Bill of Materials (BOM) list of all the components needed can be exported from KiCad 5. With just the click of the Edit symbol fields icon Edit symbol fields icon inside Eeschema the entire BOM list will be shown. You can now press Ctrl + A or (Cmd + A on a Mac) and copy the whole table into a spreadsheet. I have tested it with Google spreadsheets and Excel and they both work. You can also use BOM plugins inside KiCad, but this involves more effort to setup. This is the complete BOM for this Atari 800XL project in CSV format as exported from KiCad. (...)
