我正在编写 VBA 宏，它将在适当的情况下转换字符串，但有一些限制。

开头文字：

  1. DTest dk;G3Gj
  2. _dsc0148A
  3. 1陶器2
  4. Articiart147
  5. 如果你不需要它
  6. Pressed_pleasure
  7. 在地上

期望的结果：

  1. Dtest Dk;G3gj
  2. _Dsc0148a
  3. 1陶器2
  4. Articiart147
  5. 如果你不需要它
  6. Pressed_Pleasure
  7. 在地上

尝试1：

Sub ChangePCase()
 rownum = 2
 colnum = 1

 ActiveSheet.Range("a2", ActiveSheet.Range("a2").End(xlDown)).Select

     For Each Cell In Selection
       mystr = Cells(rownum, colnum).value

        Text = WorksheetFunction.Proper(mystr)
        Cells(rownum, colnum + 1) = Text
        rownum = rownum + 1
     Next
End Sub

结果

  1. Dtest Dk;G3Gj
  2. _Dsc0148A
  3. 1陶器2
  4. Articiart147
  5. 如果你不需要它
  6. Pressed_Pleasure
  7. 在地上

一些字符在数字或特殊字符之后得到大写。

我如何限制特殊字符之后的字符不是大写，但是如果单词的第一个字符是特殊字符，那么第二个字符应该是大写作为第二个数字。

尝试2：

我的其他代码给出了一些更好的结果，但它没有大写特殊字符后单词的第二个字符。带输出的代码是

Sub Propername()
rownum = 2
colnum = 1

ActiveSheet.Range("a2", ActiveSheet.Range("a2").End(xlDown)).Select

For Each Cell In Selection

 Text = Trim(StrConv(Cells(rownum, colnum).value, vbProperCase))
 Cells(rownum, colnum + 1) = Text
rownum = rownum + 1
Next
 End Sub

结果

  1. Dtest Dk;k3kj
  2. _dsc0148a
  3. 1陶器2
  4. Articiart147
  5. 如果你不需要它
  6. Pressed_pleasure
  7. 在地上

在第二个和第三个字符中，第二个字符不是大写，而在 6 p 中，快乐也不是大写。

这个/满足你的要求

更新：我添加了修复以解决正确大小写函数和撇号的限制

Sub NotScared_butConfused()
Dim objRegex As Object
Dim objRegMC As Object
Dim objRegM As Object
Dim X
Dim lngCnt As Long

X = Range([a2], Cells(Rows.Count, "A").End(xlUp))
Set objRegex = CreateObject("vbscript.regexp")
With objRegex
.Pattern = "([\_\-\$;:\s])+([a-z])"
.Global = True
For lngCnt = 1 To UBound(X)
X(lngCnt, 1) = Application.Proper(LCase$(X(lngCnt, 1)))
If .test(X(lngCnt, 1)) Then
Set objRegMC = .Execute(X(lngCnt, 1))
For Each regm In objRegMC
Mid$(X(lngCnt, 1), regm.firstindex + 2, 1) = UCase$(regm.submatches(1))
Next
End If
With Application
X(lngCnt, 1) = .Substitute(.Proper(.Substitute(X(lngCnt, 1), "'", "zyx")), "zyx", "'")
End With
Next
End With
If lngCnt > 1 Then [b2].Resize(UBound(X), 1) = X
End Sub

我不知道人们为什么害怕或无法理解这个问题。

excel的正确命令存在编程问题，因为它没有正确更改字符串的大小写，例如在excel的单元格中写入此命令

=proper("If you don't Need It")

您将看到不带引号的结果

"If You Don'T Need It"

对于这种输出，人们永远不会害怕。

我已经编写了以下代码。

Sub Propername()
rownum = 2
colnum = 1

ActiveSheet.Range("a2", ActiveSheet.Range("a2").End(xlDown)).Select

For Each Cell In Selection
   FullName = Cells(rownum, colnum).value
'capitalize the first letter after _. 
   For i = 1 To Len(FullName)
     pos = InStr(1, FullName, "_", vbTextCompare)

    If pos > 1 Then
     text1 = Trim(StrConv(Mid(FullName, 1, pos), vbProperCase))
     text2 = Trim(StrConv(Mid(FullName, pos + 1, 999), vbProperCase))
     Cells(rownum, colnum + 1) = text1 & text2
     cont = 1
    If InStr(1, text2, "_") Then
     pos1 = InStr(1, text2, "_")
     text3 = Trim(StrConv(Mid(text2, 1, pos1), vbProperCase))
     text4 = Trim(StrConv(Mid(text2, pos1 + 1, 999), vbProperCase))
     Cells(rownum, colnum + 1) = text1 & text3 & text4
    End If
   End If
 If pos = 0 Or InStr(1, text2, "_") = False Then cont = 0: Exit For Next
 'capitalize the second letter as capital if first letter is a digit or some special character in string
 Select Case Left(Cells(rownum, colnum).value, 1)
   Case "_", "#", "$", "-", "'", ";", ":"
      Text0 = Mid(FullName, 1, 1)
      text1 = StrConv(Mid(FullName, 2, 1), vbProperCase)
      text2 = Trim(StrConv(Mid(FullName, 3, 999), vbLowerCase))
      Cells(rownum, colnum + 1) = Text0 & text1 & text2
   Case 0 To 9
      Text0 = Mid(FullName, 1, 1)
      text1 = StrConv(Mid(FullName, 2, 1), vbProperCase)
      text2 = Trim(StrConv(Mid(FullName, 3, 999), vbLowerCase))
      Cells(rownum, colnum + 1) = Text0 & text1 & text2

 Case Else
    If cont <> 0 Then
     Text = Trim(StrConv(FullName, vbProperCase))
     Cells(rownum, colnum + 1) = Text
   End If
 End Select

rownum = rownum + 1
Next
 End Sub

我可以改进，特别是如果可以检测到字符串中特殊字符的位置。
