Yeah, I am an Excel guy and it can't do anything useful for me yet here- even scraping reliable data and being able to trust the results.

What some models can do well (Claude/chatgpt) not Grok, Grok seems useless at everything, is research things for you, organise the results well etc. especially if you want also to logically research ideas and premises based on first principles. It does still fail a little when researching historical documents, it's not so easy to verify the results.
