I SPENT 10 HOURS VIBE-CODING A TOOL TO VISUALIZE ANY PARQUET FILE'S INTERNALS

Summary from the TLDR Data newsletter

A small browser tool parses Parquet files with Rust arrow-rs and exposes the internals that usually stay hidden: row groups, column chunks, pages, schemas, encodings, Bloom filters, sizes, and min/max statistics. It is a useful teaching and debugging aid for understanding why columnar files behave the way they do.
