Spreadsheets have a real appeal: full control, every formula visible, nothing hidden. For people who enjoy building and maintaining one, that's a legitimate way to manage money. For most people, though, a spreadsheet becomes a second job: one more thing to update, reconcile, and eventually fall behind on.
What a budget spreadsheet is actually for
Strip away the formulas and formatting, and a budgeting spreadsheet exists to answer a small set of questions: what's coming in, what's committed already, what's left, and what's changing over time. Those are the questions that matter, the spreadsheet itself was always just one way to answer them, not the goal.
Where automation actually helps
The tedious parts of a spreadsheet: logging every transaction, converting different billing cycles to a common monthly figure, keeping a running total current, are exactly the parts that don't need a person doing them manually. When that upkeep happens automatically instead, what's left is the part that actually required a decision: is this number okay, and does anything here need attention.
The measure of a good system isn't how much control it gives you over the mechanics. It's how quickly you can get an honest answer to "where do I stand" without dreading the process of finding out.
