NZD money converter

The tool focuses on converting monetary values involving the New Zealand dollar (NZD) and other major currencies. It serves travelers, freelancers, small businesses, and finance teams that need quick, accurate currency conversions for pricing, invoicing, and budgeting.
Conceptually, a base rate is retrieved for the from_currency to to_currency pair and the input amount is multiplied by that rate to produce the converted amount. If a direct rate is unavailable, a cross-rate via an intermediary is used.
Key features include real-time rate retrieval, support for historical dates, and outputs that include both the converted value and the rate used. Optional formatting and locale considerations help ensure consistency in invoices.
The tool's unique value lies in NZD-centric workflows, fast turnaround, and the ability to export results for reporting, with robust validation for input correctness and error states in cases of data unavailability or invalid currencies.
