What you should know
FN is the human-readable formatted name used by many address books. If N exists but FN is missing, derive a display value cautiously and review it.
Before you begin
- Keep an untouched copy of the source export.
- Work on a small sample before changing a complete address book.
- Review the downloaded file before importing it elsewhere.
Why FN matters
A destination may import a card but show it as unnamed when FN is absent. N can hold family and given name components, but it does not always provide the preferred display order or style.
Derive, then review
A repair can create FN from the structured name as a fallback. Check prefixes, suffixes, mononyms, and cultures where family-name order is not represented by a simple join.
- Validate the source copy.
- Find cards with N but no FN.
- Generate a candidate display name.
- Review affected cards and export a new copy.
Keep source semantics
Do not replace N with a guessed split of FN. Preserve the structured fields and document any display-name derivation in the change notes.
