Open a spreadsheet in Numbers on iPhone
You can open Numbers spreadsheets saved on iPhone, in iCloud Drive, on connected servers, in other third-party storage providers and on an external storage device that’s connected to your iPhone. You can also import 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 on iPhone.
Note: When you open a spreadsheet saved in iCloud Drive, it’s automatically downloaded to your device.
