I've recently spent a lot of time testing ChatGPT, Gemini, Claude, and other AI tools with Excel, and one thing stands out: the more relevant detail you give them, the less time you spend correcting their answers.

So, to save you the bother, I've broken down the key parts of a useful Excel prompt so you can build one without starting from scratch.
