Date-specific lookupJPY workflow
When the yen moves sharply: use JPY/KRW data by task
A sharp yen move changes the number used in a document, but it does not change the document date. Use the JPY/KRW observation that matches the invoice, payment, month-end, or travel-budget task, then keep the date and source URL with the record.
Month-end close or revaluation
Use the selected month-end or monthly-average JPY/KRW view and save the CSV with the close file.
Open the workflowJPY import cost or payout
Compare the dated JPY/KRW rows before and after the move, then put the source URL in the reconciliation note.
Open the workflowJapan travel budget
Convert the planned amount and compare the 30-day range shown on this page; treat it as a reference estimate, not a guaranteed quote.
Open the workflowExcel, Sheets, or dashboard tracking
Use the JPY/KRW CSV or JSON endpoint so the observation date stays attached to each row.

Use date-specific lookup or the CSV/API endpoint, then keep the date, pair, and source URL with the record.
Can I export JPY/KRW history as CSV?
