Carregue arquivos CSV, JSON, NDJSON ou Parquet em um espaço SQL local do navegador. Consulte colunas com DuckDB-Wasm e exporte as linhas visíveis sem enviar o arquivo.
The loaded file is exposed as data. To keep the workspace non-destructive, this tool accepts SELECT and WITH queries only and displays at most 200 rows.
