SKV files or semicolon-separated values which are similar to CSV files (comma-separated values), both of these files can easily be opened and viewed using a text editor.
However, when you view it using a text editor you will see the raw data instead of columned data, which you can view by opening the file in Microsoft Excel, however, if you do not have Microsoft Excel installed you can still open and view the file with a small portable software utility called ViewSKV.
Once you download the utility extract it to any folder and use it to open the SKV file, the best part about this software is that it will allow you to view the data in column format, something which you cannot do in a plain text editor.
