People could use R or python and do similar mistakes. I am creating a small algorithm to analyze stock prices and I am just realizing how easy is to mess up in these things. Unfortunately, these things are treated like earthquakes in some countries: it's rare, we don't care. However, bad quality of reports is not rare. But the problem is: companies do not have other ways. They are stuck with the big players (SAP, Oracle, etc.) and they can't understand why their IT stack is crap. I wish from all this Excel bashing we could have a serious talk about these tools. BEFORE writing any line of code, we must first understand deeply why professionals use Excel in this way and what we can do about it. Finally, realize that the "cloud" is not considered always "safe". People put in Excel all kind of "secret" data and they are scared of having them on a third party server. Please, consider this too when thinking about a possible solution.
