Convert Excel XLSX To XLS

excelThe XLSX format is a Microsoft Excel 2007 format that is not compatible with older versions of the said application. Luckily, there are alternatives to converting a 2007 Excel document to an older version of it. I prefer the online way but there is also a compatibility pack for MS Office that does the trick. The format is currently not supported by GMail attachment viewer or any of the online office suites like Google Docs so you have no choice but to have it converted to an old format else you will not be able to view it.

However, you can easily convert .xlsx spreadsheet to the traditional .xls format using the Microsoft Office compatibility Pack available here. This will help you open, edit, and save .xlsx files in Office 2000, Office XP, or Office 2003. More details on Office 2007 FAQ.

Alternatively, you can convert .xlsx to .xls or other text formats online using the service here. Unlike the Microsoft compatibility pack, the Zamzar .xlsx to .xls conversion services will not require a copy of Microsoft Office on your computer.

And if you have OpenOffice, Zamzar can also convert the XLSX file to OpenDocument spreadsheet format.

  1. i am having set of xlsx and pptx files, need to convert those to xls and ppt. but the command line is not doing any help.

    for the the xlsx i tried

    c:\Program Files\Microsoft Office\Office12>excelcnv -oice c:\xl.xlsx c:\xl.xls

    it gives out a xl.xls but its just the copy of my input xlsx file when i open that file in the office 2000 it gives error. i just renamed the xl.xls to, now i can see the xmls inside. so it just created the copy of my input file and renamed it to xl.xls.

    Any help on this highly appreciated.


  2. sheetconverter seems to be broken.

    Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 65 bytes) in /var/www/sheetconvert/Classes/PHPExcel/Worksheet.php on line 966

  3. Hey thanks buddy. This really helped me out a lot! I needed to send information to some co-workers but the compatibility wasn’t the same. Thanks for bridging the gap.

  4. Thanks very much for the conversion, it was a lifesaver. Makes life so much easier. It has helped many people in AZ to get their results for a big race much faster. js

  5. This post was super helpful. My past experience with Zamzar wasn’t very favorable, so I went with the MS compatibility pack. The download took seconds, and when I opened the .xlsx file it took just seconds more to convert. Usually I try to remember to save my 2007 files (at work) in compatability mode BEFORE I plan to access them from home – but this is just as quick and I dont have to worry about forgetting. Thanks!
