XLS file extension is used by Microsoft Office Excel. The MS Excel versions previous to 2007 use XLS as spreadsheet saving format. The latest versions of Excel use XLSX which is based on XML format.
The XLS file format stores the data in tabular form which is primary workspace and layout of MS Excel. This format of Excel not only allows storage of text but also allows storage of image files and graphs. This file format can be converted to XLSX file format but vice versa is not possible. All MS Office versions can open and process XLS file format.
When you install one of the applications from the list of programs that you found here, you should be able to open or edit the file with the XLS extension without any issue. However, if you still have problems with this, you may use the option of XLS file conversion to a different format.
We hope we helped you solve the problem with the XLS file.

There can be more reasons which determine that you are not able to open the XLS file (apart from the lack of the proper application installed).
First - the XLS file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the XLS file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the XLS file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the XLS file has not been completed and it cannot be opened properly).
