Interestingly, a few weeks ago I fed Claude a curve from a datasheet (actually a screenshot from the web) via its UI with some of its internal tools enabled, and, with minimal prompting, it turned that plot into an interactive tool that analyzed it. (Good results took four attempts, all in the same conversation. Try 1 had JS errors and did not work at all. Tries 2 and 3 had problems with the visualization. Try 4 was usable.) Oddly, Claude corrupted some of the text in the sheet.

I would not trust this for real work — a real tool like SheetScan is likely much more reliable and is unlikely to hallucinate data.
