parquet.to

View Apache Parquet files online. Inspect schemas, browse rows, and export to CSV, JSON, Excel, SQL, or XML — all locally in your browser.

View and inspect Parquet files

Drop one or more .parquet files onto the page to browse their rows in a sortable, paginated table. Click any column header to sort; use the search box or per-column filters to narrow millions of rows. Multiple files open as tabs.

Metadata, profiling, and maps

• Metadata inspector — row groups, compression codecs, encodings, and column statistics.
• Column profiler — per-column null %, distinct count, min / max / mean, top values, and histograms.
• GeoParquet map — preview point and polygon geometry on a local canvas, with no external map tiles.

Export to any format

Export the current page or all filtered rows to CSV, JSON, Excel (XLSX), SQL, XML, NDJSON, TSV, Markdown, or HTML. CSV, NDJSON, and TSV can stream directly to disk in Chromium-based browsers.

Private by design

Files are read entirely in your browser using WebAssembly. Nothing is uploaded — there is no server. You can also load a remote file by adding ?src=<url> to the page; the bytes are fetched straight from that host to your browser.
