Question

我需要将文本文件转换为Excel文件。我找到了关于此的文章，但我的要求没有什么不同，所以我不知道。

我的文本文件包含此格式的行

Jun 13 07:35:08 mail dovecot: pop3-login: Login: user=<veena,.patel@test.com>, method=PLAIN, rip=102.201.122.131, lip=103.123.113.83, mpid=33178, session=<Wfdfdfcxvc>

我想创建包含四列的Excel文件： -

第一栏包括上述行的“Jun 13 07:35:08”
第二列包含上面一行的“pop3”
第三栏包括“veena，.patel @ test.com”
和第四栏包括“102.201.122.131”

Excel中不需要所有其他数据。我怎样才能做到这一点？我知道这不是我想要的。我应该先写一些关于我先尝试过的代码，但实际上我并不知道。

如果你要接受VBA-在你看过一些教程之后 - 你需要这种方法。
1。通过EOF method.获取文本文件
2。使用REGEX的每个所需条件的UDF将是我的方法 - 提示：您可以检查您的正则表达式逻辑here - 。
以下是提取电子邮件的示例：

Function UserInString(StringToAnalyze As String) As String
Dim regex As Object: Set regex = CreateObject("VBScript.RegExp")
Dim Regexmatches As Variant
Dim ItemMatch As Variant
    With regex
      .Pattern = "[a-z]{1,99}[,][.][A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}"
      .Global = True
    End With

    If regex.Test(StringToAnalyze) = True Then 'there's a user in the string! ' 1. If regex.Test(StringToAnalyze) = True
    Set Regexmatches = regex.Execute(StringToAnalyze)
    For Each ItemMatch In Regexmatches
      UserInString = IIf(UserInString = "", ItemMatch, ItemMatch & "," & UserInString)
    Next ItemMatch
    Else ' 1. If regex.Test(StringToAnalyze) = True
    UserInString = "There's no user in the string!"
    End If ' 1. If regex.Test(StringToAnalyze) = True
End Function
