Excel VBA에서 JSON 구문 분석


Excel VBA : Parsed JSON Object Loop 와 동일한 문제가 있지만 솔루션을 찾을 수 없습니다. 내 JSON에는 중첩 개체가 있으므로 VBJSON 및 vba-json과 같은 제안 된 솔루션이 작동하지 않습니다. 나는 또한 그들 중 하나가 제대로 작동하도록 수정했지만 결과는 doProcess 함수의 많은 재귀로 인해 호출 스택 오버플로였습니다.

가장 좋은 해결책은 원본 게시물에서 볼 수있는 jsonDecode 함수로 보입니다. 매우 빠르고 효과적입니다. 내 개체 구조는 JScriptTypeInfo 형식의 일반 VBA 개체에 모두 있습니다.

이 시점에서 문제는 객체의 구조를 결정할 수 없기 때문에 각 일반 객체에 상주 할 키를 미리 알지 못한다는 것입니다. 키 / 속성을 얻기 위해 일반 VBA 개체를 반복해야합니다.

내 구문 분석 자바 스크립트 함수가 VBA 함수 또는 하위를 트리거 할 수 있다면 훌륭 할 것입니다.


을 기반으로 빌드 ScriptControl하려면 몇 가지 도우미 메서드를 추가하여 필요한 정보를 얻을 수 있습니다. JScriptTypeInfo개체는 약간 안타깝습니다. 모든 관련 정보가 포함되어 있지만 ( 감시에서 볼 수 있음 ) VBA로는 얻을 수 없습니다. 그러나 Javascript 엔진은 다음과 같은 도움을 줄 수 있습니다.

Option Explicit

Private ScriptEngine As ScriptControl

Public Sub InitScriptEngine()
    Set ScriptEngine = New ScriptControl
    ScriptEngine.Language = "JScript"
    ScriptEngine.AddCode "function getProperty(jsonObj, propertyName) { return jsonObj[propertyName]; } "
    ScriptEngine.AddCode "function getKeys(jsonObj) { var keys = new Array(); for (var i in jsonObj) { keys.push(i); } return keys; } "
End Sub

Public Function DecodeJsonString(ByVal JsonString As String)
    Set DecodeJsonString = ScriptEngine.Eval("(" + JsonString + ")")
End Function

Public Function GetProperty(ByVal JsonObject As Object, ByVal propertyName As String) As Variant
    GetProperty = ScriptEngine.Run("getProperty", JsonObject, propertyName)
End Function

Public Function GetObjectProperty(ByVal JsonObject As Object, ByVal propertyName As String) As Object
    Set GetObjectProperty = ScriptEngine.Run("getProperty", JsonObject, propertyName)
End Function

Public Function GetKeys(ByVal JsonObject As Object) As String()
    Dim Length As Integer
    Dim KeysArray() As String
    Dim KeysObject As Object
    Dim Index As Integer
    Dim Key As Variant

    Set KeysObject = ScriptEngine.Run("getKeys", JsonObject)
    Length = GetProperty(KeysObject, "length")
    ReDim KeysArray(Length - 1)
    Index = 0
    For Each Key In KeysObject
        KeysArray(Index) = Key
        Index = Index + 1
    Next
    GetKeys = KeysArray
End Function


Public Sub TestJsonAccess()
    Dim JsonString As String
    Dim JsonObject As Object
    Dim Keys() As String
    Dim Value As Variant
    Dim j As Variant

    InitScriptEngine

    JsonString = "{""key1"": ""val1"", ""key2"": { ""key3"": ""val3"" } }"
    Set JsonObject = DecodeJsonString(CStr(JsonString))
    Keys = GetKeys(JsonObject)

    Value = GetProperty(JsonObject, "key1")
    Set Value = GetObjectProperty(JsonObject, "key2")
End Sub

몇 가지 참고 :

  • 경우 JScriptTypeInfo인스턴스가 자바 스크립트 객체를 참조, For Each ... Next작동하지 않습니다. 그러나 Javascript 배열을 참조하면 작동합니다 ( GetKeys함수 참조 ).
  • 이름이 런타임에만 알려진 액세스 속성은 GetProperty함수를 사용합니다 GetObjectProperty.
  • 자바 스크립트 배열이 속성 제공 length, 0, Item 0, 1, Item 1VBA를 점 표기법 (로 등 jsonObject.property), 단지 길이 속성을 사용하면라는 변수 선언 할 경우에만 액세스 할 수 있으며 length모든 소문자 문자로합니다. 그렇지 않으면 케이스가 일치하지 않고 찾을 수 없습니다. 다른 속성은 VBA에서 유효하지 않습니다. 따라서 GetProperty기능을 더 잘 사용하십시오 .
  • 코드는 초기 바인딩을 사용합니다. 따라서 "Microsoft Script Control 1.0"에 대한 참조를 추가해야합니다.
  • InitScriptEngine기본 초기화를 수행하려면 다른 함수를 사용하기 전에 한 번 호출해야합니다 .

