About View a Parquet File Online
Apache Parquet is the standard columnar storage format across data engineering, analytics, and machine learning pipelines — but its binary, column-oriented structure makes it completely unreadable without specialized tooling like a Python script or a full data platform, even for a quick check of what a file actually contains.
This tool reads a .parquet file directly in your browser and displays its data as a familiar table — column names as headers, rows of actual data below — along with the file's total row and column counts, without needing pandas, Spark, or any data platform installed.
For files with a large number of rows, only the first 200 are loaded and displayed, since the goal here is a quick look at a file's schema and sample data rather than a full data-processing tool — for actual data analysis at scale, a proper data engineering tool is still the right choice.
How it works
- Upload a .parquet file. Choose a Parquet file from your device.
- Review the schema and data. See column names and the first 200 rows of actual data.
- Check the total row count. The full file's row count is shown even though only a sample is displayed.
