What is a Parquet file?
Apache Parquet is a binary, column-oriented file format used in analytics and data processing workflows. It stores typed columns efficiently, but that means a text editor or ordinary spreadsheet cannot show it directly.
This online Parquet reader decodes the file locally and gives you a practical table plus schema details. If you need a portable text copy, use the dedicated Parquet to CSV converter. If you need a file to test with, open or download the sample Parquet file.
Plain answers
Parquet viewer questions
How do I open a Parquet file?+
Choose or drop a .parquet file up to 100 MB. The editor decodes it locally, shows every column and pages through the rows. No installation or account is needed.
Is this Parquet reader private?+
Local viewing and conversion do not upload your selected file. The separate Analyze with SQL workflow uploads it directly to private server storage; filenames, SQL, columns, and cell values are not recorded in operational telemetry.
What is the file-size limit?+
Local editing accepts files up to 100 MB and reads the complete file into browser memory. For larger files, upload up to 5 GiB in the separate Analyze with SQL section. Use the dedicated large-file viewer for local streaming previews up to 5 GiB, or the CSV converter for streaming conversion.
Can I filter and sort Parquet rows?+
Search, column filters and sorting apply to the complete decoded table. Save Parquet retains all rows in their document order. Export view downloads the filtered and sorted rows as CSV or JSON.
Can I convert Parquet to CSV?+
Yes. Open the file, optionally filter or sort it, then choose CSV under Export view. For larger files, use the dedicated Parquet to CSV converter.
Which compression formats can the viewer read?+
The browser parser includes uncompressed, Snappy, Gzip, Brotli, LZ4, LZ4 Raw, and Zstandard decompression support. Some unusual nested schemas may still display differently from flat tabular files.
