MarkoH01: Hmmm...I tried to import the file into my OWN spreadsheet so maybe that is the problem. But copy/paste would be fine as well. I would import in my own spreadsheet and then copy/paste it into the original one.
LOL, well i think there's a misunderstanding : by save : it's saved localy to one of format you choose, i should have choosen the word "exported" . However i can't import the file i saved (see my post above) , only option is to copy/paste all the content from my local file.
You could also copy/paste the content from the online spreadsheet into a blank spreadsheet file. If i understood properly what you meant to say.
i'm not sure, but the import function isn't avaible if you are connected as anonymous > that's my thinking.
in english should be in the menu "file" then "download" (don't ask me in german)
