Parquet to CSV — Export the Current Table Page Locally

What this Parquet to CSV export includes

This tool exports the current table page only. Each generated CSV contains at most 200 rows and is subject to a 50 MiB cap. Search, filter and sort the table to find the records you want, then check the displayed page before exporting. The export is a local download, not a whole-file cloud conversion service.

How to save a CSV page

Choose your local .parquet file in the Parquet viewer. Review its schema and browse the table. Use the table CSV export control to download the current page. Formula escaping is enabled by default to reduce spreadsheet formula interpretation; an explicit raw opt-out is available. Review exported values before opening them in another application.

Input limits and data fidelity

Parquet input is limited to 200 MiB. DuckDB-Wasm runs locally in your browser, and compressed data can reach memory limits sooner. Encryption and some codec variants are unsupported. CSV is a text representation of a table page, not a replacement for Parquet schema or a round-trip archive. Keep the original when types and complete data matter.

When you need every row

Use a dedicated data processing tool for whole-dataset conversion. This viewer has no SQL editor or whole-file converter. Download original preserves the selected Parquet bytes rather than generating CSV. Closing or reloading clears the session, while files you downloaded remain on your device.
