Freezing cells in Excel can be really handy for keeping headers visible while you scroll. To freeze cells, you can use "Freeze Panes" option: Select the row below or the column to the right of the cells you want to keep visible, then click View > Freeze Panes. Is there a particular project you're working on that involves a lot of data? I'd love to hear more about it and see if there are any other tricks that might help!
