ParquetCSVParquet to CSV Converter
Somebody sent you a .parquet file and Windows has no idea what it is. There is no double-click answer, and every guide tells you to install Python. DataTray opens it, shows you the rows, and writes a CSV.

Drop in your files — CSV comes out UTF-8 with a BOM, so it opens in Excel in columns.
Why convert
Why Parquet is everywhere now
Parquet is columnar and compressed, so it is often a fraction of the size of the equivalent CSV and much faster for analytics tools to read. That makes it the default export from data warehouses and pipelines — and it means non-technical recipients get handed files their machine cannot open at all.
- Opening a file a data team sent you, without asking them to re-export it.
- Converting a directory of partitioned Parquet files into one CSV.
- Getting warehouse output into a spreadsheet for someone who does not use SQL.
- Inspecting a Parquet file's contents before you build anything on it.
How it works
Convert Parquet to CSV in a few clicks
- 1
Open the Parquet
A single file, or a whole directory of partitioned parts read as one table.
- 2
Look before you convert
The rows are shown immediately, so you can check it is the file you meant.
- 3
Write the CSV
Or an .xlsx if it is going to somebody who works in Excel.
