有沒有一種簡單的方法可以替換為Excel中的占位符？

Question

我有一個這樣的公式：

=IF(OR($A1="xyz",$B1="abc",$C5="dmz"),1,0)

我想將每個單元格地址替換為一個明確指出工作表的靜態地址，即

=IF(OR(Sheet1!$A$1="xyz",Sheet1!$B$1="abc",Sheet1!$C$5="dmz"),1,0)

我有這個：

Public Function absoluteFormula(sheetname As String, ByVal formula As String) As String

Dim re As New RegExp
Dim matches As MatchCollection
Dim mtch As Match
Dim absoluteAddress As String


'get all addresses in formula
re.pattern = "[$][A-Za-z]+[0-9]+"
re.Global = True

Set matches = re.Execute(formula)

'replace each address with its static version
For Each mtch In matches
    absoluteAddress = sheetname & "!" & getAbsoluteAddress(re, mtch.value)
    formula = Replace(formula, mtch.value, absoluteAddress)
Next

absoluteFormula = formula

End Function


'makes row static, e.g. "$AU1" -> "$AU$1"
Private Function getAbsoluteAddress(re As RegExp, address As String)

Dim matches As MatchCollection
Dim alphaColumn As String


re.pattern = "[A-Za-z]+"

Set matches = re.Execute(address)
alphaColumn = matches(0).value
getAbsoluteAddress = Replace(address, alphaColumn, alphaColumn & "$")


End Function

這似乎需要很多代碼來完成基本的（偽代碼）：

find all instances of "[$][alpha]+"
replace with sheetname & "!" & instance & "$"

有沒有更簡單的方法來執行此替換？

沒有經過完全測試，但是這樣會有所幫助嗎？ 選擇具有公式的單個單元格，然后運行Sample 。 我沒有做任何錯誤處理。 我假設ActiveCell 將有一個公式。 我也同意您在上述評論中所說的，您的公式將沒有命名范圍

Dim sformula As String
Dim sh As String

Sub Sample()
    Dim cell As Range, c As Range

    '~~> This is what you want to append
    sh = "Sheet1!"

    '~~> Store the formula in a variable
    sformula = ActiveCell.Formula

    Debug.Print sformula

    '~~> Get the precedents
    Set cell = ActiveCell.Precedents

    '~~> Loop though them
    For Each c In cell
        ReplaceAddress c.Address                                            '~~> $A$1
        ReplaceAddress c.Address(RowAbsolute:=False)                        '~~> $A1
        ReplaceAddress c.Address(ColumnAbsolute:=False)                     '~~> A$1
        ReplaceAddress c.Address(RowAbsolute:=False, ColumnAbsolute:=False) '~~> A1
    Next

    Debug.Print sformula
End Sub

Function ReplaceAddress(s As String) As String
    Dim pos As Long

    pos = InStr(1, sformula, s)

    Do While pos > 0
        If pos = 1 Then
            sformula = sh & sformula
        ElseIf pos > 1 Then
            '~~> Various checks for "!","$" and ":"
            If Mid(sformula, pos - 1, 1) <> "!" And Mid(sformula, pos - 1, 1) <> "$" And _
            Mid(sformula, pos - 1, 1) <> ":" And Mid(sformula, pos - 2, 1) <> ":" Then
                sformula = Left(sformula, pos - 1) & sh & Mid(sformula, pos)
            End If
        End If
        '~~> Find next occurance
        pos = InStr(pos + 1, sformula, s)
    Loop
    ReplaceAddress = sformula
End Function

各種測試

之前：

=IF(OR($A1="xyz",$B1="abc",$C5="dmz"),1,0)

后：

=IF(OR(Sheet1!$A1="xyz",Sheet1!$B1="abc",Sheet1!$C5="dmz"),1,0)

---

之前：

=VLOOKUP(K4,N10:Q18,1,0)

后：

=VLOOKUP(Sheet1!K4,Sheet1!N10:Q18,1,0)

---

稍微復雜一點的測試

之前：

=IF(G4>MAX($D$4:$D$8),"N/A",INDEX($B$4:$B$8,INDEX(MATCH(G4,$C$4:$C$8,1),0,0),0))

后：

=IF(Sheet1!G4>MAX(Sheet1!$D$4:$D$8),"N/A",INDEX(Sheet1!$B$4:$B$8,INDEX(MATCH(Sheet1!G4,Sheet1!$C$4:$C$8,1),0,0),0))

評論的跟進

用這個

Sub Sample()
    Dim cell As Range, c As Range

    '~~> This is what you want to append
    sh = "Sheet1!"

    '~~> Store the formula in a variable
    sformula = ActiveCell.Formula

    Debug.Print sformula

    '~~> Get the precedents
    Set cell = ActiveCell.Precedents

    '~~> Loop though them
    For Each c In cell
        ReplaceAddress c.Address                                            '~~> $A$1
        ReplaceAddress c.Address(RowAbsolute:=False)                        '~~> $A1
        ReplaceAddress c.Address(ColumnAbsolute:=False)                     '~~> A$1
        ReplaceAddress c.Address(RowAbsolute:=False, ColumnAbsolute:=False) '~~> A1

        sformula = Replace(sformula, c.Address(RowAbsolute:=False), c.Address)
        sformula = Replace(sformula, c.Address(ColumnAbsolute:=False), c.Address)
        sformula = Replace(sformula, c.Address(RowAbsolute:=False, ColumnAbsolute:=False), c.Address)
    Next

    Do While InStr(1, sformula, "$$")
        sformula = Replace(sformula, "$$", "$")
    Loop

    Debug.Print sformula
End Sub

Function ReplaceAddress(s As String) As String
    Dim pos As Long

    pos = InStr(1, sformula, s)

    Do While pos > 0
        If pos = 1 Then
            sformula = sh & sformula
        ElseIf pos > 1 Then
            '~~> Various checks for "!","$" and ":"
            On Error Resume Next
            If Mid(sformula, pos - 1, 1) <> "!" And Mid(sformula, pos - 1, 1) <> "$" And _
            Mid(sformula, pos - 1, 1) <> ":" And Mid(sformula, pos - 2, 1) <> ":" Then
                sformula = Left(sformula, pos - 1) & sh & Mid(sformula, pos)
            End If
            On Error GoTo 0
        End If
        '~~> Find next occurance
        pos = InStr(pos + 1, sformula, s)
    Loop
    ReplaceAddress = sformula
End Function
