It is the Excel experts that have outgrown the macros and VBA capabilities, and get IT to install Visual Studio with VB.NET on their computers.
They then double down on their VBA skills and somehow get to produce something in Windows Forms, or an Excel AddIn for the task at hand and then get going with the actual work.
Then one lands on the lab and it is full of such small utilities.
In the Microsoft space, historically the true "no-code" solutions were Access Web Databases (no VBA allowed - of course they axed that whole service in 365, as they could not monetize it as well as SQL Azure), or web-capable Excel workbooks that rely exclusively on PowerPivot/functions (no VBA allowed), or web-enabled InfoPath Forms (also... no VBA allowed).
In their modern universe their equivalents are; PowerApps, PowerAutomate/Flow, LogicApps and PowerBI - just as the article states.
