A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I understand how disruptive this is, especially while working on your thesis.
This appears to be a limitation of Excel 2021 rather than a mouse or touchpad problem. The improved smooth-scrolling behavior allows newer Excel versions to stop partway through a large row, but it may not be included in the perpetual Excel 2021 release, so you would not see a Smooth Scroll setting. [
As a workaround, try dragging the vertical scroll bar instead of using the mouse wheel, or select the cell and read/edit its paragraph in the Formula Bar. You can enlarge the Formula Bar by dragging its lower border downward. Unfortunately, Safe Mode or changing the Windows wheel setting is unlikely to add the missing scrolling behavior.
Hope this helps. Have a nice day!
