What is a Parquet file viewer?
Apache Parquet is a columnar storage format widely used in big data ecosystems like Apache Spark, AWS Glue, and Databricks. This tool lets you open and inspect Parquet files directly in your browser — no Spark cluster, no Python environment, and no data ever leaves your machine.
Frequently Asked Questions
- What is a Parquet file?
- Apache Parquet is an open-source columnar storage format optimised for analytics workloads. It stores data column-by-column rather than row-by-row, enabling fast queries and high compression ratios — ideal for big data pipelines built on Spark, Glue, or Databricks.
- How can I open a Parquet file without Spark or Python?
- This tool reads Parquet files directly in your browser using WebAssembly. Just drag and drop your .parquet file — no Spark cluster, no Python environment, and no cloud services required.
- Is my Parquet data safe?
- Yes. Your file is processed entirely in your browser. No data is ever sent to any server. This is a fully local-first tool.
- What is the maximum file size supported?
- File size is limited by your browser's available memory. Files up to several hundred MB typically work well on modern hardware.
