محوّل CSV إلى JSON

// Simple CSV string → JSON array
const csv = `name,age,city
Alice,30,Berlin
Bob,25,Tokyo`

const [headerLine, ...rows] = csv.trim().split('\n')
const headers = headerLine.split(',')
const json = rows.map(row => {
  const values = row.split(',')
  return Object.fromEntries(headers.map((h, i) => [h, values[i]]))
})
// → [{ name: "Alice", age: "30", city: "Berlin" }, ...]

// With the built-in fetch + a library (Papa Parse)
import Papa from 'papaparse'
const result = Papa.parse(csvString, { header: true, dynamicTyping: true })
console.log(result.data) // typed numbers and booleans

data = [row for row in reader]
print(json.dumps(data, indent=2))
# → [{"name": "Alice", "age": "30", "city": "Berlin"}, ...]
