I suppose this same type of question could apply to machine learning and other advanced analytics that could also be easily misapplied.

Do you have spreadsheets with critical errors that you're overlooking because they give you the answers you want?

Or, perhaps you have error free spreadsheets that are manually updated periodically (every day, week, month, etc.) that are an inefficient use of time?

Either way, there are both Excel-based and non-Excel based solutions to help!
