DIRECT ANSWER
What you should know
Every vCard block needs a BEGIN:VCARD and END:VCARD boundary. A missing boundary can make the rest of a file appear to be one malformed contact.
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.
Identify the broken boundary
Open the raw or validation view and locate the first block that lacks a start or end marker. Do not insert lines based only on line count; use nearby VERSION and FN properties as evidence.
Repair and compare counts
A safe repair creates a new file and reports the number of complete cards. Compare it with the number of recognizable contact blocks in the source.
- Validate the copied file.
- Inspect the reported incomplete block.
- Apply the boundary repair.
- Validate the output and open it in the viewer.
Do not hide truncation
If the final card is cut off mid-value, adding END:VCARD may produce a syntactically complete but incomplete contact. Treat truncation as a data-recovery problem, not a cosmetic fix.
