I was skeptical but it is surprisingly good. Of course I double check before finalising it.
And to pre-empt the anti-AI crowd in Lemmy, I don't know what field you guys are in, but my field has plenty of data to deal with. This is talked about even before I graduated from college many years ago. "Big data" was the term iirc. In my job, there are mistakes that happen and remeasurements have to be done. The problem? I have to go through the spreadsheet cells one by one and manually change the data with the new, remeasured data. Using AI minimises this time-wasting exercise.
The current AI models are bad for more critical analysis but they are good for "secretary work".
