Open, browse, and filter multi-gigabyte CSV and TSV files in VS Code without
breaking a sweat.
Big Data Explorer is a high-performance custom editor for Visual Studio Code
designed as a powerful alternative to Excel for massive datasets (GigaBytes and
Millions of rows) with a near-zero memory footprint.
Why Big Data Explorer?
Most CSV extensions (and even VS Code's native editor) crash or freeze when
opening files larger than 50MB. Big Data Explorer uses a Byte-Offset Paging
architecture to only read what you see.
Core Features:
🚀 Lightning Fast Indexing: Scans millions of lines in seconds using
background Worker Threads.
📉 Low Memory Footprint: Uses strictly ~12 bytes per row of RAM regardless
of file size.
🌊 Smooth Scrolling: Virtualized rendering (60 FPS) for unlimited rows.
🔍 Instant Search: Powerful filtering that scans the disk in bulk chunks
to prevent lag.
