WASM Parquet Loader

A high-performance web application that loads and reads .parquet files directly in the browser using WebAssembly and Rust.

Features

• Client-Side Parsing: Reads Parquet files entirely in the browser. No data is sent to a server.
• WebAssembly Power: Uses parquet-wasm (Rust) for efficient parsing.
• Apache Arrow Support: Converts data to Apache Arrow format for easy analysis and visualization.
• Modern UI: Built with Vite and a sleek, dark-themed interface.
