FetchXRates - Exchange Rate API, Excel Currency Conversion

Hey Product Hunt 👋 I’m excited to launch FetchXRates today. I built it to solve a problem I kept running into: converting currencies in Excel is still harder than it should be when working with real finance files. FetchXRates offers: • Excel currency conversion with historical rates, formulas, and reference sheets • API access for latest rates, historical rates, range-based rates • 110+ currencies with historical data from 2000 onwards • A free tier to get started The Excel workflow is designed with privacy in mind: the workbook is processed in the browser, while FetchXRates provides the exchange rate data needed for conversion. Would love feedback from finance teams, accountants, developers, and anyone working with multi-currency data.
