Question

以下是Excel中设置的示例

[column1] [column2]

A1  =C3-C5

A2  =((C4-C6)/C6)

A3  =C4*C3

A4  =C6/C7

A5  =C6*C4*C3

我需要在公式中提取使用过的引用

例如，

for "A1", I simply need to get the C3 and C5.
for A2, I need to get the C4 and C6.

这是对以下内容的更新：

适用于本地工作表参考，但不适用于表外参考。 - brettdj 5月14日和14日11:55

通过使用Larrys方法，只需将objRegEx.Pattern更改为：

(['].*?['!])?([[A-Z0-9_]+[!])?(\$?[A-Z]+\$?(\d)+(:\$?[A-Z]+\$?(\d)+)?|\$?[A-Z]+:\$?[A-Z]+|(\$?[A-Z]+\$?(\d)+))

这将：

搜索可选的外部链接：(['].*?['!])?
搜索可选的工作表参考：([[A-Z0-9_]+[!])?
按优先顺序执行以下步骤：
搜索行号（和可选$）的范围：\$?[A-Z]+\$?(\d)+(:\$?[A-Z]+\$?(\d)+)?
搜索没有行号的范围（和可选的$）：\$?[A-Z]+:\$?[A-Z]+
搜索单元格引用（和可选$）：(\$?[A-Z]+\$?(\d)+)

导致：

Sub testing()
Dim result As Object
Dim r As Range
Dim testExpression As String
Dim objRegEx As Object

Set r = Cells(1, 2)  ' INPUT THE CELL HERE , e.g.    RANGE("A1")
Set objRegEx = CreateObject("VBScript.RegExp")
objRegEx.IgnoreCase = True
objRegEx.Global = True
objRegEx.Pattern = """.*?"""  ' remove expressions
testExpression = CStr(r.Formula)
testExpression = objRegEx.Replace(testExpression, "")
objRegEx.Pattern = "(([A-Z])+(\d)+)"  'grab the address

objRegEx.Pattern = "(['].*?['!])?([[A-Z0-9_]+[!])?(\$?[A-Z]+\$?(\d)+(:\$?[A-Z]+\$?(\d)+)?|\$?[A-Z]+:\$?[A-Z]+|(\$?[A-Z]+\$?(\d)+))"
If objRegEx.test(testExpression) Then
    Set result = objRegEx.Execute(testExpression)
    If result.Count > 0 Then
        For Each Match In result
            Debug.Print Match.Value
        Next Match
    End If
End If
End Sub

这样做，会给你所有可能参考的价值，我能想到的。（更新了这篇文章，因为我需要解决问题）。

Answer 2

此函数返回逗号分隔的源单元格列表（先例）：

Function References(rngSource As Range) As Variant
    Dim rngRef As Range
    Dim strTemp As String
    On Error Resume Next
    For Each rngRef In rngSource.Precedents.Cells
        strTemp = strTemp & ", " & rngRef.Address(False, False)
    Next
    If Len(strTemp)  0 Then strTemp = Mid(strTemp, 3)
    References = strTemp
End Function

但是，请注意，您不能在工作表中将其用作UDF，因为rngRef.Address不幸导致循环引用。但是，您可以在一个小程序中使用它来填充另一列，例如

Sub ShowPrecedents()
    Dim rng As Range
    'Will paste precedents of A1:A6 into D1:D6
    For Each rng In Range("D1:D6")
        rng.Value = References(rng.Offset(, -3))
    Next
End Sub

Answer 3

只是为您提供另一种选择...请注意，如果多次调用单元格，则会返回重复结果

Sub testing()
Dim result As Object
Dim r As Range
Dim testExpression As String
Dim objRegEx As Object

Set r = Cells(1, 2)  ' INPUT THE CELL HERE , e.g.    cells("A1")
Set objRegEx = CreateObject("VBScript.RegExp")
objRegEx.IgnoreCase = True
objRegEx.Global = True
objRegEx.Pattern = """.*"""  ' remove expressions
testExpression = CStr(r.Formula)
testExpression = objRegEx.Replace(testExpression, "")
objRegEx.Pattern = "(([A-Z])+(\d)+)"  'grab the address

If objRegEx.test(testExpression) Then
    Set result = objRegEx.Execute(testExpression)
    If result.Count > 0 Then
        For Each Match In result
            Debug.Print Match.Value
        Next Match
    End If
End If
End Sub

结果存储在“Match.Value”

中
