NUMBERS Document Format

NUMBERS Converter

Numbers is Apple’s spreadsheet software, and it is equivalent to programs like Microsoft Excel. It’s included as standard on Apple’s operating systems iOS, iPadOS and macOS as part of Apple’s iWork suite. This means the full Numbers app is installed automatically on iPhones, iPads and Macs. Many people with Apple devices use Numbers because they can create, view and edit spreadsheets on their Apple devices without an extra software subscription or purchase.

Numbers lets users create spreadsheets from scratch or from templates, entering data into cells. You can also use it for calculations and pivot tables, and to create charts and graphs. As it’s Apple’s format, NUMBERS files will not open directly in Microsoft Excel or other spreadsheet programs. However, you can use the Numbers program or an iCloud account to save spreadsheets into CSV, XLS or XLSX format.

XLSX Document Format

XLSX Converter

XLSX is a file type created using Microsoft Excel - part of the Microsoft Office Suite software. This file format is a zipped Open XML-based file type, meaning it compresses or reduces the file size so that it can access stored data faster and be easily shared with other programs. XLSX was developed by Microsoft as part of their Office 2007 development and is now the default file format for Excel.

XLSX files are very similar in their functionality to their predecessor, XLS; they can be used to create spreadsheets, charts and graphs, process mathematical formulae, and to share or analyse data. The main difference between XLSX and XLS is in how the data is stored. Whereas XLS files hold data in a single file, XLSX saves data in the Open XML format, with separate files zipped up together to reduce space. This also means that XLSX files can present larger data sets and have a greater range of cells. As well as with Microsoft Excel, XLSX files can be opened using various other programs, including Google Sheets, LibreOffice, and Apple Numbers.
