What is a .XLSX file?

XLSX files are typically created by Microsoft Excel, but they may be exported by other applications, such as OpenOffice Calc, LibreOffice Calc, and Apple Numbers. XLSX files may be used to store all sorts of data in spreadsheets, including quarterly financial reports, family budgets, or personal addresses.

Since the release of Microsoft Excel 2007, XLSX files have become one of the most common file types for storing spreadsheets. The files are often sent via email between co-workers, family members, and friends looking to share data in spreadsheets that need to be viewed or modified. You can open, edit, and save those XLSX files using File Viewer Plus.
