💰 Automate Currency Rates Update in Invoices with Google Sheets & API

This n8n workflow automates the retrieval of live currency exchange rates using the ExchangeRate API, with USD as the base currency. It extracts essential fields like timestamp and conversion rates, then performs an upsert operation to update a primary Google Sheet tab used for invoices or financial tracking. Additionally, it appends all fetched rates to a secondary archive tab, ensuring a complete historical record for analysis and auditing.

The benefits are significant for productivity: eliminates manual API calls and spreadsheet updates, reduces errors from outdated rates, and enables scheduled runs (daily/hourly) for always-current data. It saves hours weekly for finance professionals, supports multi-currency invoicing, and integrates seamlessly without coding, leveraging n8n's no-code power.

Perfect for finance teams managing cashflows, analysts building FX dashboards, supply chain managers handling international payments, or anyone using spreadsheets for budgeting. Prerequisites include a free ExchangeRate API key and Google Sheets access; customize currencies and schedule as needed for enterprise-scale operations.
