View Parquet files online
Open Apache Parquet files right in your browser: see the schema with column types, the row count, row groups and compression, preview the data in a table, and export it to CSV or JSON. Ideal for a quick look at data-lake exports, pandas / Spark output or Hugging Face datasets without starting Python.
Which compression codecs are supported?
Uncompressed and Snappy (the most common default) are supported. Files compressed with ZSTD, GZIP, Brotli or LZ4 show an error — for those, use the Query CSV with SQL tool, which reads every Parquet codec.
