This function extracts the cell references from a string and returns them in another cell.
Example: D10 contains =A4+B23+100-SUM(K12:L15)
G10 contains =ExtractCellRefs(D10) and that returns A4, B23, K12:L15

Is it possible to convert this to a macro, where every cell in column D with a value has its cell references (or "No Matches") returned on the same row in column G?

Code:
Function ExtractCellRefs(Rg As Range) As String
    Dim xRetList As Object
    Dim xRegEx As Object
    Dim I As Long
    Dim xRet As String

    Application.Volatile
    Set xRegEx = CreateObject("VBSCRIPT.REGEXP")
    With xRegEx
        .Pattern = "('?[a-zA-Z0-9\s\[\]\.]{1,99})?'?!?\$?[A-Z]{1,3}\$?[0-9]{1,7}(:\$?[A-Z]{1,3}\$?[0-9]{1,7})?"
        .Global = True
        .MultiLine = True
        .IgnoreCase = False
    End With
    Set xRetList = xRegEx.Execute(Rg.Formula)
    If xRetList.Count > 0 Then
        For I = 0 To xRetList.Count - 1
            xRet = xRet & xRetList.Item(I) & ", "
        Next
        ExtractCellRefs = Left(xRet, Len(xRet) - 2)
    Else
        ExtractCellRefs = "No Matches"
    End If
End Function

Wildcard in VLOOKUP
Use =VLOOKUP("Apple*" to find apple, Apple, or applesauce

Try this.
VBA Code:
Sub ExtractCellRefs()
    Dim xRetList As Object
    Dim xRegEx As Object
    Dim I As Long
    Dim xRet As String

    Application.ScreenUpdating = False
    Set xRegEx = CreateObject("VBSCRIPT.REGEXP")
    With xRegEx
        .Pattern = "('?[a-zA-Z0-9\s\[\]\.]{1,99})?'?!?\$?[A-Z]{1,3}\$?[0-9]{1,7}(:\$?[A-Z]{1,3}\$?[0-9]{1,7})?"
        .Global = True
        .MultiLine = True
        .IgnoreCase = False
    End With
       
   For Each Rg In Range("D3:D" & Range("D" & Rows.Count).End(xlUp).row)
       
    Set xRetList = xRegEx.Execute(Rg.Formula)
    If xRetList.Count > 0 Then
        For I = 0 To xRetList.Count - 1
            xRet = xRet & xRetList.Item(I) & ", "
        Next
        Rg.Offset(0, 3) = Left(xRet, Len(xRet) - 2)
    Else
        Rg.Offset(0, 3) = "No Matches"
    End If
    xRet = ""
    Next Rg
    
   Application.ScreenUpdating = True
End Sub

Hope that helps
