Jupyter AI leads the open-source options for spreadsheets & data analysis at 61/100, with 4,426 GitHub stars. 3 of the 9 tools tracked for this job publish their source, so you can read it, fork it or self-host it. The highest-scoring tool overall is ChatGPT (78), which does not qualify: The broadest feature set in one place: Deep Research, code-executing data analysis on uploaded spreadsheets, voice mode and a huge library of custom GPTs.
Same evidence score as the ranking — GitHub stars, Hacker News mentions, release activity, free access — recomputed nightly, never sold. See all 9 tools for spreadsheets & data analysis.

+ Model-agnostic and installs like any other Jupyter extension.
− You supply and pay for the model; setup is not one click.
+ Shows the generated code, so an analyst can audit the answer.
− Needs an LLM API key, and generated code can be quietly wrong.
+ Every click becomes real pandas code you can keep and rerun.
− Only useful if the work already lives in Jupyter.
