Fair point, and I've certainly been on both sides of this equation! The Excel approach is absolutely more efficient for one-off tasks or where the goal is simply "get numbers, make decision, move on." No argument there. Where the programmatic approach shines is when: 1. The same task repeats annually/monthly (like the author's accounting example) 2. The rules or categorizations evolve over time 3. You need an audit trail of how you arrived at conclusions 4. The analysis grows more complex over time I've seen plenty of Excel wizards whose spreadsheets eventually become their own form of programming - complete with complex macros, VBA, and data models that only they understand. At that point, they've just created an ad-hoc program with a different syntax. There's a sweet spot for each approach. Sometimes the 5-minute Excel solution is exactly right. Other times, spending an hour on a reusable script saves you 10 hours next year. The real 10x move is knowing which tool fits which situation. And yes, sometimes we programmers do overthink simple problems because playing with new approaches is fun. I'll cop to that!
