Frequently Asked Questions

Is it safe to process sensitive PARQUET files online?

Yes. Your PARQUET data is processed entirely within your browser. No data is ever sent to a cloud server, making it impossible for your information to be stored, sold, or leaked. It's as secure as opening a file in a local desktop application.

Do I need to install software to view PARQUET files?

No. This is a zero-install, browser-based utility. You can open, filter, and query PARQUET files immediately without installing Python, R, or other data tools. This is ideal for people on restricted work computers who can't install software without IT approval.

Why is this PARQUET tool faster than other online converters?

Traditional tools require you to upload your PARQUET file to a remote server, wait for processing, and then download the result. Tabularly uses DuckDB-Wasm to process data locally in your browser. This eliminates network latency and server wait times, resulting in instant processing for even large datasets.

How does this compare to Excel for large PARQUET files?

Standard spreadsheet software often freezes or hits row limits when opening large PARQUET files. This tool handles millions of rows without slowing down, providing deeper statistical insights and faster filtering than traditional spreadsheet applications.

Can I save my filtered results back to my device?

Yes. Once you have filtered, queried, or converted your data, you can export the results as a clean file at no cost. This is an efficient way to prune massive datasets into manageable local files.

Do I need to sign up to use the PARQUET tool?

No. You can access all browser-based features immediately without creating an account or providing an email address. Our goal is to make high-quality, private data tools accessible to everyone.
