Exchange rate for an old receipt: date-based lookup and CSV evidence

Find the exchange rate for an old receipt by using the receipt date, currency pair, FXpeek source page, and optional CSV/API evidence.

简短答案

For an old receipt, use the receipt date rather than a current rate. FXpeek can provide a dated reference-rate page, CSV/API URL, and source link that you can keep beside the receipt record.

选择合适的 FXpeek 页面

If the receipt policy uses transaction dateUse the receipt date and keep the dated FXpeek page.

If reimbursement uses approval dateLook up that separate date and label it clearly.

If many receipts need matchingUse CSV/API rows and keep source URLs.

If the workflow is tax or audit regulatedDo not treat FXpeek as an authority; follow policy or advisor rules.
