Parquet File Viewer & Reader
Open a .parquet file to read column names and records in a table. Scroll to load more rows; file processing runs in your browser.
Quick start
- 1
Load your Parquet file
Drag-and-drop a Parquet file or click to browse. Parsing stays on your device.
- 2
Read the table preview
Review column names and sample records. The viewer shows how many rows and columns are loaded.
- 3
Load more rows
Scroll through the table to load more records. Use Close preview to choose another file.
- 4
Choose your next step
Export the loaded grid when available, or use the linked Parquet to CSV converter for conversion.
Data stays on your device
Parquet reading runs locally in your browser. This tool does not upload your file for processing.
Parquet stores data in a binary, column-oriented format, so opening it in a text editor will not show a readable table. This viewer decodes the file into columns and records you can inspect in your browser. Use the dedicated schema and metadata readers for structural details beyond the row preview.

100% Free
Our online Parquet viewer is completely free to use, with no hidden costs or subscriptions.
Privacy-Focused
Your data never leaves your device. All processing happens locally in your browser.
Fast and Efficient
The viewer loads an initial set of rows and fetches more as you scroll through the table.
No Installation Required
Use our Parquet file viewer directly in your web browser, no software installation needed.
Is this Parquet viewer private?
Absolutely. The viewer runs entirely in your browser with WebAssembly, so your Parquet files never leave your machine.
What is the maximum Parquet file size?
Files must fit the browser's available memory and the upload limit enforced by the tool. A compressed Parquet file can require substantially more memory when decoded; preview loading is not a guarantee that any file size will work.
Can I use the viewer offline?
File processing happens in your browser. The page and its WebAssembly engine must first be available; loading the page alone may not have fetched every engine resource.
How do I inspect my Parquet file?
Choose a .parquet file, inspect the column names and records, and scroll to load more rows. For field types or row-group statistics, use the separate schema and metadata readers linked below.
Should I use the Parquet viewer, schema reader, or metadata reader?
Use this viewer to read records and column names. Use the schema reader for field names and types, or the metadata reader for row-group statistics, encodings, compression, and column-chunk details.
Can I convert the Parquet file to CSV after inspecting it?
Yes. If the file looks right, open the Parquet to CSV converter to export rows into a spreadsheet-friendly CSV file locally.
How to read a Parquet file online
Choose a .parquet file to see its column names and records. For example, an orders dataset might show order_id, customer, and amount columns. Scroll to load more rows, and check the displayed row and column counts before treating a preview as the whole dataset. For field names and types, use the Parquet Schema Reader. For row group sizes, encodings, min/max statistics, and compression details, open the Parquet Metadata Reader. When your next step is sharing data in a spreadsheet, use the Parquet to CSV Converter.
Preview a file or convert it to CSV?
Use the viewer when you need to check records without first creating another file. The Export CSV button becomes available after row loading finishes and exports the grid's loaded data. Check any preview limits shown above the table. For a dedicated file conversion, use the Parquet to CSV converter linked above.
If a Parquet file cannot be opened
Confirm that the download completed and that the file is actually Parquet. Renaming a CSV or JSON file to .parquet does not convert it. If the file exceeds the browser's available memory, try a smaller export from the source application or a local data tool. Close preview lets you replace the current file without reloading the page.
