Delete a spreadsheet
You can delete a spreadsheet from your Mac or from iCloud. Deleting a spreadsheet from iCloud removes it from all of your devices synced with iCloud and moves it to the Trash on your computer.
Delete a spreadsheet
Choose File > Open (from the File menu at the top of your computer screen).
Choose either iCloud or On My Mac.
Drag the spreadsheet to the Trash icon in your Dock.
The spreadsheet isn’t deleted from your computer until you empty your trash.
