If, as I suspect, you've simply got an incorrect 'View' setting applied in Excel on your laptop, the spreadsheet should open normally anyway when you open it in Excel (with a 'Normal' setting) on your desktop. i.e. there's probably nothing at all wrong with the spreadsheet file itself; it's only the way that you've told Excel to display it that's causing the problem.
However you can copy the spreadsheet file across to your desktop via a flash drive, and then open it, just as you would with any other file. i.e. open two windows side-by-side on your laptop, with one displaying the contents of the folder where the spreadsheet resides and the other showing the contents of the flash drive. Drag-&-drop the file from the former to the latter. Transfer the flash drive to your desktop, navigate to its contensts and double-click on the file.
