Extract text from ZKTeco backups (FDT2)
To convert FDT2 backups to another format, you need ZKTeco Matrix System or other Backup software.
To convert other file formats to the "Biometric Attendance Data" file type, you need software like ZKTeco Matrix System or a similar tool.
The .FDT2 file is a proprietary backup format primarily used by the ZKTeco Matrix System. It stores biometric time and attendance records, including employee clock-in and clock-out logs, shift schedules, and hashed fingerprint or facial recognition templates. In rarer cases, .FDT2 is utilized as a financial data file for specialized accounting platforms.
These files pose a significant challenge because they are locked within a closed, proprietary ecosystem. HR professionals and payroll managers typically need to extract attendance logs for payroll processing in Microsoft Excel or dedicated HR software. However, the current format is highly restrictive. Reading the raw .FDT2 database without the original software is practically impossible. Opening it in a standard text editor reveals garbled binary data, and standard online converters fail because the internal database schema is unpublished and often encrypted.
Ideally, users need to convert .FDT2 to CSV, XLSX, or TXT to make the attendance logs readable and editable. Because this file format is difficult to open or convert externally, often only the original software can properly read or export the structured data.
Despite these limits, convert.guru offers a pragmatic workaround. Just drag and drop your file to identify the format, view its internal hexadecimal or text structure, and convert it when possible. If our analysis detects a supported underlying or embedded format - such as an unencrypted SQLite database or plain text XML structure - viewing or extracting the raw data may still be possible.
Convert.Guru analyzes your FDT2 file, detects the exact format, and lets you read the text inside.

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 FDT2 converter.
