Ever have someone send you an XLSX file and you can't open it? You know that the new format has been out for some time now, and becuase of this embarrasment factor you don't want to have that person resend it as a XLS, or it's too late in the day and you really have to get at the information.
The next step is to turn to the internet on the search term: "convert xlsx to xls" and you get all these sites that will do it for free, but you have to give them your email address, or you have to download something, or you spend all your time clicking through their heirarchy of pages and then their "free" converter does not work.
OK, the answer is simpler than you realized, and you don't have to do anything risky or buy anything. If you have a gmail email address then the solution is easy.
Just log into your gmail account and across the top of the page you'll see the navigation that shows your Google+, Search, Images, Mail, Drive, Calender, Sites, Groups, Contacts, More.
Click on Drive.
That's right! This nifty free tool will convert your file for free and it's safe. Just look for the red icon on the left that says:
Create | (upload)
Pick upload and select your xlsx file.
Once up on the Google Drive site it's ready to view.
Now that it's open, you can see it, but Even better you can do the conversion and save it to your desktop right from this window: All you have to do is select from the top Menu: "File" > then > "Download As" > and select "xls".
And then select the location on your drive you would like to save it.
Be safe out there on the internet.
