In-Browser Columnar Storage Analytics & Parquet Inspection
Apache Parquet has become the de-facto storage format for modern data lakes (Databricks, Snowflake, BigQuery, AWS Athena). Inspecting Parquet files locally traditionally required heavy Python environments with PyArrow or Pandas. This tool parses binary Parquet metadata and dictionary encodings right in browser memory.
Zero-Egress Security for Sensitive Datasets
Big data files often contain confidential business transactions, customer PII, or internal telemetry. Because processing runs entirely client-side, zero rows or columns are ever transmitted over the network.

What Parquet compression types are supported?
Standard uncompressed and dictionary-encoded binary Parquet archives are parsed directly via ArrayBuffer DataView.
