You will at least need Excel on your laptop/PC. Therefore, make sure you have that program installed prior to the training. Recommended is Office 365 or 2021, but also earlier versions (after 2010) can participate. For ‘Excel for Beginners’ a Macbook is still usable. For the training ‘Excel essentials for Data’ and ‘Data Analysis with Excel’ it is important to work with a Windows laptop or PC.
