HOW TO USE THIS TOOL
vCard Line Unfolder, without uploading contact data
Expand folded vCard lines for inspection. The processor runs in this browser, keeps the original source unchanged, and asks you to review the result before any download.
Review the local result
Check names, phone numbers, email addresses, warnings, and field mappings. Keep the original backup until the destination accepts the new file.
Download deliberately
The expected result is .txt. Browser and destination-app support can vary, so test a small copy before a full migration.
Privacy and limitations
No contact value or filename is intentionally sent to vCard Editor analytics. Very large inputs are bounded, remote photo URLs are never fetched, and compatibility guidance does not claim a destination app has been tested unless a dated record says so.
