How to Convert an XLSX Excel File to an XLSby James Highland
The XLSX file format was introduced in version 2007 of Microsoft Excel. It is a new file structure for Excel data and accommodates new features in the program. Unfortunately, while Excel 2007 automatically saves files in the XLSX format, prior versions of Excel cannot open them. It is possible to save a file from Excel 2007 in the XLS format to support earlier versions, but this must be done prior to the creation of any XLSX file. If you receive an XLSX file and are unable to open it in your version of Excel, convert the file to XLS. This common task is accomplished easily.
Visit the free online file conversion service Zamzar at www.zamzar.com. This simple website offers conversion programs for a wide variety of common software file types.
Click the Browse button in the Step 1 section of the Zamzar website. A pop-up window will appear. Find the XLSX file on your computer through this window. Click on the file and press "Open."
