Automate Currency Exchange Rates Update in Google Sheets

This n8n workflow automates the retrieval and management of currency exchange rates, pulling real-time data from the ExchangeRate API based on USD as the base currency. It processes the API response to extract key fields like timestamp and conversion rates, then performs an upsert operation to update a primary Google Sheet tab with the most current rates. Additionally, it appends full rate details to a separate archive tab, ensuring a complete historical record without manual intervention.

The benefits are significant for finance and operations teams: it eliminates manual data entry, reduces errors in multi-currency invoicing or reporting, and provides always-up-to-date FX data for dashboards and models. Scheduled to run daily or hourly, it saves hours of repetitive work, enabling focus on analysis rather than data collection.

Ideal for finance teams handling international cashflows, analysts building FX-dependent models, supply chain professionals tracking costs, or anyone using spreadsheets for budgeting. Customize the sheet IDs, API key, and currencies easily—no coding required. Prerequisites include a valid ExchangeRate API key and Google Sheets access.
