Data Analysis Skill

Overview

This skill analyzes user-uploaded Excel/CSV files using DuckDB — an in-process analytical SQL engine. It supports schema inspection, SQL-based querying, statistical summaries, and result export, all through a single Python script.

Environment setup

Prepare the Python environment before running analyses. Install the required packages explicitly using the same interpreter that will run the script:

python -m pip install duckdb openpyxl

If either package is missing, the script exits with a setup instruction; it does not invoke an installer or modify the environment. DuckDB's existing spatial-extension setup for loading files is unchanged.
