I have an excel file and a Smartsheet. I am unable to copy paste from the excel into the Smart Sheet. Am I missing something? Video HERE
Macquarie Bank eh? Hmmmmm. Give me a discount on Sydney Airport parking and we'll talk .
But seriously.... from what I can see, you seem to move between clicking in the Smartsheet cells to paste and clicking on them. I've found that using Crtl-C and Ctrl-V to copy and paste from external applications works best (as it eliminates browser restrictions).
In short, there should be no reason why you can't do what you were trying to do. Depending on whether or not it is feasible, have you considered importing your Excel sheet into Smartsheet?
