I'd like to copy multiple sheets to another spreadsheet, it doesn't seem selecting multiple sheets simultaneously is a feature. Is there a workaround, add on, perhaps an available script?
How about this? You make a copy of the original file. Then rename the new copy of the file to FILE#2. FILE#1 remains the same. FILE#2 has a copy of all the sheets/tabs as FILE#1. You then open FILE#2 and delete the sheets/tabs that you don't want. Save FILE#2. FILE#2 now has copies of the sheets/tabs from FILE#1. :)
