Dear users,

As of February 18, 2025 (during the scheduled CS OTE downtime), data files on the public OTE website will be provided exclusively in the .xlsx format.

Currently, there is an active redirection from .xls files to the new .xlsx format, ensuring their availability even when using older links.
However, this redirection will be completely discontinued on the aforementioned date.

Manual data downloads will remain unaffected. Users who process data using automated tools should ensure their applications and relevant URL addresses are updated to accommodate the new file format in time.

This announcement follows the earlier notification: Change in data format from xls to xlsx on the OTE website as of December 17, 2024.

Thank you for your understanding and for making the necessary adjustments.

ICT Services Department
