' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim success As Long
Dim http As New ChilkatHttp

' Get the JSON we'll be parsing..
Dim jsonStr As String
jsonStr = http.QuickGetStr("https://www.chilkatsoft.com/exampleData/qb_customer_balance_detail_report_2.json")
If (http.LastMethodSuccess <> 1) Then
    Debug.Print http.LastErrorText
    Exit Sub
End If

Dim json As New ChilkatJsonObject
success = json.Load(jsonStr)

' As an alternative to manually writing code, use this online tool to generate parsing code from sample JSON: 
' Generate Parsing Code from JSON

' Let's parse the JSON into a CSV, and then save to a CSV file.
Dim csv As New ChilkatCsv
csv.HasColumnNames = 1

' Set the column names of the CSV.
Dim numColumns As Long
numColumns = json.SizeOfArray("Columns.Column")
If (numColumns < 0) Then
    Debug.Print "Unable to get column names"
    Exit Sub
End If

Dim i As Long
i = 0
Do While i < numColumns
    json.I = i
    success = csv.SetColumnName(i,json.StringOf("Columns.Column[i].ColTitle"))
    i = i + 1
Loop

' Let's get the rows.
' We'll ignore the Header and Summary, and just get the data.
Dim row As Long
row = 0
Dim numRows As Long
numRows = json.SizeOfArray("Rows.Row[0].Rows.Row")
If (numRows < 0) Then
    Debug.Print "Unable to get data rows"
    Exit Sub
End If

Do While row < numRows
    json.I = row
    numColumns = json.SizeOfArray("Rows.Row[0].Rows.Row[i].ColData")
    Dim col As Long
    col = 0
    Do While col < numColumns
        json.J = col
        success = csv.SetCell(row,col,json.StringOf("Rows.Row[0].Rows.Row[i].ColData[j].value"))
        col = col + 1
    Loop
    row = row + 1
Loop

' Show the CSV 
Debug.Print csv.SaveToString()

' Save to a CSV file
success = csv.SaveFile("qa_output/customerDetailReport.csv")
