    U can Use Replace function

    ActiveSheet.Cells(1, 1).Value = Replace(ActiveSheet.Cells(1, 1).Value, "String", "Number")

    Following up on the suggestion to use regular expressions, here's an example:

    Option Explicit
    
    Sub RemoveByRegexWithLateBinding()
    
        Dim strIn As String
        Dim strOut As String
        Dim objRegex As Object
    
        'input
        strIn = "This is a <""string"">string, It should be <""changed"">changed to <""a""> a number."
        Debug.Print "Input:" & vbCr & strIn
    
        'create and apply regex
        Set objRegex = CreateObject("VBScript.RegExp")
        objRegex.Pattern = "<""[^<>""]*"">"
        objRegex.Global = True
        strOut = objRegex.Replace(strIn, "")
    
        'test output
        Debug.Print "Output:" & vbCr & strOut
    
    End Sub
    

    Produces this output:

    Input:
    This is a <"string">string, It should be <"changed">changed to <"a"> a number.
    Output:
    This is a string, It should be changed to  a number.
    

    Diagram of regular expression:

    Which can be explained as finding a string that:

    • begins with <"
    • contains anything apart from the characters <, > and "
    • ends with ">

    Assuming the text in cell A1, then try this code

    Sub DelDoubleString()
    Dim Text As String, Text2Replace As String, NewText As String
    On Error Resume Next        'Optional, in case there's no double string to be deleted
    Text = Cells(1, 1)
    
    Do
        Text2Replace = Mid$(Text, InStr(Text, "<"), InStr(Text, ">") - InStr(Text, "<") + 1)
        NewText = Application.WorksheetFunction.Substitute(Text, Text2Replace, vbNullString)
        Text = NewText
    Loop Until InStr(NewText, "<") = 0
    
    Cells(1, 1) = NewText
    
    End Sub

    Select the cells containing your text and run this short macro:

    Sub Kleanup()
        Dim d As Range, s As String, rng As Range
        Dim gather As Boolean, L As Long, DQ As String
        Dim i As Long, s2 As String, CH As String
    
        Set rng = Selection
        DQ = Chr(34)
    
        For Each r In rng
            s = Replace(r.Text, "<" & DQ, Chr(1))
            s = Replace(s, DQ & ">", Chr(2))
            gather = True
            L = Len(s)
            s2 = ""
            For i = 1 To L
                CH = Mid(s, i, 1)
                If CH = Chr(1) Then gather = False
                If CH = Chr(2) Then gather = True
                If gather And CH <> Chr(2) Then s2 = s2 & CH
            Next i
            r.Value = s2
        Next r
    End Sub
