Little program to convert (phone) contacts from iPhone to Samsung Galaxy (Android), from SQLite to VCard. Simple PowerShell script. Created in my free time for a colleague, who moved from his old iPhone 6s to a new Samsung Galaxy S9+. Successfully converted 1008 contacts from SQLite to VCards.

Feel free to use - see MIT licence. Feel free to create an issue if assistance/guidance is needed.

Extracted database-file from an (unencrypted) itunes-backup. Path: /Home/Library/AddressBook/AddressBook.sqlitedb Structure is explained in the script. Basically, it's 2 tables, one containing the Persons and the other containing every related Person's ContactInformation (web, mail, phone, etc.).

• connect your iPhone to the PC (USB)
• use Windows iTunes (Windows Store) to create a local (unencrypted!) backup
• backup will be saved at "%USERPROFILE%/Apple Computer/MobileSync/Backup" (other paths are known, look it up)
• download: https://www.giga.de/downloads/iphone-backup-extractor/ (free version sufficient, 4 "objects" is enough)
• open created backup with the extractor tool
• use "Expert-Mode" to see all files/folders directly
• see also: https://support.apple.com/de-de/HT204215
• search for "Home/Library/AddressBook/AddressBook.sqlitedb".
• extract and save on PC (contains all the contact information as SQLite)
