Extract text from backup and attribute files (ATB)
To convert ATB backups to another format, you need AnyTime Organizer or other Data software.
To convert other file formats to the "Backup Archive" file type, you need software like AnyTime Organizer or a similar tool.
The .ATB file extension is most commonly associated with AnyTime Organizer, a personal information management (PIM) suite by Individual Software. These files serve as backup archives, storing critical user data such as calendars, address books, to-do lists, and sticky notes. The primary constraint with .ATB files is their proprietary nature; they are often structured as Microsoft Compound documents or custom binary blobs that cannot be opened by standard text editors or modern calendar apps like Microsoft Outlook or Google Calendar directly.
Users typically encounter friction when migrating away from legacy PIM software. Without the original AnyTime Organizer installed, accessing the schedule or contact list inside an .ATB file is virtually impossible. For data recovery or migration, the best workflow is to use the original software to restore the backup and then export the data to CSV (for spreadsheets) or ICS (for calendars). If you simply have the file and no software, conversion tools can attempt to extract raw text strings, though formatting will be lost.
A secondary, distinct use case involves video games developed by companies like Bandai Namco. In this context, .ATB files function as Attribute Tables, defining stats, weapon parameters, or vehicle handling data. Modders often seek to convert these binaries into JSON or XML to edit game values. Finally, in scientific contexts, .ATB may refer to Audio Precision test data, which requires specialized engineering software to view.

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 ATB converter.
