody, vbNewLine, " ")
   strTmp = Replace(strTmp, vbCrLf, " ")
   strTmp = Replace(strTmp, Chr(13) & Chr(10), " ")
   strTmp = Replace(strTmp, ",", "_")

   //Extra Processing went here (Deleted for brevity)
   Print #1, strTmp
   Close #1

End Sub

Private Function Strip(strStart As String, strEnd As String, strBody As String) As String
   Dim iStart As Integer
   Dim iEnd As Integer

   iStart = InStr(strBody, strStart) + Len(strStart)
   If (strEnd = "xxx") Then
      iEnd = Len(strBody)
   Else
      iEnd = InStr(strBody, strEnd) - 1
   End If

   Strip = LTrim(RTrim(Mid(strBody, iStart, iEnd - iStart)))
End Function


Private Sub UserForm_Initialize()
  Dim objOutlook As New Outlook.Application
  Dim objNameSpace As Outlook.NameSpace
  Dim objInbox As MAPIFolder
  Dim objFolder As MAPIFolder

  //Get the MAPI reference
  Set objNameSpace = objOutlook.GetNamespace("MAPI")

  //Pick up the Inbox
  Set objInbox = objNameSpace.GetDefaultFolder(olFolderInbox)

  //Loop through the folders under the Inbox
  For Each objFolder In objInbox.Folders
    ComboBox1.AddItem objFolder.Name
  Next objFolder
End Sub
