The Scenario
Month-end close is tomorrow. You're a finance manager. The expense report for the month has 500 rows — amounts in EUR, GBP, JPY, AUD, CAD, and SGD. The accounting system only accepts USD. You need a USD equivalent column before you can close the books.
Last month someone used exchange rates from the start of the month instead of the transaction dates. The variance caused a restatement.
The bad version:
- Open an exchange rate website, find each currency manually, type rates into reference cells, write VLOOKUP formulas — 6 lookups, 500 calculations, and one wrong cell that cascades.
- Copy today's rates into a rates table and VLOOKUP against it — which requires remembering to update it every close, something that has already been forgotten once.
- Use a formula that calls an exchange rate API — requires enabling an add-in, authenticating, figuring out the syntax, and handling rate limits.
The auditors want a clean, traceable expense file before noon tomorrow.
The Easy Way: One Prompt in SheetXAI
SheetXAI reads your Excel workbook and calls Interzoid's live USD exchange rate API for every distinct currency in your report.
For each row where column C holds a currency code and column D holds an amount, call Interzoid to get the live USD exchange rate and write the USD equivalent to column E.
What You Get
- Column E: USD equivalent per expense row using Interzoid's live rate at the time of the run.
- A timestamp note recording the date and time of the rate pull for audit traceability.
- Rows with unrecognized currency codes flagged in column F for manual review.
What If the Data Is Not Quite Ready
Currency codes are inconsistent — "EUR", "Euro", "€" mixed in
Before looking up exchange rates, normalize all currency values in column C to standard ISO 4217 codes and write to column D. Then call Interzoid for live USD rates using column D and write USD equivalents to column E.
You want one rate per distinct currency rather than 500 API calls
Look up the current USD exchange rate for every distinct currency code in column B using Interzoid and write the rate to column C, then calculate USD value as column D divided by the rate and put it in column E.
You need the exchange rate itself in the workbook for audit purposes
For each distinct currency code in column C, call Interzoid for the live USD rate and write the rate to column E. Calculate USD equivalent as column D times column E and write to column F.
Full month-end conversion in one shot
Normalize all currency codes in column C to ISO 4217 format and write to column D. Build a rates lookup table on a new 'Rates' worksheet. Write the exchange rate to column E and USD equivalent to column F. Add a timestamp at the top of the workbook with the date and time of the rate pull. Flag rows with unrecognized currency codes as 'UNKNOWN CURRENCY.'
The close file is ready for the auditors with a complete rate audit trail.
