Excel 替换单元格中的单词,excel,vba,Excel,Vba,我正在尝试创建一个简单的翻译脚本，它将从一个范围（列）查看每个单元格中的一个句子，并根据我创建的简单的两列（lookat/replace）翻译内存逐字翻译如果单元格包含 "This app is cool" 翻译记忆是 This | 1 app | 2 cool | 3 结果应该是： "1 2 is 3" 但是，使用.Replace方法，以下字符串： "This apple from the cooler" 会回来吗 "1 2le from the 3er" 我使用数组和拆分方法将

我正在尝试创建一个简单的翻译脚本，它将从一个范围（列）查看每个单元格中的一个句子，并根据我创建的简单的两列（lookat/replace）翻译内存逐字翻译

如果单元格包含

"This app is cool"

翻译记忆是

This | 1
app  | 2
cool | 3

结果应该是：

"1 2 is 3"

但是，使用

.Replace

方法，以下字符串：

"This apple from the cooler"

会回来吗

"1 2le from the 3er"

我使用数组和拆分方法将句子拆分成单词，然后从翻译列表中查找每个单词，以进行

xlother

匹配。我有大约10000行句子，将每个句子分解成大约100000个单词，每个单词浏览大约1000个翻译单词。这是一句话。。但是有点慢

有没有其他更好的方法？

Word拯救：这里我使用Word的查找/替换功能中的“仅匹配整个单词”选项

Dim rngSentences As Range
Dim sentences, translatedSentences, wordsToReplace, newStrings 
Dim iWord As Long
Dim iSentence As Long
Dim cell As Range
Dim w As Word.Application
Dim d As Word.Document

Set rngSentences = Range("A1:A5")
wordsToReplace = Array("this", "app", "cool")
newStrings = Array("1", "2", "3")

Set w = New Word.Application
Set d = w.Documents.Add(DocumentType:=wdNewBlankDocument)
sentences = rngSentences.Value ' read sentences from sheet
ReDim translatedSentences(LBound(sentences, 1) To UBound(sentences, 1), _
    LBound(sentences, 2) To UBound(sentences, 2))

For iSentence = LBound(sentences, 1) To UBound(sentences, 1)
    'Put sentence in Word document
    d.Range.Text = sentences(iSentence, 1)
    'Replace the words
    For iWord = LBound(wordsToReplace) To UBound(wordsToReplace)
        d.Range.Find.Execute Findtext:=wordsToReplace(iWord), _
            Replacewith:=newStrings(iWord), MatchWholeWord:=True
    Next iWord
    'Grab sentence back from Word doc
    translatedSentences(iSentence, 1) = d.Range.Text
Next iSentence
'slap translated sentences onto sheet
rngSentences.Offset(0, 1) = translatedSentences

w.Quit savechanges:=False

另一种可能更快的方法是，将所有句子一次粘贴到Word文档中，替换所有内容，然后将所有内容复制粘贴回Excel工作表。它可能更快；我不知道，我还没有对它进行广泛的测试；这取决于你自己

要实现这一点，可以将

Set d=…

后面的行替换为：

'Copy-paste all sentences into Word doc
rngSentences.Copy
d.Range.PasteSpecial DataType:=wdPasteText
'Replace words
For iWord = LBound(wordsToReplace) To UBound(wordsToReplace)
    d.Range.Find.Execute Findtext:=wordsToReplace(iWord), Replacewith:=newStrings(iWord), _
        MatchWholeWord:=True
Next iWord
'Copy-paste back to Excel sheet
d.Range.Copy
rngSentences.Offset(0, 1).PasteSpecial xlPasteValues
w.Quit savechanges:=False

rngSentences.Offset(0, 1).PasteSpecial xlPasteValues

如果需要，可以使用正则表达式
按照计划：

守则：

' reference: "Microsoft VBScript Regular Expressions 5.5" Dim RegX As Object, Mats As Object, Counter As Long Set RegX = CreateObject("VBScript.RegExp") Dim TrA(1 To 1000) As String Dim TrB(1 To 1000) As String Dim TrMax As Integer Dim StrSp For i = 1 To 9999 If Range("D" & i).Value = "" Then Exit For TrA(i) = Range("D" & i).Value TrB(i) = Range("E" & i).Value TrMax = i Next Range("B1:B10").ClearContents For i = 1 To 9999 If Range("A" & i).Value = "" Then Exit For With RegX .Global = True .Pattern = "[a-zA-Z0-9]+" Set Mats = .Execute(Range("A" & i).Value) End With kk = Range("A" & i).Value For Counter = 0 To Mats.Count - 1 For e = 1 To TrMax If LCase(Mats(Counter)) = TrA(e) Then kk = Replace(kk, Mats(Counter), TrB(e), , 1) End If Next Next Range("B" & i).Value = kk Next Set Mats = Nothing Set RegX = Nothing

Regex很快，但是单词代码非常有趣（复制和粘贴…：-）

这里是另一个使用替换方法和单词边界的Regex解决方案（Regex模式中的“\b”表示单词边界）。它假定您的源位于A列，结果将进入B列
翻译表在宏中是硬编码的，但是您可以很容易地将其更改为从工作簿中的表中提取

Option Explicit Sub Translate() Dim V As Variant Dim RE As Object Dim arrTranslate As Variant Dim I As Long, J As Long Dim S As String V = Range("a1", Cells(Rows.Count, "A").End(xlUp)) ReDim Preserve V(1 To UBound(V, 1), 1 To 2) arrTranslate = VBA.Array(Array("This", 1), Array("app", 2), Array("cool", 3)) Set RE = CreateObject("vbscript.regexp") With RE .Global = True .ignorecase = True End With For I = 1 To UBound(V, 1) S = V(I, 1) For J = 0 To UBound(arrTranslate) RE.Pattern = "\b" & arrTranslate(J)(0) & "\b" S = RE.Replace(S, arrTranslate(J)(1)) Next J V(I, 2) = S Next I Range(Cells(1, 1), Cells(UBound(V, 1), UBound(V, 2))) = V End Sub

解决方案。我已经开始使用Regex。。。非常漂亮的东西。@brettdj谢谢你。正则表达式可能比直接的VBA函数慢，但编程起来要简单得多。@RonRosenfeld感谢您的回答。我使用分割数组的方式使其工作，但不会享受更快的方法=]+1高效完成。享受
