Keep data in the script (or paste sales.json). Parse and log.

Goal

Parse a kiosk JSON string and log units.

const text = '{"city":"Nairobi","units":12,"shillings":480}';
const row = JSON.parse(text);
console.log(row.city, row.units);

const text = `[\n  {"city":"Nairobi","units":12},\n  {"city":"Mombasa","units":8}\n]`;
const rows = JSON.parse(text);
console.log(rows.map((r) => r.city));

const lines = "Nairobi,12\nMombasa,8";
for (const line of lines.split("\n")) {
  const [city, units] = line.split(",");
  console.log(city, Number(units));
}

console.log("sales.json is a banner download — or paste the string as above");
