This is not true when you are writing code you haven't tried before. It's true for html, Css, devops stuff.

Or if you are trying to come up with an algorithm that is complex. Doing that in open office is impossible for me.

Unless you’re just reproducing a high fidelity mock-up from a designer, HTML/CSS work absolutely can include experimentation. And I’d argue that this is pretty important if you want web apps that are at all pleasant to use.
