What is FileScope?

FileScope is a free, open-source, browser-based data profiling tool for Apache Parquet files. Think of it as pandas-profiling / ydata-profiling but running entirely in your browser — no Python, no server, no uploads.

How It Works

Under the hood, FileScope uses:

• DuckDB-WASM — a full analytical SQL engine compiled to WebAssembly, capable of reading Parquet files natively
• ECharts — a powerful charting library for interactive visualizations
• Apache Arrow — for efficient in-memory columnar data handling

Features

• Drag & drop any .parquet file
• Automatic column type detection and profiling
• Distribution histograms, top values, correlation heatmaps
• Data preview with sortable columns
• Export as HTML report or CSV
• 100% client-side — your data never leaves your machine
