I am importing a spreadsheet of IBANs and I need a quick way to flag entries that are obviously malformed.

This feature helps you quickly flag IBAN values in an imported spreadsheet that appear obviously malformed. It reduces manual review by highlighting entries that fail basic formatting and structure checks before you proceed.

When importing a spreadsheet of IBANs, this feature scans the values and flags entries that are obviously malformed. It is designed to help you catch common issues early, such as missing characters, unexpected symbols, or incorrect overall structure. Flagged rows are surfaced during or immediately after import so you can focus review efforts where they are most needed. This speeds up validation workflows by reducing the need to manually inspect every cell. It also helps prevent downstream errors caused by clearly invalid IBAN inputs entering your system. The feature is especially useful when importing large spreadsheets from external sources where data quality varies. You can use it as a first-pass screening step before deeper validation or any operational processing. By quickly identifying likely-bad entries, you can correct typos, request fixes from the data provider, or exclude problematic rows. The result is a faster, more reliable import process with less rework later.
