Most of the gatekeeping of what is and isn't "coding" is done by novices who don't really know what they're talking about. Beginners tend to want a hard line with "coding" on one side and "not coding" on the other, but that's not a very useful way to model interactions with computers.
It's more of a spectrum of complexity, with WhatsApp on one side and full-blown software engineering on the other. In the middle is a vast gray area, much of which could very legitimately be referred to as programming, but which equally someone might consider to be simply using an application (like Excel).
Further, what tools you use is less significant for whether something should be considered coding than is how you're using them. I'm a professional web developer, and the way that I and my colleagues use CSS is unquestionably coding. On the other hand, someone who's just styling the fonts on their squarespace page might not consider what they're doing to be coding and that's also fine.
