What is a file conversion?

A data conversion is normally an automated process to some extent. The effect of the operation of one program is automatically the input product of another application. If that does not happen we need to help the process a little bit and convert the file on our own, e.g. XLS to XLSX. To obtain a matched structure of the data, it is necessary to use an appropriate converter.

Program for converting XLS files to XLSX files is a kind of a "binary code translator" compensating for the differences in the code or translating it in such a way so that another application could use it. For us, as users, the visible change will be only another file extension. (After converting the file, it will be the extension XLSX, while before this step we had the XLS file). For the programs, the difference is on a much higher level – either the application will be able to open a new XLSX file, or not.
