Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final http = CkHttp();

  // Get the JSON we'll be parsing..
  final String jsonStr;
  try {
    jsonStr = http.quickGetStr('https://www.chilkatsoft.com/exampleData/qb_customer_balance_detail_report_2.json');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final json = 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.
  final csv = CkCsv();
  csv.hasColumnNames = true;

  // Set the column names of the CSV.
  var numColumns = json.sizeOfArray('Columns.Column');
  if (numColumns < 0) {
    print('Unable to get column names');
    return;
  }

  var i = 0;
  while (i < numColumns) {
    json.i = i;
    csv.setColumnName(i, json.stringOf('Columns.Column[i].ColTitle'));
    i++;
  }

  // Let's get the rows.
  // We'll ignore the Header and Summary, and just get the data.
  var row = 0;
  final numRows = json.sizeOfArray('Rows.Row[0].Rows.Row');
  if (numRows < 0) {
    print('Unable to get data rows');
    return;
  }

  while (row < numRows) {
    json.i = row;
    numColumns = json.sizeOfArray('Rows.Row[0].Rows.Row[i].ColData');
    var col = 0;
    while (col < numColumns) {
      json.j = col;
      csv.setCell(row, col, json.stringOf('Rows.Row[0].Rows.Row[i].ColData[j].value'));
      col++;
    }

    row++;
  }

  // Show the CSV 
  print(csv.saveToString());

  // Save to a CSV file
  csv.saveFile('qa_output/customerDetailReport.csv');
