Open a spreadsheet in Numbers on Mac
You can open spreadsheets saved on your Mac, in iCloud Drive, on connected servers and with third-party storage providers. If you can’t open a Numbers spreadsheet, make sure that you have the latest version of Numbers from the Mac App Store. If a spreadsheet is dimmed and can’t be selected, it means the spreadsheet can’t be opened by Numbers.
You can open Microsoft Excel spreadsheets (files with a .xls or .xlsx filename extension), delimited text files or fixed-width text files into Numbers and make changes to them. See Import an Excel or text file.
Some templates aren’t downloaded to your computer until you choose them or open a spreadsheet that uses one. If your connection is slow or you’re offline when this happens, images in the spreadsheet may appear at a lower resolution until you’re online again or the template finishes downloading.
