Parquet Viewer FAQ

Is my Parquet file uploaded?

No. It is read in your browser tab and never leaves your device.

Are large Parquet files OK?

Yes. Parquet is read on demand, column by column, so files bigger than your memory can often be browsed and summarised. Sorting or exporting everything needs the whole result in memory.

Which Parquet features are supported?

Snappy, Gzip, Zstd, LZ4 and Brotli compression, nested columns (lists and structs), dates, timestamps and decimals.

Can I open several Parquet files together?

Yes. Each becomes a table; combine them in SQL with UNION ALL or JOIN.
