[發問] 2儲存格中字串差異顯示

free72921

由於工作上偶爾會需要比對2儲存格中的字串差異，
字串數量龐大時非常傷眼，請問各位前輩是否有較
好的方式比對2儲存格中字串的差異並顯示出來。
感謝各位前輩

請測試看看，謝謝

For j = 0 To UBound(Split(xR, ","))
    T = Split(xR, ",")(j): xD(T) = 1
Next
xR1 = Range("c3")
For j = 0 To UBound(Split(xR1, ","))
    T = Split(xR1, ",")(j): xD1(T) = 1
Next
For Each ky In xD
If xD1(ky) <> 1 Then: ReDim Preserve Ar(n): Ar(n) = ky: n = n + 1
Next
For Each ky In xD1
If xD(ky) <> 1 Then: ReDim Preserve Ar1(n1): Ar1(n1) = ky: n1 = n1 + 1
Next
If n1 > 0 Then
    For j = 0 To UBound(Ar1)
        T = Ar1(j): L = Len(T): pos = InStr(Range("c3"), T)
        Range("c3").Characters(pos, L).Font.ColorIndex = 3
    Next
End If
If n > 0 Then
    For j = 0 To UBound(Ar)
        T = Ar(j): L = Len(T): pos = InStr(Range("b3"), T)
        Range("b3").Characters(pos, L).Font.ColorIndex = 3

請教各位大大，如果同時有2個以上的差異，後學目前只能將第1個差異反顏色(2#程式碼)，
不知各位大大是否可以將其他的差異也一併反顏色? 感謝
如附圖，第2個R777要反顏色。

感謝各位前輩幫忙，三位前輩的程式都可以比對出差異。
但2樓前輩的程式只會跑出第一個差異，後續再有差異則無法顯示，
另外2位前輩的程式都可以顯示出每一個差異點。

另有一事相求，像這樣的字串差異是否有可能以另一種方式執行，
因為每次比對時會有多個儲存格同時進行。

例如：
跳出詢問視窗【請選擇範圍A】
跳出詢問視窗【請選擇範圍B】
再以被選定的2個範圍開始進行比對
感謝各位前輩

你比較細心，確實有可能2個號碼在前後不同地方

我原先程式修改位置 *1 *2 *3
Sub test()
    ' 清除字顏色及粗體
    With Range("B3:C" & [C65536].End(xlUp).Row).Font
        .ColorIndex = xlAutomatic

    End With
   
    Set xB = [b3]
    Set xC = [c3]
    While xB <> ""
        If xB.Value <> xC.Value Then
            Call NotFindChar(xB, xC)
            Call NotFindChar(xC, xB)
        End If
        Set xB = xB(2, 1)
        Set xC = xC(2, 1)
    Wend
    Debug.Print "time", Time
End Sub

Sub NotFindChar(xC, xS)
    ArrC = Split(xC.Value, ",")
    nStart = 1 '*1
    For i = 0 To UBound(ArrC)
        If InStr("," & xS & ",", "," & ArrC(i) & ",") = 0 Then
            nS = InStr(nStart, "," & xC & ",", "," & ArrC(i) & ",") '*2
            nL = Len(ArrC(i))

我是很粗心的人，只是剛好看到此問題，
另外，看到版主解答，也學習一下而想到解法，感謝。
