What is an Excel file?

An Excel file is a spreadsheet document created in Microsoft Excel and saved in .xls or .xlsx format. It organizes data in a grid of rows and columns, supporting text, numbers, images, formulas, and charts. Excel files are widely used in business for data analysis, financial tracking, and reporting.

File management is the practice of storing, organizing, locating, and distributing digital files.

How to open an XLS document file

The standard option to open an XLS document file is the Microsoft Excel program from Microsoft’s Office suite. This includes all the previous versions of the Excel program including the most recent.

For users without Microsoft products, there are alternatives to open the XLS extension. The most popular choice is Microsoft’s own alternative, ‘Microsoft Excel Viewer’. There’s also third party software available that opens the XLS, as well as built-in browser extensions that allow users to access and edit XLS files.

Benefits of using an XLS

XLS files are optimal for storing information that necessitates sorting in the form of rows or columns. They are capable of handling data, such as text and images. XLS files are most commonly used in a business setting. They’re capable of organizing different user inputs in ways favorable to visualizing and planning future tasks. For example, a user might input data concerning money they make from different jobs they do. They could arrange it in ways that help them prioritize their work.

A powerful way to use XLS files are to assist in analysis of important data. Another way it helps businesses is by providing valuable visuals of a large quantity of data to organize it for future use. Sometimes data is best understood when it’s sorted in a way that allows users to visually separate different pieces of it. XLS provides that opportunity better than other programs.
