以特定方式解析Excel中的JSON嵌套数组

标签: json excel vba parsing

我得到了一些帮助,但不确定是应该在原始问题中继续还是开始新的问题,因为从技术上讲这是一个新问题(我选择了新问题,但请让我知道您下次喜欢什么)

我想出了如何将标准信息集解析为不同的列。我在解析嵌套数组时遇到麻烦。到达代码的那部分时,它会给出 运行时错误5 customfields下的数组需要解析为列,但估计行数组包含需要解析为行的零件/定价信息。

这是我到目前为止编写的代码:

Sub doJSON()

    Dim JSON As Object
    ' Dim CustomFields As Dictionary
    Dim FSO As FileSystemObject
    Dim TS As TextStream
    Dim strJSON As String
    Dim ws As Worksheet
    Dim i As Long
    Dim Item As Variant

    Set FSO = New FileSystemObject
    Set TS = FSO.OpenTextFile("C:\Users\jb\VBVA Team Dropbox\Y&M \Owner Files\auto update vba macro\sb data.txt")
    strJSON = TS.ReadAll
    Set JSON = ParseJson(strJSON)
    Set ws = Worksheets("Sheet20")
    i = 3
    ws.Cells(2, 1) = "WorkOrderNumber"
    ws.Cells(2, 2) = "EstimateNumber"
    ws.Cells(2, 3) = "EstimateDate"
    ws.Cells(2, 4) = "WonOrLostDate"
    ws.Cells(2, 5) = "ScheduledTime"
    ws.Cells(2, 6) = "EstimatedDuration"
    ws.Cells(2, 7) = "Customer Name"
    ws.Cells(2, 8) = "Contact name"
    ws.Cells(2, 9) = "Location Name"
    ' ws.Cells(2, 10) = "GeoCoordinates : Latitude"
    ' ws.Cells(2, 11) = "GeoCoordinates : Longitude"
    ws.Cells(2, 12) = "MarketingCampaign"
    ws.Cells(2, 13) = "Team"
    ws.Cells(2, 14) = "WorkOrderDate"
    ws.Cells(2, 15) = "DateFinished"
    ws.Cells(2, 16) = "ScheduledTime"
    ws.Cells(2, 17) = "EstimatedDuration"
    ws.Cells(2, 18) = "Notes"
    ws.Cells(2, 19) = "PrivateNotes"
    ws.Cells(2, 20) = "SalesRepresentative"
    ws.Cells(2, 21) = "Description"
    ws.Cells(2, 22) = "Status"
    ws.Cells(2, 23) = "IsInvoiced"
    ws.Cells(2, 24) = "CreatedBy"
    ws.Cells(2, 25) = "CreatedOn"
    ws.Cells(2, 26) = "UpdatedOn"
    ws.Cells(2, 27) = "UpdatedBy"
    ws.Cells(2, 28) = "Version"
    ws.Cells(2, 29) = "CC Referred By"
    For Each Item In JSON("Data")
        ws.Cells(i, 1) = Item("WorkOrderNumber")
        ws.Cells(i, 2) = Item("EstimateNumber")
        ws.Cells(i, 3) = Item("EstimateDate")
        ws.Cells(i, 4) = Item("WonOrLostDate")
        ws.Cells(i, 5) = Item("ScheduledTime")
        ws.Cells(i, 6) = Item("EstimatedDuration")
        ws.Cells(i, 7) = Item("Customer")("Name")
        ws.Cells(i, 8) = Item("Conact")("Name")
        ws.Cells(i, 9) = Item("Location")("Name")
' THis next 2 line gives me a type mismatch error and i cant figure out why
        ' ws.Cells(i, 10) = Item("GeoCoordinates")("Latitude")
        ' ws.Cells(i, 11) = Item("GeoCoordinates")("Longitude")
        ws.Cells(i, 12) = Item("MarketingCampaign")("Name")
        ws.Cells(i, 13) = Item("Team")("name")
        ws.Cells(i, 14) = Item("WorkOrderDate")
        ws.Cells(i, 15) = Item("DateFinished")
        ws.Cells(i, 16) = Item("ScheduledTime")
        ws.Cells(i, 17) = Item("EstimatedDuration")
        ws.Cells(i, 18) = Item("Notes")
        ws.Cells(i, 19) = Item("PrivateNotes")
        ws.Cells(i, 20) = Item("SalesRepresentative")("Name")
        ws.Cells(i, 21) = Item("Description")
        ws.Cells(i, 22) = Item("Status")
        ws.Cells(i, 23) = Item("IsInvoiced")
        ws.Cells(i, 24) = Item("Metadata")("CreatedBy")
        ws.Cells(i, 25) = Item("Metadata")("CreatedOn")
        ws.Cells(i, 26) = Item("Metadata")("UpdatedOn")
        ws.Cells(i, 27) = Item("Metadata")("UpdatedBy")
        ws.Cells(i, 28) = Item("Metadata")("Version")
        i = i + 1
    Next
    For Each Item In JSON("Data")("CustomFields")
        ' this is the part of the code that gives me a runtime error 5 . i need it to pull name data from custom field
        ws.Cells(i, 29) = Item("name")(1)
        i = i + 1
    Next
    ' this next part of the code i dont even know where to start.i need to add the material and price information for each work order item and repeat all the other information like work order number for each different material/price added to the table.

End Sub

我提供了一个json文件的示例,以及一个我希望最终结果看起来像什么的示例:

The One Guard 24 mesh is fabricated from surgical stainless steel 24 mesh with .0075\" wire diameter. Self­ supporting with NO substrate, it creates an even higher flow choice. The One Guard Product helps strengthen the entire gutter system. The chassis dam of the One Gutter Guard acts as a \"culvert\" to capture the bulk of the roof water in the first zone to minimize the migration towards the front of the system. Dam also strengthens the chassis and supports the insert in snow loads or other situations. All of these features make One Gutter Guard an excellent product to keep your gutters free of any interior clog.",

    Dim head()
    head = Array("WorkOrderNumber", "EstimateNumber", "EstimateDate", "WonOrLostDate", "ScheduledTime", "EstimatedDuration", "Customer.Name", "Conact.Name", "Location.Name", "GeoCoordinates.Latitude", "GeoCoordinates.Longitude", "MarketingCampaign.Name", "Team.name", "WorkOrderDate", "DateFinished", "ScheduledTime", "EstimatedDuration", "Notes", "PrivateNotes", "SalesRepresentative.Name", "Description", "Status", "IsInvoiced", "Metadata.CreatedBy", "Metadata.CreatedOn", "Metadata.UpdatedOn", "Metadata.UpdatedBy", "Metadata.Version")
    jsonExt.pushItem head, fieldNames.keys(), , False
    ' convert json to arrays
    Dim body()
    jsonExt.toArray data, body, head, True
    ' output arrays to worksheet
    With ThisWorkbook.Sheets(1)
        .Activate
        .Cells.Delete
        With .Cells(1, 1)
            .Resize(1, UBound(head) - LBound(head) + 1).Value = head
            .Offset(1, 0).Resize( _
                    UBound(body, 1) - LBound(body, 1) + 1, _
                    UBound(body, 2) - LBound(body, 2) + 1 _
                ).Value = body
        End With
        .Columns.AutoFit
    End With
    MsgBox "Completed"

End Sub

对我来说输出如下:
