A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I tried to figure this one out too, the only way I was able to copy and paste from Excel to Gmail is going through Google Sheets. I'm starting to save all my spreadsheets on Google, although I still highly prefer Excel, and I'm able to copy the cells over to Gmail without it copying as a screenshot. Not sure if anyone already mentioned the same answer, I didn't go through the thread.
