Parquet to CSV Converter
Convert a .parquet file to CSV in your browser. Preview the data first, filter or sort it if needed, then download the active view.
A private, preview-first conversion
Parquet is compact and typed; CSV is plain text and widely supported by spreadsheets and import tools. This converter lets you inspect the actual rows before downloading them rather than converting blindly.
The 50 MB limit applies to the compressed input file. Larger decoded tables can still be constrained by browser memory. To inspect without conversion, return to the online Parquet viewer.
Plain answers
Parquet viewer questions
How does the Parquet to CSV converter work?+
The page reads your Parquet file locally, displays its rows, and creates the CSV in this browser tab. Select Download CSV when the preview is ready.
Is the Parquet file uploaded?+
No. This converter parses the selected file locally and does not upload its contents to the site.
Does the CSV include my filters and sorting?+
Yes. The downloaded CSV contains the active filtered rows in the order currently displayed.
Why are formula-like values prefixed with an apostrophe?+
CSV cells beginning with =, +, - or @ are prefixed when exported so spreadsheet apps treat them as text instead of executing them as formulas.
