如何在vba中的json字符串中提取元素

我有以下json字符串:

[
    {
        "Features": {
            "Level": [
                {
                    "endDate": "2018-12-11",
                    "minimum": "0.000000000000",
                    "maximum": "0.000000000000",
                    "value": "228.108000000000",
                    "payDate": "0"
                },
                {
                    "endDate": "2018-12-11",
                    "minimum": "0.000000000000",
                    "maximum": "0.000000000000",
                    "value": "3143.513000000000",
                    "payDate": "0"
                }
            ]
        }
    },
]

我试图使用vba提取excel中的两个值,并使用以下代码(其中result2为json字符串)

Public Sub GetS (result2 As String, m As Integer)

Dim activeWS As Worksheet
Set activeWS = ThisWorkbook.Worksheets("Data")
Dim jsonStr As String, json As Object, headers()
jsonStr = result2 
Set json = JsonConverter.ParseJson(jsonStr)(1)
activeWS.Cells(m, 19) = json("Features")("Level")(0)("value")
activeWS.Cells(m, 20) = json("Features")("Level")(1)("value")


End Sub

vba的第二部分起作用了,它抓住了3143.51(第二个数字)的值,我想知道如何获得第一个值(228.10)。

我尝试使用(“ Initial Level”)(0)(“ value”),但它不起作用。

非常感谢您。

JSON数组转换为VBA集合-这些索引从1而不是从0开始索引

尝试一下:

jsonStr = Range("I10").Value 'your json sample
Set json = JsonConverter.ParseJson(jsonStr)(1)

Debug.Print json("Features")("Level")(1)("value") '>>228.108000000000
Debug.Print json("Features")("Level")(2)("value") '>>3143.513000000000
