What is a NUMBERS file?
A NUMBERS file is a spreadsheet document created by Apple Numbers, part of the iWork productivity suite. The format is based on a bundled package structure (a directory appearing as a file) or a single-file ZIP container (in recent versions), containing an Index.xml (or .iwa protobuf stream), metadata plist files, and embedded assets like images. It utilizes a canvas-based approach rather than a strict grid, allowing multiple isolated tables and distinct media objects on a single sheet.
How to open a NUMBERS file
This format is proprietary to the Apple ecosystem, with native support exclusively on macOS, iOS, and iPadOS via the Apple Numbers app. Windows users cannot open these files natively and must utilize iCloud.com to view or convert the file to Excel (XLSX) format. Some third-party conversion tools can extract the internal XML data, but rendering is often imperfect outside the iWork environment.
