AI Transforms Excel Productivity Overnight

AI for Excel just hit a massive turning point this week—and most people don’t realize it yet.

With Copilot for Excel and Claude Sonnet 4.5, the speed difference compared to humans

is insane. I’m talking about work that used to take me three and a half days now

taking five minutes. That’s roughly a 1,000× productivity increase. Yes,

you still need to provide the data. Yes, you still need to write good prompts.

But once you do, these tools are extraordinary. Copilot shines when it comes to editing

and working directly inside existing spreadsheets. Claude is incredible at creating—from

building full analyses using Python to generating complete multi-tab Excel files from scratch.
