Hello.

// Парсим в объект
const json = JSON.parse('{"document": {"data": {"docType": 1, "name": "С", "fiscprops": [{"caption": "З", "printable": "123456789012", "tag": 1013, "value": "123456789012"} ] }, "result": 0 }, "protocol": 1, "version": "1.0"}');

// Выводим нужное значение
console.log(json.document.data.fiscprops[0].value);
