Extract text from Apple Contacts databases (ABCDDB)
To convert ABCDDB databases to another format, you need macOS Contacts or other Database software.
To convert other file formats to the "macOS SQLite Contact Database" file type, you need software like macOS Contacts or a similar tool.
An .abcddb file is an internal database used by the macOS Contacts application to store address book entries, phone numbers, and email addresses. It functions as the local backend repository for all user contacts on an Apple computer.
This file is heavily tied to Apple Contacts and relies on the SQLite engine. Because it is built solely for application use, it comes with strict limitations. The primary disadvantage of an .abcddb file is its lack of portability. You cannot easily open this file on a Windows PC, an Android device, or a standard web browser. Furthermore, it is not a plain text file, meaning it will display as garbled characters if opened in a text editor.
Users typically need to convert this file when migrating data away from a Mac or recovering lost address book entries. The best target formats for conversion are VCF (vCard) for universal contact importing, or CSV for viewing the data as a spreadsheet. However, manual conversion from an .abcddb file may cause the loss of linked contact photos, as these are usually stored externally in a separate macOS folder.
Extracting data from an .abcddb file is difficult. It is a proprietary database schema, so standard online converters fail to process it. Usually, only the original macOS application can properly read or export the structured data. Despite this, you can use a pragmatic workaround. Just drag and drop your file onto convert.guru to identify the format, view the internal text content, and convert it when possible. If our analysis detects the underlying SQLite structure, viewing or partial conversion may still be an option.
Convert.Guru analyzes your ABCDDB file, detects the exact format, and lets you read the text inside.
Users also converted ABBU, ABCDDB-WAL, ABCDDB-SHM, ZIP, WAB, BUNDLE and BOM files.
If you want to convert ABCDDB file to DB, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB, MYD, FRM or SQL, you can use macOS Contacts or similar software from the "Contacts Database Storage" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, DB4, MDF, MDB, LDF, DB, DB3 or SQLITE files to ABCDDB, try macOS Contacts or another comparable tool in the "Contacts Database Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ABCDDB converter.
