Online Parquet Viewer
You have a .parquet file. Excel will not open it. You do not want to send the file to a viewer you do not control.
View in the tab, not on a server
Parquet Fox opens the file locally. The query engine is DuckDB compiled to WebAssembly, running in this browser. The file is not uploaded to a Parquet Fox server for open, query, or export.
Caps we actually enforce: Parquet files up to 500 MB; CSV and JSON up to 2048 MB compressed on disk. Memory use still depends on the content, not only the compressed size.
Schema, SQL, then export
The grid shows columns, types, and rows. Run SQL in the tab before you export if you only need a slice. Export formats that exist: Parquet, CSV, and JSON.
- Open a file on the homepage and drop the
.parquet. - Inspect the schema and preview rows.
- Optionally run SQL, then export Parquet, CSV, or JSON.
When this is the wrong viewer
Use pandas, the DuckDB CLI, or a warehouse when you need a scheduled pipeline, many remote tables, or a file larger than the tab can hold. The methods table is inHow to Read a Parquet File. Need a spreadsheet instead? UseConvert Parquet to CSV.
