What is XLSX file format?
A file with an XLSX extension is a file of Microsoft Excel Open XML Format Spreadsheet. It is a ZIP archive of spreadsheet files created by Microsoft Excel 2007 and above based on XML.
The XLSX file stores the cell editing data in the worksheet, while the worksheet is stored in the spreadsheet (the file contains multiple worksheets). The cells in a spreadsheet are positioned in rows and can contain styles, formats, mathematical functions, etc.
Earlier versions of Excel spreadsheet files were saved in XLS format, and XLSM files are Excel sample files that support macro command functions.
How do I open an XLSX file?
Unless you have installed a software on your computer that can open XLSX files, you will not get any response when you click on XLSX files. Instead, you must have spreadsheet software installed on your computer in order to edit XLSX files.
Although Microsoft Excel (2007 or later) is the most common software used to open and edit XLSX files, you can also install Microsoft Office Compatibility Pack and use older versions of Excel to open, edit, and save XLSX files.
It also supports printing and copying data from XLSX files, which are features you will probably need.
If you don’t want to edit an XLSX file but just want to view its contents, you can install the free Microsoft Office Excel Viewer which also supports printing and copying data from XLSX files, which are features you should use.
Also, if you’re using a Mac operating system, Apple Numbers supports opening and editing XLSX files, but you may not be able to use all of the features.
If you don’t want to install software, Google Sheets, Microsoft Excel Online, and Zoho Docs are free online applications that can open and edit XLSX files. However, to operate these tools, you must first upload XLSX files to the website before you can view and edit them.
If you are using Chrome web browser, you can install the extension Office Editing for Docs, Sheets & Slides, which allows you to open and edit XLSX files directly in your browser, drag and drop XLSX files from your computer to Chrome, and start editing them directly.

If you have tried all the suggestions above and the file still won’t open, then the most likely reason is that you are not actually working with XLSX files. This could happen if you simply glance at the subfile name and mistake it for an Excel file.
For example, your file may actually end in .LSX, which is a Streaming Media Shortcut file and has nothing to do with Excel, and Windows Media Player can open LSX files.
Similarly, it is easy to confuse it with an SLX file, but SLX files are also not related to Excel and are used in programs like Simulink and SpectraLayers. xlr is another subfile name that can be easily confused with Excel files.
