Copy and paste issue

I am trying to copy 40 rows and 5 columns of numbers from Excel and paste into Smartsheet. Each cell in Excel has a single number (in general format) and when I try and past into Smartsheet, it puts the row of numbers vertically or if I hit Ctrl+V it comes up with text I copied a long time ago. I have tried copying the numbers into a clean Excel spreadsheet before pasting without formatting into Smartsheet, but I am having the same issue. I'm sure it is user error, but I don't know what I am doing wrong. Any ideas of my error would be most appreciated.
