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

http = chilkat.CkHttp()

# Get the JSON we'll be parsing..
jsonStr = http.quickGetStr("https://www.chilkatsoft.com/exampleData/qb_customer_balance_detail_report_2.json")
if (http.get_LastMethodSuccess() != True):
    print(http.lastErrorText())
    sys.exit()

json = chilkat.CkJsonObject()
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.
csv = chilkat.CkCsv()
csv.put_HasColumnNames(True)

# Set the column names of the CSV.

i = 0
while i < numColumns :
    json.put_I(i)
    csv.SetColumnName(i,json.stringOf("Columns.Column[i].ColTitle"))
    i = i + 1

# Let's get the rows.
# We'll ignore the Header and Summary, and just get the data.
row = 0
numRows = json.SizeOfArray("Rows.Row[0].Rows.Row")
if (numRows < 0):
    print("Unable to get data rows")

    while col < numColumns :
        json.put_J(col)

        col = col + 1

# Show the CSV

# Save to a CSV file
