Is my Parquet file uploaded or stored when I use this viewer?

No. The Parquet viewer runs entirely in your browser. Your Parquet file is parsed in memory and is never uploaded or stored on any server.

How can I view a Parquet file on Windows, Mac, or Linux?

Open this online Parquet viewer in a modern browser, drag and drop your .parquet file, and the tool will show the schema and preview rows without installing any desktop software.

How large can a Parquet file be?

The viewer can handle reasonably large Parquet files, but it is still limited by your browser memory and CPU. For very large datasets, split the file into smaller parts or sample a subset first.

Can I filter rows with SQL in this Parquet viewer?

Yes. Switch to the SQL tab and run queries like SELECT * FROM data WHERE column > 0 to filter rows on top of the loaded Parquet file.
