This. I don't think those automated Excel spreadsheets are doing as great a job as people think. Every time I've been brought in to try and migrate people away from these kind of solutions, we've exposed many bugs. Some not a big deal, others costing the company real money.
In 2017 there are shockingly few cases where macro programming an Office document is an ideal solution, and it is usually a really clear sign that you're approaching the problem wrong. It was seldom a good solution even in 2010.
It's funny that in these conversations people always bring up finance. I work in finance, for a wide variety of companies making a wide variety of solutions. Excel automation is a curse. Every Excel automation is an abomination from a decade plus earlier -- islands of data, extraordinarily full of errors, security nightmares, data exposure risks, and on and on.
