This add-on will allow you to get currency exchange rates right from within your Google Sheets™. It extends Google Sheets™ with custom formulas that fetch information from "Narodowy Bank Polski". Following features are available: ➤ Get latest currency exchange rate available ➤ Get currency exchange rate for given date ➤ Get latest available exchange rate before specific date Additionally, formulas try to return useful error messages in error scenarios (like getting currency exchange rate for the date in future). I hope you will find this extension useful. In case of any questions please contact me through email. Have a great day!
