dq — Query Any Data File with SQL
A command-line tool that lets you run SQL queries against CSV, JSON, and TSV files directly from your terminal.
Quick Start
# Query a CSV file
dq "SELECT * FROM data.csv WHERE amount > 100"
# Aggregate data
dq "SELECT category, SUM(amount) as total FROM sales.csv GROUP BY category"
# Join across files (CSV + JSON)
dq "SELECT c.name, o.total FROM customers.csv c JOIN orders.json o ON c.id = o.customer_id"
# Describe a file's schema
dq describe data.csv
# Output as CSV or JSON
dq --format csv "SELECT * FROM data.csv"
dq --format json "SELECT * FROM data.csv"
# Interactive REPL
