Convert ICS to XLSX

It should be possible to convert iCalendar data (.ics) to Microsoft Excel spreadsheet (.xls, .xlsx), but for this you will need some specialized converter, such as ICS Fle Converter. Also keep in mind that most email and personal management nowadays can import .ics files and at the same time export data in .csv format. Once you have the .csv file, you can import it to any spreadsheet editor and save in Excel format.
