ChatGPT inside Excel can now audit a CFO performance workbook end to end, checking cross-tab tie-outs, flagging stale source data, and catching revenue mismatches before the file leaves the finance team.
The demo shows the tool doing four concrete things: running a QA issue log, drafting owner questions tied to specific problems, verifying model tab consistency, and delivering a binary readiness verdict on whether the workbook is fit to send.
What makes this worth watching in full is not the conclusion but the middle: seeing how ChatGPT surfaces the exact cells and tabs where data breaks down, which tells you a lot about where the integration is useful and where a human reviewer still needs to step in.
