访问VBA解析json

Question

有人可以帮助使用 Access VBA 代码来解析以下 json 文本吗？我需要检索作者、标题、评论、original_title、original_review、stars、iso、版本、日期、产品、重量和 id 的值，然后循环到下一个条目和下一个条目。

{
"total": 140,
"pages": 28,
"this_page": 1,
"reviews": [{
    "author": "DeveloperToDeveloper",
    "title": "Just Spectacular",

    "original_review": null,
    "stars": "5.00",
    "iso": "US",
    "version": "1.2",

Sub ParseJson()

    Dim j As String, sc As Object, num As Long, i

    j = Range("A1").Value 'I'm testing in excel...

    Set sc = CreateObject("ScriptControl")
    sc.Language = "JScript"

    'evaluate the json to create a "response" object
    sc.ExecuteStatement "var response = eval((" & j & "));"

    'create a function to return us a piece of data
    '   based on the passed-in js fragment
    sc.ExecuteStatement "var f = function(s){return eval(s);};"

    'how many reviews ?
    num = sc.Eval("f('response.reviews.length')") '>> 4

    For i = 0 To num - 1
        Debug.Print "------- Review " & i & "---------------"
        Debug.Print sc.Eval("f('response.reviews[" & i & "].author')")
        Debug.Print sc.Eval("f('response.reviews[" & i & "].title')")
        'etc etc
    Next i

End Sub
