No file handy?
Drop your file here or click to upload
Parquet up to 500 MB; CSV and JSON up to 2048 MB (compressed on disk). Browser memory use depends on content.
Once you open a file, it will be saved here for quick access.
How to convert Parquet to CSV
Open a .parquet file, optionally run SQL, then export CSV.
Open your file
Drop a .parquet file, open a saved copy, or use Open from URL for a public or presigned HTTPS link. Everything stays local.
Query and explore
Optionally run SQL to inspect, filter, or transform before you convert.
Export results
Use Export → CSV (.csv). Download starts from that menu, not on drop.
Why convert here
Open a local .parquet file, filter with SQL if you need to, then export CSV.
Run SQL on the .parquet in the tab, then export only the rows and columns you need.
Conversion starts from Export → CSV (.csv). Dropping a file does not auto-download.
Same local file, different export. Use Convert Parquet to JSON when the next tool wants objects, not a sheet.
The .parquet is not uploaded to a Parquet Fox server. Use a warehouse when the file will not fit in the tab.
Need JSON instead?
Open the file, then use Export and JSON. Same workspace. Or open Convert Parquet to JSON.
