Usage Examples

JavaScript - Format Currency

const response = await fetch('https://jsonlint.com/datasets/currencies.json');
const { currencies } = await response.json();

function formatCurrency(amount, currencyCode) {
  const currency = currencies.find(c => c.code === currencyCode);
  if (!currency) return amount.toString();
  
  const formatted = amount.toFixed(currency.decimal_digits);
  return `${currency.symbol}${formatted}`;
}

console.log(formatCurrency(1234.5, 'USD'));  // "$1234.50"
console.log(formatCurrency(1234.5, 'JPY'));  // "¥1235" (0 decimals)

Python

import requests

data = requests.get('https://jsonlint.com/datasets/currencies.json').json()

# Build currency lookup
currencies = {c['code']: c for c in data['currencies']}

# Get symbol for a currency
print(currencies['GBP']['symbol'])  # "£"

# Find all currencies with 0 decimal places
no_decimals = [c for c in data['currencies'] if c['decimal_digits'] == 0]

Use Cases

• E-commerce - Display prices with correct symbols and formatting
• Currency converters - Build conversion tools with proper formatting

Data Notes

• decimal_digits indicates standard decimal places (JPY, KRW = 0)
