Excel is exactly what people should think of when "low code" comes up. All these other tools like Retool, Accern, UIpath, Webflow etc etc are immature and haven't fully proven their use cases, so of course they're easy for an experienced developer to start criticizing. Ask those same developers if they'd want to use code for everything an experienced finance or accounting person uses Excel for. You can -- and there are cases where you should in fact be using Python or R. But generally, no. Excel is the perfect tool for its (very large) market niche, and all this current low / no code trend amounts to is people searching for more market niches.
