Free Online Parquet Viewer
Open a Parquet file and see what is actually inside it, then query it with SQL and export what you select.
What a Parquet file tells you before a row is read
Parquet keeps its schema in the file footer, so the structure is known without scanning the data: how many row groups it holds, which codec compressed it, the uncompressed size and the ratio that follows from it, the writer that produced it, and the type of every column. All of that appears as soon as you pick the file, and the rows come after.
The engine runs in your browser
DuckDB is compiled into this page, so the file is read straight from your disk and there is nothing for a server to do. Queries are read-only, which means the file you opened is the file you still have, and closing the tab leaves nothing behind.
From one file to a complete data workflow
Browse Parquet alongside CSV, JSON, databases, and S3. DBConvert Streams adds schema exploration, cross-source SQL, comparison, and repeatable conversion workflows.
