Pull Open Exchange Rates data into Microsoft Excel

Hand this to your AI

The finance workbook in Microsoft Excel still converts this month's invoices at a rate someone typed in last quarter.

Paste this into your AI assistant. It loads Open Exchange Rates into your data warehouse, joins the rates to orders and invoices by date and currency, and pulls that Data Mart into Microsoft Excel through the add-in.

The prompt

give me a Microsoft Excel workbook of this month's orders and invoices converted to our base currency at each day's Open Exchange Rates rate, refreshable before close

S00 · Why

Why Open Exchange Rates does not go straight to Excel

A rates feed can be pasted into Excel, but not reliably, at scale or business-ready. A typed rate goes stale, and two workbooks quietly use two different rates. The data warehouse keeps one rate table and joins it to the money first.

  • Open Exchange Rates publishes the rate, not how your numbers use it
  • The data analyst joins rates to orders and invoices by date and currency
  • Every workbook converts on the same basis

Step 1: Load Open Exchange Rates into your data warehouse first

Create a Data Mart with Open Exchange Rates as the data source and choose where the data lands. Any popular data warehouse works.

  • One endpoint, Historical exchange rates data, with four fields: date, base, currency and rate
  • Authorize with your Open Exchange Rates App ID
  • Open the Open Exchange Rates connector for your data warehouse below

Step 3: Pull Open Exchange Rates data into Excel with the add-in

In Excel, add the OWOX Data Marts add-in and sign in. Choose the published Open Exchange Rates Data Mart (Historical exchange rates data), tick the columns you want and press Create & Run.

  • Tick date, currency and rate; base comes along
  • The workbook reads your data warehouse, so the App ID stays out of the file

Step 4: Refresh the Open Exchange Rates workbook when you need it

Refresh when you close a period. The imported columns update; the converted-amount column you added keeps pointing at them.

  • A formula multiplying amount by rate survives
  • Refresh on demand, with no job to configure

Why OWOX

Why OWOX for Open Exchange Rates in Excel

A pasted rates tab keeps Excel moving. OWOX keeps one rate table that every workbook reads.

  • One rate for every report. Orders and invoices join the same table by date and currency.
  • Currency logic defined once. settled_revenue lives in the data model, not in forty workbooks.
  • Your conversions stay. Refresh rewrites the imported rate columns only.
  • Maintained for you. No feed to re-paste when a currency is added.
