How to import excel calender data into outlook - with a click of a button

[levrone]

Dear forum,

I need to come up with a way to import calender data from excel. My office is trying to coordinate calender data from other companies which they then can have the option to integrate into their own calenders. I have been googling around and the process seems, at first sight, to be way to laborious. Is there a way to (through initial programming or other ways) to create an excel sheet with data where a people can, with a click of a button, import the calender data in the targeted coloumn into their own outlook calender - without downloading any additional software? Non-clouding solutions are prefered.

Thank you in advance
