Let’s assume we want to create a simple spreadsheet with leisure days to list the days when we do not have to work. Afterwards this spreadsheet should then be exported into an iCalendar (*.ics)-file for importing it into Thunderbird's usual Lightning calendar add-on.
Does LibreOffice Calc provide any export possibility to convert a table into the mentioned *.ics-file without much efforts?
If not, maybe someone has a nice macro for this?
I found an old macro during my research, but maybe there is some better option available nowadays. Another more contemporary approach still seems to be under construction…
