Swiss IBAN Validator lets you validate Swiss and Liechtenstein IBAN numbers directly in Google Sheets™. Use =IBAN_VALID("CH...") to check validity, =IBAN_FORMAT() to add spaces, and =IBAN_BANK() to identify the bank (UBS, Raiffeisen, PostFinance, etc.). Select cells and validate in bulk with color-coded results. Free, no ads, by ERPLight - Swiss invoicing software.
