我有一个由建模程序创建的 800 多页文档。本文档主要由一系列编号的句子（未编号的列表）组成。可以有 10,000 个编号的行，这些行将被转换为 5000-7000 个不同长度的编号列表。

VBA for Word 脚本（见下文）搜索后面的第一个编号段落和未编号段落，然后查找未编号段落之前的最后一个编号段落，然后将范围转换为编号列表。重复此序列直到文档结束。

该过程按预期工作。问题是，它消耗 65-95% 的 CPU、大部分物理内存，并且需要 5-15 小时才能运行。

任何关于将性能提高至少一个数量级（至少是一半或四分之一的时间）的想法将不胜感激。

这可能是一种解决方案。您可能需要根据您的文档调整正则表达式模式。性能似乎合理：

Option Explicit

Public Sub ConvertDocument()

    Dim vParagraph As Paragraph
    Dim vRegExp As New RegExp

    vRegExp.Pattern = "^[0-9]+.\t"

    Application.ScreenUpdating = False
    For Each vParagraph In ActiveDocument.Paragraphs
        If vRegExp.Test(vParagraph.Range.Text) Then
            vParagraph.Range.ListFormat.ApplyNumberDefault
        End If
        ActiveDocument.UndoClear
        DoEvents
    Next
    Application.ScreenUpdating = True

End Sub

下面是我使用的测试数据生成器；更改 for 循环以生成更多或更少的测试数据。

Public Sub TestDataPopulate()

    Dim vCounter As Long
    Dim vParagraph As Paragraph

    Application.ScreenUpdating = False
    For vCounter = 1 To 50
        Set vParagraph = ActiveDocument.Paragraphs.Add
        vParagraph.Range.Text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt " & _
                                "ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco " & vbCrLf & _
                                "Lorem ipsum dolor" & vbCrLf & _
                                vbCrLf & _
                                "1." & vbTab & "Lorem ipsum dolor sit amet" & vbCrLf & _
                                "2." & vbTab & "consectetur adipiscing elit" & vbCrLf & _
                                "3." & vbTab & "sed do eiusmod tempor incididunt" & vbCrLf & _
                                vbCrLf
        ActiveDocument.UndoClear
    Next
    Application.ScreenUpdating = True

End Sub
