Hello Steven,
Thanks for posting your question in the Microsoft Q&A forum.
You have a few options. Firstly, you can search for sample Excel files on the internet that align with the requirements of the tutorial. Many educational websites, forums, or data repositories offer free datasets for various purposes. Alternatively, if you can't find a suitable dataset online, you can create a sample file yourself. This allows you to tailor the data specifically to your learning needs and ensures it aligns perfectly with the tutorial's objectives. By generating your own dataset, you also gain a deeper understanding of the data creation process, which can be valuable for future projects.
