What are XLSX files and how to open them

Are you having problems opening an XLSX file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your XLSX files.

What is an XLSX file?

An .XLSX file is a Microsoft Excel Spreadsheet file.

.xlsx (Excel Open XML Spreadsheet) is a file format used by Microsoft Excel to store and exchange spreadsheet data. It is the default file format for Excel 2007 and later versions and replaces the earlier .xls (Excel Binary File Format) as the primary format for storing Excel spreadsheets.

An .xlsx file is a ZIP archive containing a collection of XML (Extensible Markup Language) files representing the various components of an Excel spreadsheet, such as the workbook, sheets, cells, and formulas. These XML files are organized into a folder structure and compressed into a single .xlsx file using the ZIP compression algorithm.

XLSX files are commonly used to store and exchange data in a tabular format, such as financial statements, reports, and lists. They can contain various data types, including text, numbers, dates, and formulas, and can be formatted and styled using a wide range of formatting options.

How do you open an XLSX file without Excel?

There are several ways to open .xlsx files without having Microsoft Excel installed on your computer:

• Online XLSX viewers exist, but we hesitate to recommend any as it requires you to upload your XLSX file to a third-party website. Be cautious doing that, as spreadsheets often contain personal information.
• You can use a tool like Bitberry File Opener. It allows you to display and edit Excel spreadsheets without having Excel installed on your PC.
