Supported Operating Systems and versions

Excel desktop

Windows OS

For the use of the Excel desktop version, Office 2016 or later is expected. If you do not dispose of a sufficiently recent version, please update or use the add-in with Excel online.


The Excel desktop version is supported on MacOS in recent versions of Excel. In older Excel versions, namely 2007 and 2010, the add-in can still be used but will perform less optimally. The timestamps sent for forecasting will be four years of. If you're using one of these older Excel versions, you can either accept this difference, update your Excel, or use the add-in with Excel online.

Excel online

The Excel online version of the add-in is supported in every browser.
