People ask me whether to use ChatGPT, Copilot or Claude and want one winner. Here is a ten-minute test you can run yourself, plus the rule that decides it: match the tool to where your data already lives.
ChatGPT cannot see your spreadsheet, which is exactly why most people get bad formulas out of it. Here are two prompts that work, with the exact wording to use and the gotchas to watch for.
Claude does not bolt onto Office, and it does not need to. Two copy-and-paste workflows that turn an Excel export and a Teams transcript into finished work.
Two practical ways project managers can use AI: turning three weeks of messy notes into a structured status report, and building a real risk register from the task list you already maintain. Exact prompts included.
Copilot in Excel can build the automation for the report you rebuild every month. Two practical tips: having Copilot write a reusable Office Script, and getting a formula column you can actually trust.
