System Documentation

What problem does it solve?

This Skill enables rapid data analysis and file format conversion using the DuckDB CLI, helping you perform in-context SQL queries and transform data without leaving the command line.

Core Features & Use Cases

  • SQL analytics on CSV, Parquet and JSON: Run ad-hoc queries, transform data, and generate reports directly from CLI.
  • Data conversion & export: Convert between formats (CSV, Parquet, JSON) and produce ready-to-use outputs.
  • Reproducible workflows: Use CLI flags and dot commands to build repeatable analysis pipelines.

Quick Start

  • To run a quick query on a CSV file: duckdb -c "SELECT * FROM 'data.csv' LIMIT 10"
  • To read a Parquet file and export to CSV: duckdb -c "COPY (SELECT * FROM read_parquet('data.parquet')) TO 'out.csv' (FORMAT CSV)"
  • To inspect outputs and adjust formatting, use commands like .mode, .headers, and .separator as needed.
