This is incredible. I uploaded a CSV with ~6000 rows containing campaign finance data for a particularly corrupt local politician and asked "what was the total contributed amount in [year]". Not only did it produce the correct answer (in around the same amount of time it took me to calculate it on my end) but it also seemed to understand that the spreadsheet was related to campaign finance in the "summary" portion of the response.

The most useful aspect was that I could ask "what was the total contributed amount between January and June of 2020" and get an accurate answer for that as well. Since the date column is provided as an "MM/DD/YYYY" string, I would normally have to do some boilerplate work to sanitize this.

For my particular use case, the charting aspect left a few things to be desired - once I grouped campaign donations by contributor, I could only see the first 10 rows in the AI response, with no option to expand the output. But overall I was truly blown away that something like this is even possible for a small team to build.
