"excel sheets require nowhere near the manpower required for your alternative. That factors into a cost-benefit analysis that may not favor real development."

Not to build, but to maintain and constantly clean up the errors by using the wrong tool for the job. I know form experience having wasted countless hours because my organisation insisted on using it as a tool to upload data to our database, and using it as the database before that.

The errors they invariably introduce are also very expensive. Not just fixing them, but actions on incorrect data can be very very expensive. I've seen it, and in my experience its almost universal.

I'm not saying Excel is always the wrong solution, I am saying Excel is not always the right solution but it can appear to be. That makes it very dangerous.
