What is and How to Open a XLS File in Windows, MAC and online

What is an XLS File?

An XLS file is an Excel Spreadsheet file that is used to store and organize data. It was the default file format for Excel spreadsheets from the early days of the software until 2007, when the newer XLSX format was introduced. XLS files are based on the Binary File Format (BIFF), which is a proprietary format that is not as widely supported as the Open XML Format (OOXML) that XLSX files use.
