Excerpt

Data Analysis

Overview

Analyzes user-provided Excel (.xlsx/.xls) or CSV files using DuckDB — an in-process analytical SQL engine. Supports schema inspection, SQL querying, statistical summaries, and result export.

Poirot note: The original deer-flow skill uses a bundled scripts/analyze.py helper. Poirot doesn't bundle that script, so this version uses bash with python3 + duckdb directly. Install duckdb first: pip install duckdb.

When to Use

User uploads Excel/CSV files and wants analysis
User wants statistics, summaries, pivot tables, or SQL queries on data
User wants to filter, join, or aggregate structured data

Prerequisites

# Install duckdb if not present
pip install duckdb openpyxl

Workflow

This is the opening of the README. Read the full README on GitHub.
