LocalQL
LocalQL is a DuckDB-powered tool for querying local CSV files with SQL. Install
the localql package to use the csvql command, organize repeatable work in a
.csvql.yml project catalog, export results, and optionally work in a terminal
menu.

Install and first query
Install the core command in your selected Python environment:
python -m pip install localql
csvql --version
To try a query, create a small CSV in the directory where you are working:
python -c "from pathlib import Path; Path('orders.csv').write_text('order_id,status\nORD-1,paid\nORD-2,pending\nORD-3,paid\n', encoding='utf-8')"
csvql query orders.csv "SELECT * FROM orders LIMIT 5"
The file name becomes the SQL table name, so orders.csv is available as
orders. A successful command prints a table with the CSV rows. See
Getting started
for project catalogs, saved SQL, and exports.
Optional terminal menu
The core CLI needs only localql. Install the optional Textual-based terminal
menu when you want a source list, SQL editor, results, and history in one
terminal application:
python -m pip install "localql[tui]"
csvql menu orders.csv
All core commands remain available without the extra. See the Terminal menu guide for keys and source-management actions.
Compatibility and safety
LocalQL supports Python 3.11 through 3.14 on macOS, Linux, and Windows.
LocalQL treats user-authored SQL as trusted local DuckDB SQL. It does not sandbox DuckDB or restrict filesystem access. Run only SQL you trust.
Core workflows
| When you want to… | Start here |
|---|---|
| Query a CSV or join named tables | CLI reference |
| Reuse a project catalog and saved SQL | Project catalogs |
| Inspect, sample, or profile a source | Inspect, sample, and profile |
| Export a result or reuse it as a CSV source | Save and reuse results |
| Check configured data-quality rules | Data-quality checks |
DuckDB executes SQL; LocalQL manages local CSV table aliases, project configuration, output, and explicit exports.
