Help copying data from an excel sheet to another program

Hey guys!

I need to transfer the data from the excel sheet to that software. Btw if it helps the data on the excel sheet is in the same order as the software. Eg. you can just press tab and enter the next value on the software.

Thanks a lot, guys hope I can learn from yall too!
