My file associations properly show LibreOffice as the app to open an XLS file.
But when I try to open an XLS file, LibreOffice Calc appears but instead of opening the worksheet, it displays a “Text Import” window, wanting me to specify how the text needs to be manipulated to create a CSV file. I just want to open the XLS file, not create a CSV.
LibreOffice it’s asking the parameters, because even the file has xls extension, it seems a csv file, once opened you can save with format you like.
