A file with All the XLSX file extension is a Microsoft Excel Open XML Format Spreadsheet file. It is a ZIP-compacted, XML-established executable file created by Microsoft Excel version 2007 and later.
XLSX files arrange data in cells that are saved in worksheets, which are in turn stored in workbooks (files that contain multiple worksheets). A spreadsheet’s cells are all set columns and by rows and may comprise styles, formatting, math functions, and much more.
Spreadsheet files made in earlier versions of Excel are stored in the XLS format. Excel files that support macros are XLSM files.
How to Open an XLSX Document
Unless you’ve purposely installed a program for your computer that can open XLSX files, then double-clicking on you won’t do anything useful. Instead, you need to have.
Although Microsoft Excel (variant 2007 and newer) is the main software program used to both open XLSX files and edit XLSX files, it is possible to set up the Microsoft Office Compatibility Pack to open, edit, and then save XLSX files using an old version of Excel.
In case you have no intention to edit the XLSX file, and you just wish to see it, it is possible to install the free Microsoft Office Excel Viewer. It supports copying and printing data out of the XLSX document which could be.
You can also edit and open XLSX files without Excel, entirely free, using WPS Office Spreadsheets, OpenOffice Calc, or LibreOffice Calc. If you are on a Mac, then Apple Numbers supports XLSX documents, also (although maybe not all features will work).
Google Sheets, Microsoft Excel Online, and Zoho Docs are a couple other ways in which you can open and edit XLSX documents for free. Going this route requires you to incorporate the XLSX file before any changes can be made by you.
To edit the XLSX file in Google Sheets, you need to first upload it via Google Drive and then open which document in Google Sheets. See the picture below for help.

If you use the Chrome browser, you are able to install Office Editing for Docs, Sheets & Slides as an extension, which lets you edit and open XLSX files right in the browser, either by dragging out a regional XLSX file in to Chrome or launching one from the internet without needing to download it.
Convert XLSX File to A Different Format
If you have one of those programs we mentioned installed onto your computer, it is suggested to use the exact program to save whatever XLSX you are working with to the particular format you’re considering. This is normally done via the Document > Save as menu option.
For instance, if you’re using Excel, undergo its FILE > Save > Browse menu and choose CSV, XLS, TXT, XML, etc.. The F12 key should also function to reach the Save As window.
Just looking at the capabilities of those two services, you can convert whatever Excel document you’ve got too many different file types, such as XLSX to CSV, XML, DOC, PDF, ODS, RTF, XLS, MDB, and even picture and internet file formats like JPG, PNG, and HTML.
Can’t Open the File?
The reason why the document won’t open at this time if you have tried all the suggestions above, is that you are not addressing an XLSX file. This might happen if you have only briefly looked at the file extension and are confusing it.
As an example, maybe your document actually ends in .LSX, in which case it is a Streaming Media Shortcut document and has nothing. LSX files open.
Likewise it’d be easy to confuse an SLX file for one which gets the Excel XLSX suffix, but SLX files are also unrelated to Excel and are rather used by programs like Simulink and SpectraLayers.
Opening an XLSX file is very easy. If you have followed the steps above, then you might be able to do it now. There are also alternative tools that you can try for free. If you still need help, please let us know by dropping us a comment.
