DuckLocal DocsGuides and reference.

Everything about opening your data, querying it with DuckDB SQL, and building on top of it.

Open your data

Files, folders, globs, Excel workbooks, DuckDB databases and S3 — and how each becomes something to query.

Data sources

Query tabs, autocompletion, formatting, EXPLAIN, the schema sidebar and your query history.

SQL editor

The results grid, filtering, copying, export to CSV or Parquet, and the built-in charts.

Results and charts

Headless SQL with a precise JSON contract, profiling, conversion, and the official AI agent skill.

CLI and skill

Declare queries and plots in a .dash file, validate it with ducklocal check, edit it with LSP.

Dashboards (.dash)

Analysis apps — JavaScript views over the same connection, exportable as one HTML page.
