Official DuckDB WASM in the Browser

Run SQL with DuckDB in your browser. Query remote Parquet, CSV or JSON files by URL, or create your own tables.

SQL

Press ⌘/Ctrl + Enter to run. All statements run; DuckDB returns one result set (normally the first query's), and up to 1,000 rows are displayed. Tables you create are kept in memory until you refresh. Extensions such as spatial load with INSTALL spatial; LOAD spatial;, and geometries display as WKT. Large integers and decimals appear as strings, timestamps in UTC, and BLOBs with \x escapes.
