Hi everyone, engineer on ChatGPT for Excel here - we launched ChatGPT for Excel to bring the power of GPT-5.4 to Excel. Keen to hear feedback and happy to answer any questions!
I probably could find some really useful things for it to help me … but all software nowadays only works outside my earth region :(
This time even for pro.
How well does this work compared with using GPT-5.4 in Nicopreme’s Pi for Excel?
What API/approach does it use to edit sheets?
I made a CLI (+skill) so agents could edit files with verbs like `insert A1:A3 '[1,2,3]'`, but did some evals and found it underperformed Anthropic's approach (just write Python).
