How to open an Excel Document in VB.NET

Hello clever people,

Completely new to VB.NET (only installed Visual Studio 2019 in the past couple of days).

To start all I want to do is open Excel (office 365) from a button on a userform. The location of the file is on a network, lets say: -

\file-svr01\Rozel\Design\Parts\PNG.xlsx
OR
R:\Design\Parts\PNG.xlsx

I don't need to read in any information from the spread sheet, just open it so thgat i can edit it.

Please bear in mind I am completely new to VB.NET, so if I have to initialise anything in the code before trying to open excel, it would be good if you can put this in any possible solutions.

I have tried using google, I've gone through lots of different web sites and tried lots of things and nothing works, but mainly because I don't really understand the syntax

Can anyone help?

Thanks.
