Tatsächliche Eingabe
- Duplicate definition
- For a contact export, normalized email is the business key. Two rows with the same email are possible duplicates even if name capitalization differs. Rows with blank email are never auto-matched by name alone.
- Columns and sample duplicates
- A RowID; B FullName; C Email; D UpdatedAt; E Source; F Phone. Examples: R10/Ana/ANA@example.com/1 Jun/Web/123; R14/Ana Pérez/ana@example.com/4 Jun/CRM/blank; R20/Ana Perez/blank/5 Jun/Event/123.
- Resolution policy
- Exact identical rows may be marked redundant. For the same normalized email, retain the latest nonblank values only after conflicts are shown. Blank-email near matches require human review. Never delete the raw sheet.
