What is a NUMBERS file?
A NUMBERS file is a spreadsheet created by Apple Numbers, a spreadsheet program bundled with macOS. It contains one or more sheets with data organized into rows and columns, and may also include tables, graphs, images, formulas, and other types of data. NUMBERS files can be created from scratch or from a template provided with the application.
Apple Numbers is part of Apple's iWork suite, which also includes Keynote (for presentations) and Pages (for documents). The application was introduced solely for Macs with Apple's iWork '08 productivity suite, but Apple later released an iOS and iCloud web version.
Numbers is commonly used to organize numeric data such as business income and expenses, monthly active users for an app or website, or church attendance. You can choose to sort and view data in a variety of ways, such as in a formatted table or chart. You can also add text, shapes, and media (photos, music, and videos) to your NUMBERS file to enhance the presentation of the data.
The NUMBERS file is the main file type associated with the Numbers program. When you save your spreadsheet in Numbers, the program creates a NUMBERS file to store the spreadsheet information. The file is similar to the .XLSX file, which is used by Microsoft Excel to store spreadsheets.
How to open a NUMBERS file
You can only open NUMBERS files with Apple Numbers in macOS and iOS. To open a NUMBERS file on a Mac, select File → Open... in Numbers.
You can also upload NUMBERS files to the iCloud version of Numbers in your web browser (requires an Apple ID). This is helpful for Windows users who don't have access to the Mac or iOS versions of Numbers. In the iCloud application you can view, edit, save, and download NUMBERS files.
