How did he remove all the borders from the whole sheet? I miss that part, one video they were there and the next video the borders on the whole sheet was gone.

Hi Emmanuel, Thanks for reaching out. I believe we have shown you how to do this in the following lecture: https://learn.365datascience.com/courses/introduction-to-microsoft-excel/how-to-make-your-spreadsheets-look-professional And also here: https://learn.365datascience.com/courses/introduction-to-microsoft-excel/initial-formatting-is-key-for-creating-professional-looking-spreadsheets Please let me know if there are other things, which are not clear. Thanks! Best, Ned
