Is this Parquet viewer private?
Absolutely. The viewer runs entirely in your browser with WebAssembly, so your Parquet files never leave your machine.
What is the maximum Parquet file size?
You can open files up to roughly 500 MB comfortably in most modern browsers. Larger datasets may load more slowly depending on available memory.
Can I use the viewer offline?
Yes. Once the page finishes loading, you can disconnect from the internet and continue exploring Parquet files offline.
How do I inspect my Parquet file?
Drop a file into the viewer, browse the schema and row groups, and drill into any column statistics — all without a server.
Should I use the Parquet viewer, schema reader, or metadata reader?
Use the viewer when you want rows plus file structure, the schema reader when you only need field names and types, and the metadata reader when you need row group statistics, encodings, compression, and column chunk sizes.
Can I convert the Parquet file to CSV after inspecting it?
Yes. If the file looks right, open the Parquet to CSV converter to export rows into a spreadsheet-friendly CSV file locally.
Open, inspect, then choose the right Parquet workflow
Start here when you need a complete Parquet reader with row preview, schema, and metadata in one place. If you only need structural details, use the Parquet Schema Reader. For row group sizes, encodings, min/max statistics, and compression details, open the Parquet Metadata Reader. When your next step is sharing data in a spreadsheet, use the Parquet to CSV Converter.