• 그래도 참고 ScriptControl가 액티브 X의를 통해 악성 JS 코드에 대한 드라이브 (및 기타 물건)에 직접 액세스 할 수 있기 때문에 기반 approachs은, 어떤 경우에는 취약한 시스템을 만든다. .NET과 같은 웹 서버 응답 JSON을 구문 분석한다고 가정 해 보겠습니다 JsonString = "{a:(function(){(new ActiveXObject('Scripting.FileSystemObject')).CreateTextFile('C:\\Test.txt')})()}". 평가 후 새로 생성 된 파일을 찾을 수 있습니다 C:\Test.txt. 따라서 ScriptControlActiveX를 사용한 JSON 구문 분석 은 좋은 생각이 아닙니다.

이를 피하기 위해 RegEx를 기반으로 JSON 파서를 만들었습니다. 객체는 {}사전의 속성과 메서드를 사용할 수있게하는, 사전으로 표현된다 : .Count, .Exists(), .Item(), .Items, .Keys. 배열 []은 기존의 0 기반 VB 배열이므로 UBound()요소 수를 표시합니다. 다음은 몇 가지 사용 예가있는 코드입니다.

VB 코드에서 array.myitem (0)으로 이동할 수있는 더 간단한 방법

여기 내 전체 답변은 구문 분석 및 문자열 화 (직렬화)

js에서 'this'객체 사용

ScriptEngine.AddCode "Object.prototype.myitem=function( i ) { return this[i] } ; "

그런 다음 array.myitem (0) 갈 수 있습니다.

Private ScriptEngine As ScriptControl

Public Sub InitScriptEngine()
    Set ScriptEngine = New ScriptControl
    ScriptEngine.Language = "JScript"
    ScriptEngine.AddCode "Object.prototype.myitem=function( i ) { return this[i] } ; "
    Set foo = ScriptEngine.Eval("(" + "[ 1234, 2345 ]" + ")") ' JSON array
    Debug.Print foo.myitem(1) ' method case sensitive!
    Set foo = ScriptEngine.Eval("(" + "{ ""key1"":23 , ""key2"":2345 }" + ")") ' JSON key value
    Debug.Print foo.myitem("key1") ' WTF

End Sub

Json은 문자열 일 뿐이므로 구조가 아무리 복잡하더라도 올바른 방식으로 조작 할 수 있다면 쉽게 처리 할 수 ​​있습니다. 트릭을 수행하기 위해 외부 라이브러리 또는 변환기를 사용할 필요가 없다고 생각합니다. 다음은 문자열 조작을 사용하여 json 데이터를 구문 분석 한 예입니다.

Sub FetchData()
    Dim str As Variant, N&, R&

    With New XMLHTTP60
        .Open "GET", "https://oresapp.asicanada.net/ores.imis.services/api/member/?address=&callback=angular.callbacks._0&city=&companyName=&personName=", False
        .send
        str = Split(.responseText, ":[{""Id"":")
    End With

    N = UBound(str)

    For R = 1 To N
        Cells(R, 1) = Split(Split(str(R), "FullName"":""")(1), """")(0)
        Cells(R, 2) = Split(Split(str(R), "Phone"":""")(1), """")(0)
        Cells(R, 3) = Split(Split(str(R), "Email"":""")(1), """")(0)
    Next R
End Sub

이것은 Excel 및 네이티브 형식으로 번역 된 JSON 쿼리를 사용하는 큰 JSON 파일에서 저에게 적합합니다. https://github.com/VBA-tools/VBA-JSON "item.something"과 같은 노드를 구문 분석하고 간단한 명령을 사용하여 값을 가져올 수 있습니다.

MsgBox Json("item")("something")

좋은게 뭐야.


코도 감사합니다.

방금 업데이트하고 완료 한 작업 :

  • json 직렬화 (텍스트와 같은 문서에 json을 삽입하는 데 필요함)
  • 노드 추가, 제거 및 업데이트 (누가 아는가)

' "recursive" version of GetObjectProperty
Public Function GetObjectProperty(ByVal JsonObject As Object, ByVal propertyName As String) As Object
    Dim names() As String
    Dim i As Integer

    names = Split(propertyName, ".")

    For i = 0 To UBound(names)
        Set JsonObject = ScriptEngine.Run("getProperty", JsonObject, names(i))
    Next

    Set GetObjectProperty = JsonObject

' shortcut to object array

    Dim l As Integer

    Set JsonObject = GetObjectProperty(JsonObject, propertyName)

    l = GetProperty(JsonObject, "length") - 1

    For i = 0 To l

이제 다음과 같은 작업을 수행 할 수 있습니다.

Dim JsonObject As Object
Dim Value() As Object
Dim i As Integer
Dim Total As Double

Set JsonObject = DecodeJsonString(CStr(request.responseText))

Value = GetObjectArrayProperty(JsonObject, "d.Data")

For i = 0 To UBound(Value)
    Total = Total + Value(i).Amount
Next
