: With a final click, Elias converted the parsed data into a clean CSV format, perfectly structured for the payroll system.
A ZKTeco .dat file (usually named attlog.dat ) is a binary or encoded text file that contains the raw attendance logs captured by a biometric terminal. Every time an employee scans their fingerprint, face, or RFID card, a new row of data is written to this file. Inside a ZKTeco Log File
To help me tailor any automated tools or steps for you, please let me know:
: The file typically includes User IDs, timestamps (Check-in/Check-out), and verification modes (fingerprint, face, or card).
Look on the back of your ZKTeco terminal. The model (e.g., MB360, F18, K40) determines the DAT structure.
This often happens if the USB drive was removed before the data transfer was complete. Always wait for the "Success" message 1.2.1.
The method used to check in (e.g., 1 for fingerprint, 15 for face, 4 for card).
1. The File Looks Encrypted or Extracted as Garbage Characters
Is your .dat file currently showing or encrypted/corrupted symbols when you open it? Share public link
logs = read_attlog('attlog.dat') for uid, time in logs: print(f"User uid: time")
Once imported, navigate to the Reports section. The software will match the User ID from the .dat file with the employee names stored in your software database. Method 2: The Quick Way (Using Text Editors and Excel)
ZKTeco devices typically export attendance logs as a .dat file when using the USB download method. This file is not meant to be read by standard document viewers but is a designed for import into official ZKTeco management software. 🛠️ Official Software Readers
What if you don't want to install the heavy ZKTeco software? What if you are on a computer where you cannot install software, or you just need a quick CSV export?
Open-source scripts on GitHub (e.g., zkdatareader , pyzk , zkAttendanceReader ).
Method 3: The Developer Way (Using Python to Parse .DAT Files)
If you need a ready‑to‑use DAT reader script for a specific ZKTeco model or file type, please provide the device model and a sample DAT file header (hex dump of first 64 bytes).
