如何在 Excel 中将文本字符串转换为正确的大小写并包含例外情况？

您是否曾经想过在 Excel 中是否有方法可以自动更正句子中字符串的大小写？在 Excel 中可以实现这一点。本教程将帮助您了解如何在 Excel 中将文本字符串转换为正确的大小写并包含例外情况。我们可以使用 VBA 应用程序来完成此任务，因为它无法直接在 Excel 中完成。当单词的字母根据语法以正确的大小写显示时，它们被称为“正确的大小写”。

在 Excel 中将文本字符串转换为正确的大小写并包含例外情况

在这里，我们将首先创建例外情况列表，然后插入 VBA 模块并运行它以完成任务。让我们看一下在 Excel 中将字符串转换为正确的大小写并包含例外情况的简单过程。

步骤 1

让我们考虑一个 Excel 工作表，其中数据工作表类似于下图所示的数据。

然后右键单击工作表名称并选择“查看代码”以打开 VBA 应用程序。然后单击“插入”并选择“模块”。

右键单击 > 查看代码 > 插入 > 模块

步骤 2

在文本框中键入以下程序代码，如下图所示。

程序

Sub CellsValueChange()

    Dim xDRg As Range
    Dim xPRg As Range
    Dim xSRgArea As Range
    Dim xRgVal As String
    Dim xAddress As String
    Dim I As Long
    Dim K As Long
    Dim KK As Long
    On Error Resume Next
    xAddress = Application.ActiveWindow.RangeSelection.Address
    Set xSRg = Application.InputBox("Original cells:", "Proper Text String", xAddress, , , , , 8)
    If xSRg Is Nothing Then Exit Sub
    Set xDRg = Application.InputBox("Output cells:", "Proper Text String", , , , , , 8)
    If xDRg Is Nothing Then Exit Sub
    Set xPRg = Application.InputBox("Cells to exclude:", "Proper Text String", , , , , , 8)
    If xPRg Is Nothing Then Exit Sub
    Set xDRg = xDRg(1)
    For I = 1 To xSRg.Areas.Count
        Set xSRgArea = xSRg.Areas.Item(I)
        For K = 1 To xSRgArea.Count
            xRgVal = xSRgArea(K).Value
            If Not IsNumeric(xRgVal) Then
                xRgVal = CorrectCase(xRgVal, xPRg)
                xDRg.Offset(KK).Value = xRgVal
            End If
            KK = KK + 1
        Next
    Next
End Sub

        Debug.Print xPointer
        Mid(xVal, xPointer) = CorrectCaseOneWord(CStr(xArrWords(I)), xPRg)
    Next I
    CorrectCase = xVal
End Function
Function WordsOf(xRgVal As String) As Variant
    Dim xDelimiters As Variant
    Dim xArrRtn As Variant
    xDelimiters = Array(",", ".", ";", ":", Chr(34), vbCr, vbLf)
    For Each xEachDelimiter In xDelimiters
        xRgVal = Application.WorksheetFunction.Substitute(xRgVal, xEachDelimiter, " ")
    Next xEachDelimiter
    xArrRtn = Split(Trim(xRgVal), " ")
    WordsOf = xArrRtn
End Function
Function CorrectCaseOneWord(xArrWord As String, xERg As Range) As String
    With xERg
        If IsError(Application.Match(xArrWord, .Cells, 0)) Then
            CorrectCaseOneWord = Application.Proper(xArrWord)
        Else
            CorrectCaseOneWord = Application.VLookup(xArrWord, .Cells, 1, 0)
        End If
    End With
End Function
